In order to reduce the Al2O3 inclusions in 50Cr5MoV roller steel produced by EBT-LF-VD-VC process in a steelmaking plant, the LF refining slag was optimized and the influence of optimized slags with different w(CaO)/w(Al2O3) ratios on reducing inclusions were investigated in the laboratory. The results showed that, when w(CaO)=50-55%、w(Al2O3)=25-30% and w(CaO)/w(Al2O3)=1.5-2.0,this optimized slag can not only reduce massive Al2O3 come from aluminium deoxidation,but also change the remain into plastic CaO-MgO-Al2O3 spherical compound inclusions with 1-5μm diameter, the harm on the performance of the steel was minimized.
