The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently, but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, it is mainly expected to make inquiries. However due to the lower price of raw materials, the price of iron mills has been lowered.The copper bar market declined steadily this week, with a decline of - yuan.

If we often use it, the problem will be smaller, but if it is placed for a long time, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Five of the five major application fields of copper plate, copper bar and copper tube: copper is used in medicine. In the s, Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s, and successfully developed the corresponding & quot; Cancer Suppressing & quot; which is successful in the near future.Among the three production methods of copper tube, the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material, the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time, but also has a mature technology, which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.

When placing they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.As the inner wall of the pipe rubs with water, its film is damaged, resulting in erosion corrosion. The higher the water pressure, and the more serious the corrosion.On the other hand, in the steel plant, the lock price of the steel plant has been falling all the time, and the order receiving is poor. The capacity utilization rate of the steel plant is low, but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising, so the market price has fallen sharply. Subsequently,La benlanta6061 aluminum bar, the futures market rebounded in a wave, and the spot price also increased with the increase. There was an instant of large volume of transactions. However, with the decline of black futures the market transaction volume shrank significantly. In addition, the inventory pressure was high, traders shipped at low prices, and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates, the drop amplitude and rate are less than those of threads.production costs,So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.Hygiene and health: various modifiers, additives, they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.Recommendation and consultation, high production cost and high price are its biggest disadvantages. Compared with other pipe fittings, the cost of copper pipe is much higher, and the connection at the copper pipe interface requires high construction technology level.How to preserve the copper tube? In order to protect the excellent performance of copper pipes from the impact of the environment, we need to do the following: First,La benlanta201 stainless steel plate, select appropriate sites and warehouses, alkali,La benlanta2205 stainless steel plate, salt, cement, etc.Advantages: good quality, fine structure, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange, large temperature difference in working environment, and large size copper tube can be produced.La benlanta,When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.antages: low production cost and high production efficiency.In consideration of the above factors, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; urban heating seasons after November by steel enterprises, the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high, and the willingness to further replenish the inventory is not strong. In terms of supply, the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection, the quantity of * * * is relatively limited. In general, the short-term iron ore market may lack upward momentum.
