今日の朝盤，国内の銅棒の価格は下落した.Lange Steelの監視データによると，中国の主要都市の*ミリ熱間圧延帯鋼の平均価格は元で，昨日より元下がった.先物価格は変動し，現物市場のメーカーの価格は今日少し下がった.フィードバックによると，主流メーカー，今日は価格が下がった.
カジャン高い溶接温度により，同時に応力腐食に対する感受性も増加した.
In consideration of the above factors， more and more steel plants have stopped production since October and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises，カジャンどうぼう， 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.

管片価格の調整と引き下げは，主に環境保護の生産制限と温度と天候への需要が弱いためである. 近では，端末の需要も気温の急降下で萎縮し，弱い揺れを引き起こしている.滄州の地元貿易商とのコミュニケーションによると，先週の様々な朗報により，過去週間の滄州熱膨張管の出荷量が増加し，閑散期にはさらに良くなり，部の規格の出荷量も改善された.しかし，中小型パイプライン市場の取引雰囲気は依然として冷淡で，需要は徐々に鈍化している.以上のことから， 近の滄州シームレス鋼管市場の価格は安定して弱体化する見通しだ.
The application of copper tube The copper tube is generally used in the heat exchange equipment， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition the copper pipe is relatively firm， unlike other metals， which are easily corroded， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， but it is not recommended to apply oil for preservation.

生産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.
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.

Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe characterized by light weight， good thermal conductivity high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?
オファーThe hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， the hard copper tube is generally straight.
Avoid discoloration of coil surface due to pollution， and control the composition of auxiliary materials such as lubricating oil and cleaning agent. The supplier is required to provide technical performance indicators such as viscosity， flash point， and the third-party test report of elements harmful to copper tubes. In the rewinding process， strengthen the cleaning of the copper tube surface to reduce the residue of lubricating oil on the copper tube surface.
Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher，カジャン310 sステンレスシームレス管， and most of the downstream prices are asked， and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.
