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.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, the production restriction measures specified in this Notice were implemented.Paru ,For the production and processing of sculpted copper tubes, the sheet metal shall be first opened in the sheet metal workshop according to the dimensions shown in the drawings, which is commonly referred to as opening. Then cut the corners of these open sheets according to the height of the edge, and then use the bending machine to form the edge according to the drawing forming diagram. The shaped copper pipe shall also be installed with reinforcing ribs as required and the four corners of the shaped plate shall be welded well. The welded parts shall be sent to the grinding workshop, and the spraying surface shall be polished and the welding interface shall be polished and leveled. The polished modeling copper pipe is then sent to the spraying workshop for processing. Before spraying, the surface of the sculpted copper pipe shall be chrome treated and the process hole shall be drilled, so as to ensure that the sculpted copper pipe can be hung on the spraying line well, and the painting can be smooth without flow marks, and the color is consistent without color difference. After that, according to customer demand, the qualified products are pasted with protective film and bound with bubble film or wooden box.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.Kingstown,The price of pig iron market rose by - yuan this week, and the transaction was fair. With the increase of coke price, the cost of ductile iron in Shanxi, Henan, Liaoning, Shandong and other regions has increased. In addition, with the gradual release of downstream demand, the inventory of iron plants is not large, and iron plants have successively raised their prices. There are few iron foundries in Shandong, Jiangsu, Hebei and Shanxi and the inventory remains low. As the coke price rises and the cost increases, the price of iron foundries rises again.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.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.

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.To prevent core problems of copper tubes, the outlet tempmperature of copper tubes should be well controlled. The cooling capacity of the annealing furnace in the cooling stage should be improved by equipping a refrigeration unit for the annealing furnace, so as to ensure that the outlet temperature of copper tubes does not exceed ℃. By controlling the outlet temperature of copper tubes, the problems of the core of coil tubes and the inner wall of the purging inlet end can be solved.The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, the same below) yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan, and yuan for Taizong yuan.Discount, it shall be stacked reasonably and placed first.On the other hand,Paru 45 # round steel, 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, 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.In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However, from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun, Dada, etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.

It has excellent conductivity, thermal conductivity,The price of pig iron market rose by - yuan this week, and the transaction was fair. With the increase of coke price, the cost of ductile iron in Shanxi, Henan, Liaoning,Paru Tinned copper bar, Shandong and other regions has increased. In addition, with the gradual release of downstream demand, the inventory of iron plants is not large, and iron plants have successively raised their prices. There are few iron foundries in Shandong, Jiangsu, Hebei and Shanxi, and the inventory remains low. As the coke price rises and the cost increases, the price of iron foundries rises again.{} The excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance, which makes it a suitable choice for modern contractors to install the water pipe, heating pipe and refrigeration pipe in all residential commercial houses.In August the price of domestic medium and heavy plates fell sharply. As of August , the price center of ordinary carbon boards in leading cities had dropped to , down yuan/ton from the end of July. At the beginning of the month, affected by the macro bad news, and the recent poor performance of fundamentals, the market mentality turned to pessimism, and some traders shipped at low prices. The market inventory rose, the inventory pressure was high, the stock shortage phenomenon disappeared, and the market transaction atmosphere was cold,Paru Copper tube, the demand performance continued to decline, and the spot price fell under pressure.Paru ,Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation suitable for frequent cold and heat exchange, and large size copper tube can be produced.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.When stacking, it shall be stacked reasonably and placed first.
