| Abstract: | 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. |
