摘　　要：为提高唐银钢铁公司高炉喷煤量,研究了烟煤配比、强化高炉喷煤操作和提高煤比、煤焦置换比等问题,得到:煤粉成分V 22%～25%,A<12%,S<0.8%;粒度-200网目以下占50%,0.074～0.15 mm占45%,0.15～0.5mm占5%。同时强化高炉喷煤操作,采取提高煤粉燃烧率,选择适宜的操作制度,提高精料水平,高炉操作调剂等措施,来提高喷煤比、煤焦置换比。Studying on the mixture ratio of soft coal, strengthening the operation of blast furnaces, raising coal rate and the coal-to-coke replacement ratio is to improve the injecting coal quantity of the blast furnaces in Tang yin Iron and Steel Company. The coal should be controlled V 22% - 25%, A 〈 12%, S 〈 0. 8%. 0. 074 - 0. 15ram is about 45% and 0. 15 - 0. 5ram is about 5%. Strengthening the operation of blast furnaces,increasing the combustion efficiency of pulverized coal, choosing the appropriate operation regulations, improving refining minerals and the measures of adjus-ting the operation of blast furnaces,raising the coal injection ratio and the coal-to-coke replacement ratio.

关 键 词：高炉喷煤 煤焦置换比 燃烧率
