これらの要素を考慮して，月以来，ますます多くの鉄鋼工場が生産を停止し，呉州の生産量も制限されている.西安と唐山の暖房シーズンが早まった.また，生産制限を正式に実施する.quot；+&；quot；鉄鋼企業の月日以降の都市暖房シーズンは，将来的に鉄鉱石需要がさらに悪化する可能性がある.製鉄所の鉄鉱石在庫は相対的に高く，さらに在庫を補充する意欲は強くない.供給の面では，第半期は通常，輸入鉱石の出荷のピークである.環境保護のため，国内鉱山の生産量は減少したが，短期鉄鉱石市場は上昇動力に乏しい可能性がある.
安全で信頼性が高い：銅管は金属管と非金属管の利点を結合している.プラスチック管よりも硬く，通常の金属の高い強度を持つ（冷抜銅管の強度は同じ硬度を持つ鋼管に相当するess）；それは普通の金属よりも曲げやすく，良好な靭性と高い延性を持ち，優れた耐振動，耐衝撃，耐凍結膨張財産を持っている.
深セン市データの整理をする.
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，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.
ノツェAt present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.
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， and most of the downstream prices are asked，深セン市316 Lステンレスパイプ， 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.
**の新データによると，年月，中国，中国の鉄鉱石輸入***は億トンの大台を突破し，億万トンに達し過去 高を更新した.月～月，中国&# ;米国の鉄鉱石輸入量は%増の億万トンで，年間輸入量は億トンを超える見通しだ.しかし国慶節後の輸入鉱石の出荷量を見ると，急速に低下しているため鉄鉱石価格の上昇に伴い，鉄鉱石価格指数は時ドルを割り込み輸入鉱石の出荷意欲を低下させた.また，環境保護検査がさらに厳しくなり，部の国内鉱山の供給に大きな影響が出ている.現在，国内鉱山の稼働率は前のピークよりポイント低く，将来的にはさらに低下する可能性がある.

今日は開場します.梓潼派先物は横ばいだったが，全体の市場は停止した.その後，市場の心理状態はあまり変わらなかったケント.価格は安定しているが，部の規格は協議が必要で，協議の範囲は-元前後である.市場の全体的なリズムは安定していて冷淡である.冬中期，東北地方全体の市場は伝統的な閑散期に入り，全体の市場の収束は力がない.すべての会社が商品を販売している.在庫整理のため，すべての建設現場が閉鎖されている.低温による輸送圧力を除いて，市場は惨憺たるものだった.

In the middle and late ten days，深セン市低合金板， 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 traders had no desire to increase prices， 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， and the continuous rise of inventory led to the empty market mentality.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way not only is the copper surface serious， 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.
After : on October ， continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down， and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The citys steel， coking， electric power， cement， the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan， and the purchase of iron ore may still maintain a small amount of prudence. In addition， due to the influence of industrial users "coal to gas"， the support of raw materials is weak.
検査の結果重点分野の赤銅在庫は上昇を続けているが，全体的な圧力は大きくない.現在の主要配送センターの全体的な在庫状況を見ると，Wu，江陰楽従，在庫レベルは比較的温和を維持し，市場の圧力は相対的に小さい.Wu&# ;データによると，月日現在，呉市中厚板の総在庫量，anは万トンに近く，毎週トン増加している.月下旬には，年内に万トン減少し，春節後の 高水準から万トン低下し，週連続で上昇した.ovについて言えば数は，比較的穏やかなレベルに保たれていると言うべきだ.

Red copper inventory in key areas has risen continuously， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， Jiangyin and Lecong， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market， according to the data， as of May ， the total inventory of medium and thick plates in Wuan was close to tons increasing by tons on a weekly basis. In late April， it reached tons lower in the year， down tons from the high level after the Spring Festival， and rose for three consecutive weeks. In terms of the ovquantity， it should be said to maintain a relatively moderate level.
深セン市The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special， it is a copper material produced by using nanotechnology， and copper ions can be separated by conductivity， so that copper tubes can be produced with the separated copper ions. This method is very complex， so only advanced foreign countries can use this production method.
Advantages of red copper tube Durability: copper has stable chemical properties， integrating cold resistance， heat resistance， pressure resistance， corrosion resistance and fire resistance， and can be used in different environments for a long time.
