Аннотация
In selecting the best chemical composition of slag melts, it is expedient to take account of their viscosity and electrical conductivity, which are structure-sensitive properties. The viscosity and electrical conductivity of blast-furnace slag are studied experimentally. To permit correct selection of the slag conditions in the blast furnace, a parameter is proposed for assessing the relation between the structural particles of the melt: the heterogenization temperature, which takes account of the viscosity and electrical conductivity of the slag melts. The discharge temperature of the slag from blast furnace 8 at PJSC ArcelorMittal Kryvyi Rih is measured. Comparison of the actual discharge temperature of the slag and the calculated heterogenization temperature for blast furnace 8 permits identification of the optimal slag basicity (CaO/SiO2).
