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.Tangshan billets rose sharply last weekend,hail2507 stainless steel plate, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, which boosted manufacturers confidence. Today, steel prices generally rose. However, with the approaching meeting and the rainfall in the south caused by the typhoon, the construction progress of the downstream construction site is affected, which is not conducive to the continuous demand. The high spot price transaction today is weak, which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow and some businesses may reduce prices and take goods.hail,Standardize production.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.Islamabad,On October , according to the Economic and Information Commission oong Province, at the end of September , Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn. On October , the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.On October , according to the Economic and Information Commission oong Province, at the end of September , Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn. On October , the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.Disadvantages: low output, 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.

The hard copper tube is not artificially treated after being drawn or extruded,hail45 # round steel, so that it can be naturally formed. At this time, the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore, the hard copper tube is generally straight.Under 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 and also increases the sensitivity to stress corrosion.Save materials and total cost, stability and performance, and can save maintenance.plan,After : on October , continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down, and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The city s steel, coking, electric power, cement, chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October , the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan, due to the influence of industrial users & amp; quot; coal to gas& quot;, in terms of steel plant production, the support of raw materials is weak.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.Tangshan billets rose sharply last weekend, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, which boosted manufacturers confidence. Today, steel prices generally rose. However, with the approaching meeting and the rainfall in the south caused by the typhoon the construction progress of the downstream construction site is affected, which is not conducive to the continuous demand. The high spot price transaction today is weak, which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow, and some businesses may reduce prices and take goods.

The market price of Zhengzhou copper bars is basically stable, and the shipment is not good. In terms of tube blank: today, Shandong Luli tube blank slightly reduced by yuan, and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality, traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory, and there is no large replenishment plan. The demand is sluggish,hailRed copper bar, and the market price of Zhengzhou copper bar is expected to be stable and declining.Welcome calls ,Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, the dissolved oxygen and air bubbles in it will corrode it.If the corrosion on the copper surface is found to be slight, it can be erased with linen copper wire, but it is not recommended to apply oil for preservation.hail,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, and the joint is assembled and can be heated.On October , according to the Economic and Information Commission oong Province, at the end of September , Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn. On October , the elongation is ~%, and the Brinell hardness (HB) is ~
