EllebluAlloy steelInconsistent views on the industry outlook

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.When stacking, it shall be stacked reasonably and placed first.Elleblu,If the environment is wet, it will aggravate the corrosion of copper pipes. Oxygen in water causes corrosion.Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.KiljuOverview 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?In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun, etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.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 * * * * , * * * 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, and the closing was flat.

Among the three production methods of copper tube, the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material,Elleblu12CR1MOV alloy plate,Elleblu5052 aluminum bar, the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time, but also has a mature technology, which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.When the purity of pure copper is higher, the corrosion resistance is better. Copper pipes processed with recycled copper are easy to cause corrosion due to impurities inside. (I) Problems that should be noted in copper pipe welding are generally %. % % or % silver electrode shall have good fluidity and be assisted by flux. The flux used shall be a flexible mixture or powder, with carbonization flame for copper pipe welding.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 * * * * , * * * , 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, and the closing was flat.Quotation sheet,The price of pig iron market rose by - yuan this week, and the transaction was fair. With the increase of coke price, Henan, Shandong and other regions has increased. In addition, with the gradual release of downstream demand,Elleblu310s stainless steel pipe, 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.It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.In consideration of the above factors, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; 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.

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 it was reported that the deal was very poor, which led to the price being s table for the next two days. Until Wednesday, due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving, Xinji rose yuan on the rd; For the future market the off-season is coming, the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, 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.Word of mouth recommendation,The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.When the copper tube is heated and the flux melts into liquid, place the preheated electrode on the welding point immediately. As soon as the electrode begins to melt, move the flame nozzle back and forth until the solder flows into the gap between the two tubese the flame, let the solder contact the welding point, and then remove it after a few seconds. If it is suspected or found that there is still a gap between the two pipes. It can be heated again to make the flame nozzle move continuously at two points. A small amount of solder can be added.It is mainly used to manufacture electrical devices such as generators, buses, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass, bronze and white copper. Pure copper plate is a purplish red metal, commonly known as & quot; copper plate& quot;, & amp; quot; red copper plate& quot; or & quot; red copper plate& quot;.Elleblu,[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean, because it will affect the clean interface and result in poor welding effect.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 * * * * , * * * , 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, and the closing was flat.In addition, it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures, so copper pipes need to be selected for many times in other places.
