Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.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, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.Darkuleb,This phenomenon is affected by cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the plastic deformation non-uniformity and residual stress caused by thermal stress during cooling. Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, 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, etc.Jaboatao,DarkulebQuotation of No. 10 I-beam, Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe. It is to alloy the surface layer of steel so that the workpiece surface has the characteristics of some alloy steel. Aluminizing, chromizing, boronizing, siliconizing and so on are commonly used in production.Nitriding: also known as nitriding, gas nitriding is widely used in the production of alloy steel pipe.

Darkuleb40Cr large diameter alloy pipePrecautions should be kept in mind when using

X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids,DarkulebAlloy pipe quotation, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Special shaped pipe: square pipe, rectangular pipe, steel pipe for hollow rubber steel doors and windows welded by general carbon structure steel and Mn steel strip, mainly used as agricultural machinery components, steel windows and doors, etc.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.analysis,Alloy pipes can be used for heating (cooling) projects.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.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 physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system alloy steel pipe stimulates important effects.Executive standard, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Darkuleb,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance,DarkulebHow much is a steel hoop bending machine, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.
