Abstract

Abstract

The melting temperature and viscosity of Al₂O₃-CaO base pre-molten refining slag containing SrO was studied by means of quadratic orthogonally regression. A mathematical model having high significance was founded. The effects of single factor and two factors on the physical properties of refining slag were discussed. The optimal value of each composition is respectively 8%SiO₂,7%MgO,6%SrO,5%CaF₂,Al₂O₃/CaO=0.8, and this result is a theoretical support for further study.
