후난 성When cutting the copper pipe of air conditioner， use tools such as clamps to fix the copper bar and then cut it， rather than fixing it by hand， to preveshaking and resulting in irregular cutting. After the cutting of the air conditioner copper pipe is completed the cut parts need to be placed in a dry place， and then processed again after cooling， otherwise oxidation will occur due to high temperature. Liu Shuchen， director of the Resource Analysis Office of the Information Center of the Ministry of Land and Resources， said that copper bar manufacturers are currently in a period of adjustment in Chinas mining industry as a whole. In the long run， the mining super cycle driven by Chinas demand has not changed， especially the growth rate of the countrys economy. After the global economy may improve in the second half of the year， the global mining industry will rise again， and the W-shaped trend will fully emerge. In the second half of the year， there were signs of stabilizing and rebounding. In terms of the macro factors affecting the bulk commodities， the factors affecting the European market of tinned copper bars have gradually weakened， and the economic conditions of China and the United States have become the key factors affecting the bulk commodities. The European economic recession is a foregone conclusion and the possibility of a crisis in the next period of time is also reduced. In recent years， the American market economy has shown the characteristics of better than expected in the first quarter and weaker than expected in the second quarter. Since January， the global price of medical copper tubes has gradually got rid of the main tone of this years shock and decline. "Air conditioning copper tubes show signs of stabilizing and rebounding. The three-month copper on the London Metal Exchange once rebounded nearly % from the years low point， and the market price has rebounded to around dollars per ton. Driven by this， products including aluminum， zinc and other products have also rebounded. Only nickel， a basic metal product， has remained weak.
On October ， according to the Economic and Information Commission oong Province， at the end of September Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel， 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.
오 크 빌The simplest way is to use copper cleaner. Brass， red copper， bronze， etc. can be used. Oil stains，후난 성구리 알루미늄 복합 배출， fingerprints， oxide layers， etc. on the surface can be cleaned with copper cleaner first.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， and the Brinell hardness (HB) is ~
The excellent performance of copper pipe The copper pipe has the characteristics of and， which makes it a suitable choice for modern contractors to install water pipes， heating and cooling pipes in all residential commercial housing.
동봉시장은 이번 주에 안정적으로 하락하여 하락폭이 ~원이다.생철 재고가 비교적 낮기 때문에， 장시의 일부 제철소는 최근 이미 구매를 재개했지만， 구매량은 크지 않다.전기 양철 구매 가격이 비교적 낮기 때문에， 구매량을 확보하기 위해 윈난 제철소의 양철 구매 가격은 약간 인상되었다.최근 강재 시장은 줄곧 흔들리고 조정 중이어서 상인들이 불안정하다.허베이， 톈진 및 기타 지역의 제철소는 이미 제강용 생철 생산을 중단했다.지금은 주로 조사가 이뤄질 것으로 보인다.그러나 원자재 가격이 낮기 때문에 제철소의 가격은 이미 인하되었다.
Standardize production.
However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.

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， 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.
Copper tube is a kind of nonferrous metal tube， which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity， and is solid and corrosion resistant. It will not crack when compared with the ambient temperature， heat supply pipe and refrigeration pipe in all residential commercial houses.

후난 성전망이 밝고 자원이 부족해 일부 제철소는 당분간 주문을 받지 않는다고 한다.랴오닝의 제철소는 강재를 구매하려는 열정을 증가시켰다.제철소의 납품이 양호하고 원자재 가격이 올라 철광석 가격이 올랐다.제철소는 철강 생산에 대한 열의가 높아 주철 자원이 많지 않고 가격도 올랐다.당산의 일부 강철공장은 소량의 강재를 구매하여 제련에 사용하기 시작하였는데 대다수 강철공장은 여전히 관망하고있다.원가가 증가하고 수요가 점차 방출되는 배경하에서 생철시장은 량호한 모습을 보이고있으며 단시일내에 계속 강하게 운행될것으로 예상된다.
At present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.
