Mechanism of Fractional Melting in the Splashed Coating on BOF Lining

With the self-made equipment, the behavior of the splashed slag coating was studied by the thermo-simulation. The influence of TFe, basicity and heating rate of slag on the occurrence of fractional melting was investigated. Furthermore, the composition variation of slag in different stages of the heating process was also discussed, and the mechanism of fractional melting was explained. In addition,the exploitation of this phenomenon in practice was also discussed.
