Abstract

In order to optimize the production process of the fused zirconia-alumina-silica material(AZS), the simulation was conducted by using the Anycasting software to study effects of the mould specific heat of SiO2 material on the system solidification time, solidification fraction, temperature gradient and solidification sequence. The results showed that: when the specific heat was more than 676 J•kg-1•k-1, the decrease of solidification time tended to be slow. When the melt at the bottom center of riser cooled down to the solidus temperature, the system solidification fraction reached 96% when the mold specific heat was less than 1352 J•kg-1•k-1. The temperature gradient increased along with the augment of SiO2 sand mold specific heat. Considering the temperature gradient at the bottom center of riser, the specific heat should be 13.52 J•kg-1•k-1-1352 J•kg-1•k-1. The riser feeding effect was the best when the specific heat was 1352 J•kg-1•k-1. The optimized mold specific heat was 1352J•kg-1•k-1.
