記事の内容

Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.

It is mainly used to manufacture electrical devices such as generators, buses, cables, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass,都斛GCR 15合金丸鋼, bronze and white copper. Pure copper plate is a purplish red metal, commonly known as "copper plate" "red copper plate" or "red copper plate".

都斛When heating steel pipes, the temperature is slightly higher than when heating copper pipes.

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, Xinji rose yuan on the rd; For the future market, the off-season is coming, the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, the environmental protection inspection is becoming more and more strict, which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.

ボディティFirst of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, while the humidity should be normal. The room should be kept ventilated.

見通しが楽観的で資源が逼迫しているため,部の製鉄所ではしばらく受注しないという.遼寧省の製鉄所は鋼材購入の意欲を高めた.製鉄所の納品が好調で原材料価格が上昇したため,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,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.

Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present, the demand and cost support are weak, and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages:生産コストが低く,生産効率が高い.

しかし,唐山鋼鉄集団有限公司は現在,熱コイルの供給を増やしているという.将来的にはより多くの製鉄所が利益を追求したり,価格は依然として幅の狭い揺れの運行構造を維持する可能性がある.

Under the action of high welding temperature the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints, and also increases the sensitivity to stress corrosion.

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.

設備の修理銅管の接続堅固性が強い:銅管と銅管部品の接続が堅固である.

また,腐食されにくく,さまざまな環境に適応できます.低温と高温で正常に使用できるため,他の場所では何度も銅管を選択する必要があります.

それは優れた導電性,延性と耐食性を持っている.

遼寧省の部の鉄鋼工場は銑鉄を購入しようとしているが,現地の資源が逼迫しており,鉄鋼工場,オファーが高すぎて,需給の食い違いを招いた.江蘇,山東,山西,河北,河南などの地域では鋳鉄と球状インク鋳鉄の需要が低迷し,製鉄所の在庫圧力が高まっている.原材料価格の低下に伴い,製鉄所のオファーは低下し続けている.現在,需要とコストのサポートは弱く,プラスの上昇はありません.短期銑鉄市場は軟調で,変更は難しい.

便利で効率的ですThe material of the water separator is the same,都斛15 CrMo合金鋼板, the expansion coefficient is the same, and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe, the cost of the floor heating system is higher.

{} The excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance, which makes it a suitable choice for modern contractors to install the water pipe, heating pipe and refrigeration pipe in all residential commercial houses.

The material of the water separator is the same, the expansion coefficient is the same, and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe, the cost of the floor heating system is higher.

都斛For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, accounting for more than half of the total consumption. Used for various cables and wires red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, 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.

銅管の特徴は,都斛ステンレス溶接管,水道管,熱供給管,冷凍管を取り付けることの第選択である.

また,腐食されにくく,さまざまな環境に適応できます.低温と高温で正常に使用できるため,他の場所では何度も銅管を選択する必要があります.
