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.
Disadvantages: low output， high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation，클 라 스 노 달2205 스테인리스 강판， which is the development direction of copper tube industry in the future.
클 라 스 노 달이러한 문제를 해결하기 위해 실리콘을 함유한 용접사는 일반적으로 용접에 사용되는데， 실리콘은 용접지 표면에 촘촘한 실리콘 막을 형성하기 때문에 아연의 증발을 방해하고 수소의 침입을 방지할 수 있다.
If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， high production cost and high price are its biggest disadvantages. Compared with other pipe fittings， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.
According to * * new data， in September ， Chinas imported iron ore * * * broke through the million ton mark， reaching million tons， a record high; From January to September， Chinas 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.

시장가 격전망이 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.
For small diameter pipes， when using filler metal， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments， sliding bearings， molds， pumps etc.
The market price of Zhengzhou copper bars is basically stable， and the shipment is not good. In terms of tube blank: today， Shandong Luli tube blank slightly reduced by yuan， the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season， traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory， and there is no large replenishment plan. The demand is sluggish and the market price of Zhengzhou copper bar is expected to be stable and declining.

자산.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，클 라 스 노 달12Cr1MoV 합금 강판， the market price of Shenyang copper bars may be stable tomorrow.
In order to solve these problems， silicon containing welding wires are commonly used in welding， because silicon will form a layer of dense silicon film on the surface of the molten pool， which will hinder the evaporation of zinc and prevent the invasion of hydrogen.

클 라 스 노 달To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
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， 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.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way， it can be cleaned under normal circumstances， but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment， so this effect is very good.
