Under the situation of raw material's quality not being guaranteed in 4# blast furnace of Han Steel,its steady condition and smooth running and high-efficiency production are realized with operation parameters being continuously optimized and low-silicon smelting adopted,and its highest operating rate reaches 2.
邯钢4#高炉在原料不太好的情况下,在确保炉况稳定顺行的基础上,不断优化操作参数并实施低硅冶炼,高炉利用系数最高达到2。
The intensification of blast furnace operation is based on quality raw materials and smooth running are put forward.
精料是高炉强化的基础 ,顺行是高炉强化的前提。
The cause of clogging on furnace wall and instable running of BF is the relatively great fluctuation of water temperature difference above the middle of bosh.
加强冷却制度管理不仅有利于高炉顺行 ,也有利于高炉生产指标的改善和经济效益的提
By implementation of Ca-treatment in the secondary refining instead of Re wire feeding into the CC mould the ratio of smooth operation in refining SM490A has been greatly raised and the elongation of the steel increased by 12% and perfect good cold bending achieved.
通过在精炼用钙处理代替在结晶器喂稀土丝的工艺 ,使SM4 90A钢的操作顺行得以很大提高 ,延伸率提高了 12 % ,冷弯完好 ,产品完全满足使用要求。
3 BF came into the end-stage production,by adoption of beneficiated burden、reasonable charging system、increasing blast temperature、furnace maintenance、scheduled gunning and so on,it not only kept BF long-term stability and improves every economic indicator,but also made a historical breakthrough in many marks at the beginning of 2006.
首钢3号高炉进入末期生产以来,通过采取精料、合理装料制度、提高风温、维护炉体、定期喷补等措施,不仅使高炉长期顺行稳定、各项经济指标不断改善,且2006年初多项指标实现了历史性的突破。
