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.Tangshan billets rose sharply last weekend, steel mills in some northern cities implemented production restriction, 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,The storage and transportation of copper tubes in summer should also be paid attention to when controlling the surface of copper tubes.When stacking, it shall be stacked reasonably and placed first.Linz-Airport,The main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day, including * * * * ,Santa CruzRed copper tube, * * * , settlement price , trading volume , and position volume . The intraday tradg volume decreased by compared with the previous trading day and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment, there was a rebound at the bottom of the session today, but it was corrected again later, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels distillation pots, brewing pots, etc.

Insert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux,Santa Cruz6063 aluminum bar, and the joint is assembled and can be heated.And do a good job of data sorting.First of all, while the humidity should be normal. The room should be kept ventilated.management,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, the market price of Shenyang copper bars may be stable tomorrow.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 & quot; self-cleaning& quot; fluxes are generally not recommended because of their corrosivity.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.

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.demand,Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes, the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance, but also very convenient to operate. There are three production methods for copper tube, so what are the three production methods for copper tube?To prevent core problems of copper tubes, the outlet tempmperature of copper tubes should be well controlled. The cooling capacity of the annealing furnace in the cooling stage should be improved by equipping a refrigeration unit for the annealing furnace, so as to ensure that the outlet temperature of copper tubes does not exceed ℃. By controlling the outlet temperature of copper tubes, the problems of the core of coil tubes and the inner wall of the purging inlet end can be solved.To 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, 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.Santa Cruz,Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.In terms of steel billets: at :, some steel billets in Changli were reduced by , and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China, the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore, it can be seen that at this stage, there was no unilateral market for either futures or cash, and there was no definite pattern of ups and downs. According to the monitoring data of Lange Iron and Steel s cloud business platform, as of the time of publication Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton,Santa Cruz1060 aluminum bar, B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton, and that of B steel is yuan/ton; Jiyuan # yuan/ton, B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton, B steel yuan/ton.So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.
