Abstract The change of basicity of sinter will have some influence on its yield, quality, metallurgical property and economic and technical index of blast furnace. The relationship between the basicity of sinter and sinter yield, yield of the blast furnace as well as coke ratio effect was compared, and the influence of sinter basicity change on the sinter yield, utilization coefficient and metallurgical properties of correspondence was tested. When the basicity of sinter with high silicon in Jiuquan Steel is within 1.6-1.9 , the metallurgical properties and various indexes are better. The utilization coefficient increases with the increase of basicity. Within the basicity interval and reducing the sinter basicity, the sinter and blast furnace grade can be improved, and the cost of pig iron can be reduced.
