This week (-, the market price of red copper bar rose, and the transaction was not ideal. On the bidding day of Shagang last weekend, the price was stable to support the market, and the rising of billets at the weekend drove the market up in a wave, and the price of variety wire rods also rose by yuan at the weekend. However, it was reported that the deal was very poor, which led to the price being s table for the next two days. Until Wednesday, due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving, the market lowered the price. Market price changes, Xinji rose yuan on the rd; For the future market, the off-season is coming, the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, the environmental protection inspection is becoming more and more strict, which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.Advantages and scope of application of copper tube ground heating At present, ground heating is not only a comfortable heating method, but also a symbol of modern life quality. More and more houses, public buildings, sports facilities, industrial facilities and other places begin to use ground heating radiator, which is an important part of ground heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiator in many places.MabatoUnder the action of high welding temperature, the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Bousso,antages: low production cost and high production efficiency.With the advent of heating season, the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction, steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season, and the demand for iron ore was weakened. In addition,MabatoBronze plate, the production restriction policy was issued in Tangshan today. From : on October to : on October , the production restriction measures specified in this Notice were implemented.If you want to make the copper surface become bright again, you can polish it with copper point solution. It can not only make the copper surface brighter, the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately, so that dust and dirt will not pollute the capillary gap.Regularly inspect and monitor the copper pipe to reduce the loss caused by copper pipe corrosion.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.Scheme customization,The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.Insert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux,Mabato60SI2MN alloy round steel, and the joint is assembled and can be heated.It is said that due to the optimistic future and tight resources, some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well, and the price of raw materials has risen, so the iron price has risen. The iron mills have a high enthusiasm for producing steel, so there is not much cast iron resources, and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting, the pig iron market is performing well and is expected to continue to operate strongly in the short term.

Three of the five major application fields of copper plate copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.plan,Advantages of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance and can be used in different environments for a long time.If the environment is wet, it will aggravate the corrosion of copper pipes. Oxygen in water causes corrosion.In addition, it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures, so copper pipes need to be selected for many times in other places.Mabato,I don t know how to keep the copper tube.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.In the first ten days of May, the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock, the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons, while at the end of April, the total quantity of post settlement agreements of main steel plants can exceed tons.
