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.
동관 지온의 장점과 적용 범위는 현재 지온은 편안한 난방 방식일 뿐만 아니라 현대 생활의 질의 상징이기도 하다.갈수록 많은 주택， 공공건축， 체육시설， 공업시설 등 장소에서 지온라디에이터를 사용하기 시작하는데 이는 지온의 중요한 구성부분이다.구리의 내식성 때문에 많은 곳에서 구리 파이프를 라디에이터의 주요 재료로 선택한다.
조정.In general， iron wire can be used for dredging. When the blockage is serious， corrosive substances shall be used to corrode the blockage before corresponding cleaning.
구리 자체의 특성으로， 환경 습도가 높은 곳에서는 녹이 슬고 부식되기 쉽다.습도우리가 자주 사용하는 경우 문제가 더 적지만 오래 두면 구리가 손상됩니다.많은 사람들이 구리 표면을 어떻게 처리하는지 모릅니까?이제 직원이 답변해 드리겠습니다.
클 로 디 움안정성: 구리 파이프는 금속 파이프와 비금속 파이프의 장점을 결합합니다.그것은 플라스틱 파이프보다 더 단단하고， 일반 금속의 고강도를 가지고 있다 (동관을 냉발시키는 강도는 같은 경도를 가진 강관과 같다ess）；그것은 일반 금속보다 쉽게 구부러지고 강인성과 높은 확장성을 가지고 있으며 진동， 충격 및 동팽창에 강한 재산을 가지고 있습니다.
Disadvantages: low output high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation， which is the development direction of copper tube industry in the future.
자재 및 총 비용， 안정성 및 성능 및 유지 보수 비용 절감
또 다른 집산지인 강음시장에서 현재 유통단계의 전체 재고는 약 만 톤으로 정상 수준보다 약간 낮다.이번 주 초 강음 가격과 북방 가격 간의 가격 격차도 약간 낮은 유통 재고에 대응했다.그러나 제철소 정책항을 보면， 남강， 항윤， 다다 등 전체 생산 상황은 비교적 정상이며， the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately， so that dust and dirt will not pollute the capillary gap.
신용 경영When stacking， it shall be stacked reasonably and placed first.
Advantages: good quality， fine structure， high density， large bending deformation， suitable for frequent cold and heat exchange， large temperature difference in working environment， and large size copper tube can be produced.
동관은 일종의 비철금속관으로서 압제하고 늘어나는 무봉관이다.동관은 열전도성이 뛰어나고 견고하며 부식에 강하다.환경 온도에 비해 갈라지지 않기 때문에 모든 주택 분양주택에 수도관， 난방관， 냉동관을 설치하는 것이 현대 하청업체의 우선순위가 되었다.
Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， public buildings， sports facilities， 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.
상세 한 상황.When placing， they should be stored separately according to the different components， and should not be mixed together. The copper surface may have electrolytes， so it will react， especially with other materials such as rubber， which has a large impact.
For the production and processing of sculpted copper tubes， the sheet metal shall be first opened in the sheet metal workshop according to the dimensions shown in the drawings， which is commonly referred to as opening. Then cut the corners of these open sheets according to the height of the edge， and then use the bending machine to form the edge according to the drawing forming diagram. The shaped copper pipe shall also be installed with reinforcing ribs as required，조정.알루미늄 청동판， and the four corners of the shaped plate shall be welded well. The welded parts shall be sent to the grinding workshop， and the spraying surface shall be polished and the welding interface shall be polished and leveled. The polished modeling copper pipe is then sent to the spraying workshop for processing. Before spraying the surface of the sculpted copper pipe shall be chrome treated and the process hole shall be drilled， so as to ensure that the sculpted copper pipe can be hung on the spraying line well， and the painting can be smooth without flow marks， and the color is consistent without color difference. After that， according to customer demand， the qualified products are pasted with protective film and bound with bubble film or wooden box.
용접 공구의 드라이어는 열이 지나치게 집중되지 않도록 너무 작아서는 안 된다.

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， copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material， and then the material is purified to produce copper tube materials.
