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 quantity of * * * is relatively limited. In general， the short-term iron ore market may lack upward momentum.
El Mahalla El Kubra 마을The copper tube welding process is to radiate the copper tube bundle with excellent directivity high brightness， 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，El Mahalla El Kubra 마을304 스테인리스 강판， 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.
Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe， characterized by light weight good thermal conductivity， high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?
아일랜드Lets elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium， circulates in the copper pipe heating pipe， heats the floor， and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， high pressure resistance， relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.
용접 공구의 드라이어는 열이 지나치게 집중되지 않도록 너무 작아서는 안 된다.
용접할 때는 모세관 간격을 채우기 위해 충분한 필러 금속을 추가하기만 하면 됩니다.너무 많은 채우기 금속은 조인트 하단에만 구를 형성하거나 파이프로 유입됩니다.
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.
{} 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 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.
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， 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.

After welding， it can be annealed at ~ ℃ to prevent "self cracking" by stress.
Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
El Mahalla El Kubra 마을Later， Mexican scientists also found that copper has a . Recently， 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，El Mahalla El Kubra 마을6061 알루미늄 튜브， 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，El Mahalla El Kubra 마을12Cr1MoV 합금 강판， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， 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.
The copper tube shall be heated and welded first， and then the joint shall be heated until the heated part turns dark red. At this time， when the filler metal contacts the tube， the filler metal shall melt.
The second of the five application fields of red copper plate T， red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels， distillation pots， brewing pots， etc.
