The slag foaming behavior caused by the reaction between FeO containing slag and hot metal was investigated for the CaO-SiO2-Al2O3-P2O5-TiO2-MnO-MgO-CaF2 system. The peak of slag foaming height was observed when (CaO)/(SiO2) was around 1.2 and the peak value of (CaO)/(SiO2) became slightly large with the increase in temperature and the CaF2 mixing ratio. In the high (CaO)/(SiO2) region, the slag foaming height increased with the increase in temperature and the CaF2 mixing ratio.
Under this experimental condition, the inverse proportional relationship between the slag viscosity and the slag foaming height was found but no significant influence of P2O5 was observed. In the solid and liquid coexisting region, slag foaming height increased with the increase in liquid fraction.
