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， 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.

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 * * *.
The market opened today. Although the performance of Zitong Pai futures was modest， the overall market has stopped. The market mentality has not changed much sincekend.

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.

管理部唐山鋼片は先週末に大幅に上昇し，部の北方都市の製鉄所では生産制限が実施され，部の国内経済データが改善され，鋼材の価格は普遍的に上昇した.しかし，会議の接近や台風による南方の降雨に伴い，下流の工事現場の工事進度が影響を受け，持続的な需要に不利である.今日の高現物価格の取引は軟調で，鉄鋼価格の持続的な上昇を支えることは難しい.明日の建材市場は揺れを維持する見込みで，部の業者は値下げして商品を受け取る可能性がある.
Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， but also a symbol of modern life quality. More and more houses， public buildings， industrial facilities and other places begin to use ground heating radiator， which is an important part of ground heating. Due to the corrosion resistance of copper， copper tubes are selected as the main material of radiator in many places.

品質管理今週の銑鉄市場の価格は-元上昇し，取引は公平だった.コークス価格の上昇に伴い，山西省河南省，遼寧省，山東省などの地域の球状インク鋳鉄のコストが増加した.また，下流の需要が徐々に放出されるにつれて，製鉄所の在庫量は大きくなく，製鉄所は続々と値上げされている.山東，江蘇河北，山西の鋳鉄工場は少なく，在庫は依然として低い.コークス価格の上昇とコストの増加に伴い， and the tube is used to replace the hard one， so soft copper is widely used. Besides being in a straight line， you can also have coils and coils in the form of long advantages. When used at the connection point is long， cut according to the free length， so as to avoid leakage of copper tube brass welding. Soft copper tube requires local bending of air conditioner， refrigerator， and mechanical oil tube.pper tube Copper tube is easy to heat because of its light weight， and it can also be used normally at low temperatures.
Hygiene and health: various modifiers， additives， additives and other chemical components of plastic pipes in copper pipes.
東京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， 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.
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，東京青銅板，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，東京316 Lステンレスコイル，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.
