Abstract：The reason and measure for slag buildup on RH immerge tube under current process of Panzhihua Steel have been studied based on experimental analysis and thermodynamic calculation. After studying the matters of slag buildup on RH immerge tube, it was found that the crystallization of high melt point phase MgO·Al2O3 are main cause for slag buildup. The results of effect of refining slag compositions on slag buildup indicates that the effective measure for reduce slag buildup is to control the activities of phases with high melting point in order to decrease crystallization of it by improve slag basicity and the ratio of CaO/Al2O3, and reduce the content of MgO.
