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，크 리 스 틴 햄6061 알루미늄 바， 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， and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages: 낮은 생산 비용과 높은 생산성.
적동 재고는 지속적인 하락세를 끝낼 수 있다.철강 기업의 생산 제한 강도가 높아지고 수요 압력이 커짐에 따라 철광석 항구의 재고의 지속적인 감소는 끝날 수 있다.또한 **의 최신 통계에 따르면 제철소의 철광석 수입 가용일수는 일로 국경절 전보다 하루 줄어 사상 최고치를 기록했다.제철소는 현재 철광석 재고가 기본적으로 생산 요구를 만족시킨다고 밝혔다.향후 감산 및년 월말까지 산동성은 이미 만톤의 생철과 만톤의 조강의 생산능력과잉문제를 해결했으며 모든 생산능력제거설비는 이미 페쇄되고 퇴출되였다.월 일， 한단시발전개혁위원회는"년 한단시 과잉철강생산능력제거계획"을 발표했다.통계수치가 보여준데 따르면 년 한단의 제철능력은 만톤이고 제강능력은 만톤이다.

현재의 전체 가격차를 감안할 때， 오늘 현지 동봉 가격은 계속 높은 수준으로 상승하고 있지만， 화동 지역 이외의 지역은 뚜렷한 후속 추세가 나타나지 않고 있으며， 현지 가격은 여전히 동북과 화중 지역과의 가격차의 우세를 가지고 있다.생산 제한의 영향으로 현지의 후속 상품량이 비교적 적기 때문에， 현지의 재고 압력은 더욱 낮아질 것이며， 동봉 가격의 지탱은 여전히 강하다.그러나 현재 국내 부동산 통제는 여전히 강화되고 있다.시장 & # ;미래의 수요에 대한 시장의 예상이 약화되고 있습니다.오늘 심양 동봉의 시장 가격이 안정되어 출하량이 좋지 않다.

Four in one formula and process conditions Preparation of solution Take formula as an example: mix the calculated amount of water for zinc oxide into a paste， slowly add it into the calculated amount of phosphoric acid under stirring until it is completely dissolved， then add zinc nitrate and tartaric acid， dilute it with water to / of the total volume， add sodium alkosulfonate and OP emulsion， and stir to make it completely dissolved. Then add chromium dihydrogen phosphate dissolved in dilute phosphoric acid， and add titanium sulfate. After all materials are added， dilute them to the total volume， stir them to make the solution even， cool them to room temperature， and soak them for - days to make them contain enough ferrous ions. When the content of ferrous ion reaches above g/L， adjust the free acidity and total acidity of the solution to the specified value， and then the solution can be used at elevated temperature. When the ferrous ion reaches the above value， the phosphating speed is fast， the solution is stable， and the phosphating film is fine and dense. During operation， attention shall be paid to controlling the temperature. If the temperature is higher than ℃， the degreasing technology of degreased copper pipe. How to make degreased copper pipe? The process flow of degreased copper tube? What are the characteristics of degreased copper tubes? Use of degreased copper tube? There are too many questions. Lets solve them at once. Everyone knows the copper tube. Nitrate reacts easily. The heater should be installed on the two walls of the tank， not on the bottom of the tank， to prevent local overheating. Stainless steel pipe or iron pipe should be used for heater， and lead pipe or copper pipe should not be used to avoid contamination of solution by impurities. What is degreased copper pipipe? "The advantages of degreased copper pipes comprehensive treatment of grease， rust removal， phosphating and passivation are described. This comprehensive treatment process can simplify the process， reduce the work area， save equipment costs， shorten working hours， improve labor productivity and reduce costs. This method can only be used in the occasions where the requirements for coating quality are not high.However in actual production， light and heavy rust due to the amount of oil contamination， the consumption rate of each component in the solution is different， so attention should be paid to adjustment and control to maintain its due role. What is the degreasing copper tube? "I have roughly known the degreasing methods of degreasing copper tubes: solvent degreasing， alkali degreasing， ultrasonic degreasing， high pressure hot water degreasing， electrolytic degreasing， etc. Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe， collect it together into a container， volatilize， collect and reuse the volatile solvent， and separate the pollutants from the circulation system. This method was used in the early stage， which has problems such as low cleaning efficiency， difficult maintenance， and environmental pollution. In recent years， many kinds of surfactants have been developed. The lipophilic group of surfactants can help to dissolve oil in water to realize degreasing. Alkali degreasing: Alkali degreasing is a complex chemical physical process. In addition to saponification reaction， there are sometimes emulsion reaction and adsorption reaction. Typical saponification reaction formula is as follows: RCOOH+NaOHRCOONa+HO At present industrial degreasers are composite reagents， whichtly used for monomer and irregular shaped components. High pressure hot water degreasing: without degreasing agent and the solution temperature is ℃. Ultrasonic degreasing: ultrasonic degreasing is to degrease the upper and lower surfaces of red copper pipes by using ultrasonic to generate high-speed vibration， and spray it directly to the surface of red copper pipe for cleaning under the pressure of about bar. Electrolytic degreasing: electrolytic degreasing， using the red copper tube as the cathode to generate H， which will scour the oil stain on the surface of the red copper tube; The O generated by the anode is in atomic state and has strong oxidation capacity， which can improve the degreasing effect. Therefore， the problem that alkali spraying and brushing cannot fully contact the micro concave part of the surface is solved. Generally， the cleaning effect of alkali degreaser spraying or high-pressure hot water degreasing plus brushing can meet the requirements of most users. If there are special requirements， multiple methods can be used together. According to practical experience， the degreasing effect of various degreasing methods (one side of the copper tube) is as follows: alkali degreaser spray plus brushing: mg/m alkali degreaser brushing plus electrolytic degreasing: mg/m ultrasonic wave: mg/m high-pressure hot water degreasing: 시장.만약 당신이 장기적으로 이런 상황을 피하고 싶다면， 당신은 둔화 처리를 선택할 수 있다.이렇게 하면 구리 표면이 심할 뿐만 아니라 정상적인 상태에서는 청결할 수 있지만 초음파 처리와 침포 처리 후 년 이상 공기 중에 유지하는 것은 큰 문제가 아니기 때문에 이런 효과가 매우 좋다. When stacking， the expansion coefficient is the same， the cost of the floor heating system is higher. 제품 라인Red 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. Advantages: low investment cost， low production cost， high output and low price. It is said that due to the optimistic future and tight resources， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， the pig iron market is performing well and is expected to continue to operate strongly in the short term. 크 리 스 틴 햄Disadvantages of copper pipe As far as copper pipe is concerned， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level. If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， but it is not recommended to apply oil for preservation. 당산강판이 지난 주말에 대폭 상승하여 일부 북방도시의 강철공장이 생산제한을 실시하였고 일부 국내경제수치가 다소 개선되였는데 이는 제조업체의 신심을 진작시켰다.믿음오늘날 강재 가격이 보편적으로 상승하고 있다.그러나 회의가 다가오고 태풍으로 인한 남쪽의 비가 내리면서 하류 공사장의 공사 진도가 영향을 받아 지속적인 수요에 불리하다.고현물 가격 거래이 지역 시장의 평가 범위는 제한되어 있으며， 기업은 단기간에 유연하게 경영할 수 있으며 선적 거래는 * * * 이다.
