According to * * new data, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons, 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, judging from the shipment of imported ores after the National Day, 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, which is likely to decline further in the future.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 policy was issued in Tangshan today. From : on October to : on October , the production restriction measures specified in this Notice were implemented.Tripoli,Standardize production.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, the demand performance continued to decline, and the spot price fell under pressure.Upper Hutt,Tangshan billets rose sharply last weekend, 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.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.In consideration of the above factors, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; urban heating seasons after November by steel enterprises, the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high and the willingness to further replenish the inventory is not strong. In terms of supply, the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection, the quantity of * * * is relatively limited. In general, the short-term iron ore market may lack upward momentum.

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.Corrosion caused by water with high chloride ion content.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.Standard requirements, and can save maintenance.The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special stability and performance, it is a copper material produced by using nanotechnology, and copper ions can be separated by conductivity, so that copper tubes can be produced with the separated copper ions. This method is very complex, requires high technology and new equipment, so only advanced foreign countries can use this production method.I don t know how to keep the copper tube.

In the middle and late ten days, although there were good news such as the rise of futures and the increase of production restriction policy in Wu an region, due to the high inventory level, traders had no desire to increase prices, most of them had shipped goods, and spot prices lacked motivation to rise. The market inventory rose significantly. At that time, and the continuous rise of inventory led to the empty market mentality.Respect for customers,Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals, has good toughness and high ductility, and has excellent anti vibration, anti impact and anti frost expansion properties.One oftion of copper tubes. The common wave shape is a single copper tube. Hyperbolic means that two different arcs overlap on the same surface, that is, starting from different circle centers, draw arcs in two radii. The red copper tube is a module made of double curves designed according to the drawings. The red copper tube is light in weight good in rigidity and high in strength. The shapes of the red copper tubes processed are different and can be processed into various geometric shapes such as arcs and spheres. It is beautiful, elegant and colorful. Let s talk about the two main methods of processing and forming the copper tube: The hot processing and forming method is to roll the copper tube to a roughly hyperbolic shape, then heat it, then place it on the mold prepared in advance, then slowly beat it with a hammer finally cut, weld, fold, polish and polish it. The whole process needs to be very careful to ensure the surface quality of the copper tube. This forming method is very suitable for parts with small model and large arc change. When the model size is relatively large and complex, it can be considered to break it into small pieces for forming, and then splice it into large pieces. For such copper pipes, the cost is high and the production period is long. Forming method of roll bending This method is to make some modifications on the roll bending machine, and change one of the shafts into a concave type and the other into a convex type. This method can form a regular copper tube like a sphere, with a small processing range, exquisite workmanship and fashionable personality of the hyperboloid copper tube, first of all, the design is very critical. Some small copper tube copanies are not mature enough in design and have not enough design experience, so they often have problems in design, Hyperbolic copper tube is very famous for preparing some details that we should pay attention to in the design. The sculpted copper tube is highly decorative, and the production and processing technology of hyperbolic shaped copper tube is relatively complex. Copper tube products with strong aesthetics. According to the design requirements, different shapes need to be molded for the sculpted copper tube, so the production process of sculpted aluminum veneer is relatively complex.Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals, has good toughness and high ductility and has excellent anti vibration, anti impact and anti frost expansion properties.Tripoli, the expansion coefficient is the same, the cost of the floor heating system is higher.Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases,Tripoli316L stainless steel coiled plate,Tripoli60SI2MN alloy round steel,Tripoli310s stainless steel plate, the quotation of iron mills continues to decline. At present, the demand and cost support are weak, and there is no positive boost. The short-term pig iron market is weak and difficult to change.It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.
