The main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day, including * * * * , * * * , settlement price , trading volume , and position volume . The intraday tradg volume decreased by compared with the previous trading day, and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment, there was a rebound at the bottom of the session today,Zhenjiang12CR1MOV alloy plate, but it was corrected again later, and the closing was flat.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.Zhenjiang,For the deposited copper tubes, do not open the outer packaging as much as possible.For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppr plate T, red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used for various cables and wires, motors and transformers, switches and printed circuit boards; In the manufacture of machinery and transport vehicles, it is used to manufacture industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers, pumps, etc.Bhaktapur,The application of copper tube The copper tube is generally used in the heat exchange equipment, and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids, and can also be used as pressure measuring tubes in instruments; In addition, the copper pipe is relatively firm, unlike other metals, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.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.The material of the water separator is the same, the expansion coefficient is the same, and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe, the cost of the floor heating system is higher.
It is mainly used to manufacture electrical devices such as generators, buses, cables, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass, bronze and white copper. Pure copper plate is a purplish red metal commonly known as & quot; copper plate& quot;, & amp; quot; red copper plate& quot; or & quot; red copper plate& quot;.packing,ZhenjiangAluminum plate,The market price of Zhengzhou copper bars is basically stable, and the shipment is not good. In terms of tube blank: today, 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, the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season, 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, its film is damaged, resulting in erosion corrosion. The higher the water pressure, the greater the flow, and the more serious the corrosion.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.Zhenjiang,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,Zhenjiang304 stainless steel plate, 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.On October , 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.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.
