Abstract

Liquidus temperatures of mould fluxes for casting of Ti-stabilized stainless steel were determined by differential thermal analysis (DTA) techniques in the present work. Multiple DTA curves were employed to guarantee better accuracy for liquidus temperature determination. To investigate effect of compositions change on solidification of mould fluxes during casting of Ti-stabilized stainless steel, changes of liquidus and solidus temperatures with TiO2 substitution for SiO22 in mould fluxes were studied. It was found that TiO2 substitution for SiO22 in mould fluxes would lead to decrease of liquidus temperature. Thermodynamic package FactSage was also employed to calculate the liquidus temperature of mould fluxes. The calculated results were compared with experimental data, and discrepancy between calculated and experimental liquidus temperatures was discussed.

Keywords: mould fluxes; liquidus temperature; differential thermal analysis; Ti-stabilized stainless steel; FactSage
