Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.
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， which led to the price being stable for the next two days. Until Wednesday， 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， 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.
중성.If the copper tube is blocked during use， it is also very important to dredge it in time.
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， 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.antages: 낮은 생산 비용과 높은 생산성.

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.
