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.

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.

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， dilute them to the total volume， stir them to make the solution even， cool them to room temperature， put a large amount of iron filings in the solution， 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， 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， due to the amount of oil contamination light and heavy rust， 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， etc. Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe electrolytic degreasing 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， 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， whichtly used for monomer and irregular shaped components. High pressure hot water degreasing: without degreasing agent， heat the deionized water to ℃， 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: 얼마예요?요약하면， 중장기 정책과 대환경 및 선양의 현재 재고 수준에 근거하여 동북지역 시장은 보편적으로 비관적이다.구리 배출의 낮은 재고 수준은 전체 시장을 동력이 부족하게 한다.본 시의 동봉시장은 올해 이미 멈추어 단기와 중기 내에 개선하기 어렵다.총체적으로 볼 때 래일 심양의 동봉의 시장가격은 안정될수 있다. 월 일 시 이후， 철정판자 [] 호 문건에 규정된 생산 중단 제한 조치를 계속 집행한다.전 시 강철기업의 습법탈황소결기， 세로로는 전부 페쇄하고 반건법탈황소결기는 계속 % 페쇄한다.차량의 통행그림.항구에 차량을 모아 운송하는 것은 항구 구역에 출입하는 것을 금지한다.도시 & #;철강， 코크스화， 시멘트， 화학공업 등 중점 차량 기업은 차량을 공장 구역에 출입할 수 없다.월 일 시 이후， 상술한 업계 자동차 기업은 % 의 오봉 배출 감소 조치를 실시할 것이다.당산 소결분의 하루 평균 소비는 만 위안 이상이 될 것으로 예상되며， 철광석 구매는 여전히 소량의 신중을 유지할 수 있다.또한 산업 사용자의 영향으로amp；quot；석탄 가스;“；，코크스가 최근 약세를 보이고 있다.따라서 제철소 생산에 있어서 원자재의 지지가 약하다. 오늘날 벽돌의 가격은 높아졌다 낮아졌다 한다.현재， 강흠열간 압연은 위안， 연주 위안은 위안， 동방열간 위안은 위안， 노력열간 압연은 위안은 위안， 천강열간 압연은 위안 하락한다안강은 원 하락하여 월 중순에 생산을 중지하였고 위강열연은 원으로 원 상승하였으며 련주 원으로 원 상승하였고 회강 원으로 원 상승하였으며 중천 원， 장강 원， 릉강 원이였다.

At present， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.
