摘要：
The effect of tellurium addition on supersaturation observed in aluminum deoxidized liquid iron was studied at 1873 K, using CaO-Al2O3 slags in an alumina crucible. Supersaturated oxygen content for a given aluminum level decreased with the addition of tellurium as a result of lowering the interfacial energy between liquid iron and alumina and promoting the elimination of precipitated alumina by notation. Furthermore, the degree of lowering of oxygen content was found to increase with a decrease in cooling rate. Tellurium distribution ratio between liquid iron and CaO-Al2O3 slags was determined as a function of aluminum content.
