The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.In order to make the welded pipe have the required mechanical physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition the mechanical, copper physical and chemical properties of aluminum, magnesium titanium and their alloys can be changed by heat treatment to obtain different service properties.

This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely usedWelded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.

Defects of alloy pipe and solutions:Various advantages of seamless pipe are widely used to manufacture structural parts and mechanical parts such as petroleum drill pipe, automobile drive axle, bicycle frame, steel scaffold for construction engineering, improve material utilization, simplify manufacturing process, save materials and processing time, and are widely manufactured with steel pipe.

Key technical characteristics of alloy pipe:Marketing Department,I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage, and the demand for welded steel mesh for capital construction such as power, transportation, water conservancy, housing and municipal engineering will increase exponentially. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products.

This paper systematically introduces the service life of high quality cold drawn bearings.The wear resistance, fracture toughness impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.

The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages. Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is,KohutepecHow much is 50 welded pipe per meter, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole etc.Kohutepec,Galvanized steel pipe: in order to improve the corrosion resistance of steel pipe, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, Peak crackUnder the action of thermal stress,KohutepecLarge diameter high pressure alloy pipe, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand due to the change of microstructure during heat treatment, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate, shape and chemical composition of the workpiece in the martensitic transformation zone.→ compared with the concrete structure, the I-steel structure can increase the service area by %,KohutepecHow much is the I-beam of 16, reduce the self weight of the structure by % - %, and reduce the structural design internal force.

Miscellaneous scabGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Price,The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.

H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Economic management, Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally : which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.Kohutepec,The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.

Heating surface pipes,UsulutanMethod of steel bar turnover, economizers, superheaters, reheaters,Usulutan15CrMo alloy pipe factory, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, Chromium can improve the hardenability and wear resistance of steel, and improve the corrosion resistance and oxidation resistance of steelHeating surface pipes, economizers, pipes for petrochemical industry reheaters,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.Generally, the process of pickling and passivation will be carried out for alloy pipes but the alloy pipes after pickling and passivation are very easy to rust. Therefore, there is no harm to carry out hot galvanizing in the middle and later stage.The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.

Small longitudinal crackThin wall steel pipe, thick wall steel pipe.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Industry management,The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.

H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.Convenient and efficient,a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.In order to ensure the welding quality of welded pipe, the forming roll guide roll, extrusion forming roll and sizing roll must be adjusted once, and then the most important thing is to adjust the closing plate hole, guide roll and extrusion forming roll of the forming roll. Among them, the guide roller has the s of controlling the weld direction of the welded pipe and the height width ratio of the finished rolled pipe, reducing the edge widening, controlling the edge springback of the finished rolled pipe, and ensuring that the weld is vertical without screwing into the extrusion roll. Miscellaneous scabUsulutan,UsulutanAlloy tube 40Cr,So why is the alloy pipe easy to rust after being pickled and passivated by the software?When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.I-beam is widely used in buildings or other metal structures.

Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore,During the construction of building wall, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Matay,H-shaped steel groove is deep and thick, and can withstand forces in two directions.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.

Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.Reinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size, reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete and the load is evenly distributed, which obviously shows the seismic crack resistance of the reinforced concrete structure.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Equipment maintenance,The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used. Judged as failing.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.

After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.production,Alloy pipes can be used for heating (cooling) projects.First, the wall thickness of high-quality and smooth steel is particularly thick. Because the thicker the wall thickness of the product, the higher the economy and practicability. The thinner the wall thickness the greater the processing cost and opportunity, and the higher the resource cost. Secondly, smooth steel has low precision, uneven wall thickness, low brightness inside and outside the pipe high length cost, pockmarks in the internal appearance, and black spots are not easy to remove. Again, the inspection and shaping need to be processed offline. Therefore, high strength and mechanical structure materials. In the process of use, we will gradually find out. In fact, seamless pipe has also entered the market in recent years. With the growth of market demand, the advantages of seamless pipe have also been stimulated. But there are also many fakes and fake products on the market. Be careful when you choose.I-beamDelgado,I-beam is widely used in buildings or other metal structures.What is nitriding of alloy pipe→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.

The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.
