The fluidity of BF slag deteriorates as the usage proportion of the low-cost imported iron ore becomes larger,because of the higher alkali metal and TiO2 contents,therefore,it is necessary to determine the influence of alkali metal and TiO2 on BF slag fluidity.Detailed research results show that slag viscosity increases with the increase of TiO2 content,and decreases with the increase of alkali metal content.The binary basicity affects the viscosity and the melting temperature significantly.The proportion of imported iron ore containing TiO2 to toal input ore should not exceed 30%,and the composition of slag should be controlled as follows:the TiO2 content is 3.2%,the alkali metal content is 0.86%,the binary basicity is 1.05,the MgO content is 10.46%.After considering these conditions,the resulted slag fluidity can be improved.
