本文对影响提升高炉喷煤比的因素进行了全面的分析,从生产实践中,实现了高利用系数、低燃料比的实践经验。为提升整体的生产率,提出了应当在优质原料以及高风温的环境下进行操作,同时还要保证大炉腹煤气量操作高炉,并不能单纯的依靠风量提升冶炼程度。并对合理喷煤比的技术进行了分析。 In this paper, a comprehensive analysis is made on the factors that affect the coal injection ratio of the blast furnace. From the practice of production, the practical experience of high utilization coefficient and low fuel ratio has been realized. In order to enhance the overall productivity, it is proposed that the operation should be carried out under the conditions of high quality raw materials and high winds, and at the same time, it is also necessary to ensure that the operation of blast furnace gas with a large amount of gas in the bosh does not depend solely on the air volume to enhance the smelting degree. And the technology of reasonable coal injection ratio was analyzed.
