Abstract

For the continuous casting of aluminum containing stainless steel, there should be a minimal amount of silica in the mold powder. It oxidizes aluminum in molten steel, allowing chemical composition to vary, and undesired inclusions to form. In mold powder, silica is important component to lower the melting point and maintain adequate viscosity. A substitute for SiO2 might be TiO2, because of its nature as an acidic compound. Although the liquidus and solidus of the system is minimum knowledge for the melting point, they have not been well established. The phase relations of the Al2O3-CaO-TiO2 system were investigated by the hot filament technique under various oxygen partial pressures. The effect of B2O3 addition to the Al2O3-CaO-TiO2 system on the liquidus and solidus was also investigated.
