Melting behavior of mold powder is very important for continuous casting operation and quality of steel. In this experimental study, the shrinking behavior of mold powder was measured by thermo-mechanical analysis in order to investigate the melting behavior of mold power.
Thermodynamic calculation of the liquid fraction in the mold powder appears to show reasonable agreement with thermo-mechanical analysis data. Then, it may be concluded that thermo-mechanical analysis enables us to give useful information about the melting behavior of mold powder. The results of the thermo-mechanical analysis are summerized as follows;
Fluorite is considered to be better fluorite source than sodium fluoride, sodium fluoride is better than soda ash as Na2O source and silica powder has a superiority over diatomaceous earth as SiO2 source.
