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 stable 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 the market lowered the price. Market price changes， the off-season is coming Xinji rose yuan on the rd; For the future market， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
今日，ビレットの価格は高くなったり低くなったりします.現在，江鑫熱間圧延元，連続鋳造元が元下落し，東方熱間圧延元が元下落し，魯力熱間圧延元が元下落し，天鋼熱間圧延元安鋼は元下落し，月中旬に生産を停止し，威鋼熱間圧延は元上昇して元，連鋳は元上昇して元，淮鋼は元上昇して元，中天は元，長強は元，凌鋼は元だった.
バンティング般的に，針金は浚渫に用いることができる.目詰まりがひどい場合は腐食性物質を使用して目詰まりを腐食し，その後，適切な洗浄を行う必要があります.
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.
Loum**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，バンティングどうぼう，国内鉱山の稼働率は前のピークよりポイント低く， the overall market has stopped. The market mentality has not changed much sincekend. The price is stable， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter，バンティングブロンズ管， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.
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.， the price may still maintain a narrow range of shock operation pattern.
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.
The more residual chloride ions， the deeper the corrosion pit of water.
月，国内の中厚板価格は大幅に下落した.月日現在，バンティング7075アルミニウム管，主要都市の普通炭素板価格センターはに下落し，月末より元/トン下落した.今月初め，マクロ的な悪いニュースや 近のファンダメンタルズの不振の影響を受けて，市場心理は悲観的になり，部のトレーダーは低価格で出荷した.市場在庫が上昇し，在庫圧力が高く，在庫不足現象がなくなり，市場取引の雰囲気が冷淡で，需要表現は持続的に下落し，現物価格は圧力を受けて下落した.
信頼でき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.
それは優れた導電性，熱伝導性，延性と耐食性を持っている.
溶接時には，毛細管ギャップを充填するために分な充填金属を追加するだけでよい.充填金属が多すぎると，継手の底にボールが形成されたり，パイプに流れ込んだりするだけです.
見通しが楽観的で資源が逼迫しているため，鉄鉱石価格が上昇した.製鉄所は鉄鋼の生産意欲が高いため，鋳鉄資源が少なく価格も上昇した.唐山の部の製鉄所では製錬用に少量の鋼材が調達され始めており，多くの製鉄所ではまだ様子見が続いている.コスト増加と需要の逐次放出を背景に，銑鉄市場は好調で，短期的には引き続き力強い運行が見込まれている.
管理部Overview 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?
Standardized design.
Do not store too many other products， especially other acid materials and alkali materials， in the warehouse to prevent mutual reaction.
バンティング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.
For small diameter pipes， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments， sliding bearings， molds， heat exchangers， pumps， etc.
Red copper plate has ductility. Pure copper， which is as big as a drop of water， can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive ， second onlyver in common metals. But copper is much cheaper than silver， so it has become the "protagonist" of the electrical industry.
