In terms of steel billets: at :， some steel billets in Changli were reduced by ， and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China， the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore， it can be seen that at this stage， there was no unilateral market for either futures or cash， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication， Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.
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， chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October ， 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，静岡青銅板， due to the influence of industrial users "coal to gas"， the recent performance of coke is weak. Therefore， in terms of steel plant production， the support of raw materials is weak.
静岡The copper tube welding process is to radiate the copper tube bundle with excellent directivity， high strength， high monochromaticity， high coherence and other characteristics to the surface area of the workpiece to be processed. After the copper tube bundle is focused by the optical system， through the interaction between the copper tube and the object to be welded， a highly concentrated heat source area can be formed at the place to be welded in a very short time. The heat energy makes theea to be welded melt， cool and crystallize to form a solid welding spot and weld seam.
When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
グリフ座材料と総コスト，パフォーマンスを節約し，メンテナンスを節約できます.
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 market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， 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.
Save materials and total cost， and can save maintenance.

Reasons for copper pipe corrosion: Air pollution.
The copper bar market declined steadily this week， with a decline of - yuan. Due to low pig iron inventory， but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently， the steel market has been in shock and adjustment， and the merchants are unstable. Steel mills in Hebei， Tianjin and other regions have stopped producing pig iron for steelmaking. Now，静岡どうぼう， it is mainly expected to make inquiries. However， due to the lower price of raw materials， the price of iron mills has been lowered.
インストール要求Four of the five major application fields of copper plate， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.
ジャン&# ;銅管材料の利点を詳しく述べた：銅管床暖房とは熱水を熱媒体として利用し，銅管加熱管の中で循環し，床を加熱し，地面を通じて と対流伝熱の方式で床を加熱する加熱方法である.，銅管の放熱効果が速く，耐熱性が強い.高温給水の場合でも，地熱管の使用寿命は影響を受けない.銅管は金属管であり，o傷がつきにくい.そのため，漏れにくい.高温に耐え，高圧に耐え，通常のプラスチック管に比べて.銅管の床は暖かく，高温と高圧に耐えられる.寿命が長い.
Disadvantages of copper pipe As far as copper pipe is concerned， high production cost and high price are its biggest disadvantages. Compared with other pipe fittings， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.

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.
静岡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.
Copper tube is a kind of nonferrous metal tube， which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity， and is solid and corrosion resistant. It will not crack when compared with the ambient temperature， so it becomes the first choice for modern contractors to install the water pipe， heat supply pipe and refrigeration pipe in all residential commercial houses.
Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， T， oxygen free copper plate (TU， TU and high-purity vacuum oxygen free copper)， deoxidized copper plate (TUP， TUMn)， and special copper plate (arsenic copper， tellurium copper， silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere， sea water， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
