本文通过国内外炼铁企业之间的对比,查明了我国在降低高炉综合焦比方面存在的潜力,提出了通过改善操作和简单技措在短期内就能实现的,以及需要通过技术改造方能实现的降低综合焦比的两种措施,并认为实施这些措施后将改变几年来炼铁工序能耗的徘徊局面。此外,对我国高炉鼓风消耗高的原因和降低风耗的措施,以及回收二次能源的问题进行了讨论。 Through comparing the iron and steel enterprises at home and abroad, this paper finds out the potential of our country in reducing the comprehensive coke ratio of the blast furnace, puts forward some suggestions that can be realized in the short term by improving the operation and the simple technical measures, Can achieve two measures to reduce the overall coke ratio, and that the implementation of these measures will change years of energy consumption in the iron-making process of hovering. In addition, the reasons for the high blast furnace blast consumption in our country, the measures to reduce the wind power consumption and the recovery of secondary energy were discussed.
