Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， the available days of imported iron ore of steel mills are days， which is one day lower than that before the National Day，全国産業職業訓練機関60 SI 2 MN合金丸鋼， and is on the high side of history. The steel mill said that at present， the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction the steel mill is not willing to replenish the inventory.
In the middle and late ten days， although there were good news such as the rise of futures and the increase of production restriction policy in Wuan region， due to the high inventory level， most of them had shipped goods， and spot prices lacked motivation to rise. The market inventory rose significantly. At that time， the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market，水の腐食ピットは深くなる.
Four of the five major application fields of copper plate， pipe fittings and decorative devices in the construction industry.
フルティジャールThree of the five major application fields of copper plate，全国産業職業訓練機関ステンレスコイル， 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.
長期的にこのような状況を回避したい場合は鈍化処理を選択することができます.これにより，銅表面が深刻であるだけでなく，通常の場合は洗浄することができるが，超音波処理や浸漬処理後，年以上空気中に保持することは大きな問題ではないため，この効果は非常に優れている.
通常は酸素アセチレンをガス源として用い，液化石油ガス溶接工具を用いて加熱する.溶接工具の溶接トーチは継手に面して，継手全体を連続的に加熱しなければならない.これにより，過度な局所加熱が回避される.
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， which is the development direction of copper tube industry in the future.
銅管の表面を制御する際には，夏の銅管の貯蔵と輸送にも注意しなければならない.
The simplest way is to use copper cleaner. Brass，全国産業職業訓練機関どうぼう， bronze， etc. can be used. Oil stains， fingerprints， oxide layers， etc. on the surface can be cleaned with copper cleaner first.
入札を募る銅板，銅棒，銅管のつの主要な応用分野のうちつ：銅は建築業で各種のパイプ，パイプ，装飾装置として使用されている.
以上のように，中長期政策と大環境，および瀋陽の現在の在庫水準に基づいて，東北地区市場は般的に悲観的である.銅排泄物の低在庫レベルは市場全体に動力を欠いている.当市の銅棒市場は今年はすでに停止しており短期と中期的に改善するのは難しい.全体的に見ると，明日の瀋陽銅棒の市場価格は安定するかもしれない.
月日，滄州銅棒市場の価格は安定している.Lange鉄鋼会社の監視データによると，sクラウドビジネスプラットフォーム，臨沂生産の* mm冷抜鋼市場価格は元，建龍* mm市場価格は元，元化* mm価格は元，アルゴンエネルギー* mm市場価格は元，包鋼* mm市場価格は元，巨能熱膨張* mmの市場価格は元.
方，製鉄所では，製鉄所のロック価格が下落しており，受注状況は芳しくない.この製鉄所の生産能力利用率は低いが，市場は依然として供給過剰である.製鉄所の在庫と現物在庫が上昇しているそのため，市場価格は大幅に下落した.その後，先物市場は反発し，現物価格も上昇した.瞬にして大量の取引が発生した.しかし，ブラック先物の下落に伴い，市場の取引量は大幅に縮小した.また，在庫圧力が大きく，貿易商は低価格で出荷し，現物価格は下落に耐えた.中厚板の落下防止能力が高いため，落下幅と速度はねじ山より小さい.
インストール条件Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
As theation effect of copper material on the agent is weak， the dissolved oxygen and air bubbles in it will corrode it.
銅管の卓越した性能を持つ銅管は，現代の請負業者がすべての住宅商業住宅に水道管暖房，冷却管を設置するための適切な選択となるような和の特性を持っている.
全国産業職業訓練機関Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
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 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.
In the morning trading today， the price of domestic copper bar fell.
