PHYSICAL-PROPERTIES OF NATURAL BLAST-FURNACE SLAGS OF VARYING BASICITY

The viscosity and fusibility of natural blast-furnace slags from the A zovstal Combine with additions of coke fines of different origin are s tudied, Carbon soot and coal-dust fuel have the greatest influence on the reduction in viscosity and fusibility, followed by coke fines from different plants, In addition, the variation in viscosity and fusibil ity of natural slags after introducing up to 8% MgO and up to 9.68% Al 2O3 is established, Fusibility diagrams of the system of synthetic sla gs CaO-MgO-SiO2-5% Al2O3-2% S-1% MnO-1% FeO-0.5% K2O with additions of coke fines, soot, and ash are plotted.
