Abstract

Crystallization temperature of mold powder was measured by DTA. The effects of R, Na2CO3 content, CaF2 content, Al2O3 content and MgO content on crystallization temperature were determined. Via nonlinear programming, crystallization characteristics of mold powder could be optimized and predicted accurately. Crystallization temperature increased with increasing R, BI, Na2CO3 content, CaF2 content, MgO content and decreasing Al2O3 content.

Key words
