빌 레 카Some 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， Shanxi， Hebei， Henan and other regions is sluggish， and the inventory pressure of iron mills is increasing. As the price of raw materials decreases， the quotation of iron mills continues to decline. At present， and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages: 낮은 생산 비용과 높은 생산성.

Reasons for copper pipe corrosion: Air pollution.
In consideration of the above factors， more and more steel plants have stopped production since October， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition，백 림201 스테인리스 강판， the formal implementation of production limit in "+" 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.
시장.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， and the demand for iron ore was weakened. In addition， 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.

After the pipe is cleaned， the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the same below)， the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan.
견적서Red copper inventory in key areas has risen continuously， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， Jiangyin and Lecong， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market， according to the data， as of May ， the total inventory of medium and thick plates in Wuan was close to tons， increasing by tons on a weekly basis. In late April， it reached tons lower in the year， down tons from the high level after the Spring Festival， and rose for three consecutive weeks. In terms of the ovquantity， it should be said to maintain a relatively moderate level.
(Brass is a copper zinc alloy. Due to the low boiling point of zinc which is only ℃， it is very easy to evaporate during welding， which becomes a problem in brass welding.
At the opening this morning， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the current market price of * mm Linyi copper bar was yuan (ton price， the same below)， the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan.

Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper) deoxidized copper plate (TUP， TUMn) and special copper plate (arsenic copper， tellurium copper， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere， sea water， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition，백 림201 스테인리스 강판， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
