Effect of Effective Concentration of High Melting Point Phases in RH Refining on Slag Sticking
RH精炼渣高熔点相作用浓度对粘渣的影响

To avoid crystallization of high melting point phases in refining slag,such as MgO-Al2O3 and FeO-Al2O3,during RH refining process,a calculation model of effective mass concentration for CaO-SiO2-MgO-Al2O3-MnO-FeO-CaF2 slag system was established based on the coexistence theory of slag structure,and the influences of slag components on effective concentrations of high melting point phases were studied.The results show that when slag basicity is more than 4,CaO/Al2O3 between 1.5 and 2.0,MgO content about 10%,...
