The influences of different MgO contents in the mixed burden on the softening-melting properties of burden by high temperature simulation experiment were studied.The results indicate that with the increase of MgO content in the mixed burden,T10% and T40% increase,and the softening temperature range widens.The higher the MgO content,the greater the difference between T40% and Ts.Besides,Ts,Td and ΔTds all increase with the increase of MgO content in the mixed burden,which leads to the increase of the thickness of the melting zone.Finally,the ΔPmax and S of the softening-melting zone increase with the increase of MgO content in the mixed burden,which is not conducive to the stability of the blast furnace.
