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 * * * * , * * * , 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, and the closing was flat.Advantages: good quality, fine structure, high density, 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.Vihti,The outer package can prevent surface scratches,VihtiAluminum row of cold storage, cracks and other damages.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 .

After six consecutive days of downward adjustment, there was a rebound at the bottom of the session today, but it was corrected again later, and the closing was flat.Comoros,Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Advantages: good quality, fine structure, high density, 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.Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand, the continuous decline of iron ore port inventory may end. In addition, according to the new statistics of * *, the available days of imported iron ore of steel mills are days, which is one day lower than that before the National Day, and is on the high side of history. The steel mill said that at present, the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction, the steel mill is not willing to replenish the inventory.

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, 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.Therefore, it is often used in some ah heat exchangers to Kazakhstan oxygen equipment.Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.system,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.Hygiene and health: various modifiers, additives, additives and other chemical components of plastic pipes in copper pipes.To sum up, the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment, as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year, and it is hard to improve in the short and medium term. On the whole, the market price of Shenyang copper bars may be stable tomorrow.

The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~% and the Brinell hardness (HB) is ~Test results,Disadvantages: Due to loose tissue and high pressure resistance, it is often used in some ah heat exchangers to Kazakhstan oxygen equipment.According to * * new data, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons,Vihti5083 aluminum bar, a record high; From January to September, China s iron ore import increased by % to million tons, and the annual import volume is expected to exceed billion tons. However, due to the rapid declinecline in iron ore prices, the iron ore price index once fell below $, which reduced the enthusiasm for the shipment of imported ores. In addition environmental protection inspection has become stricter, and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak,VihtiComposite copper bar, which is likely to decline further in the future.Vihti,The hard copper tube is not artificially treated after being drawn or extruded, 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.Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe, characterized by light weight, good thermal conductivity, high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes, the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
