Abstract: 　　Computer simulation of temperature and stress fields of ingot mold in service is one kind of new methods for construction project of ingot mold. It can indicate easy of deformational and cracking local in service. Which are important data for improving construction project of ingot mold. According to temperature and stress fields, construction project of ingot mold. According to temperature and stress fields, improved construction of ingot mold was put forward. Stresses of ingot mold with new construction decrease and distribute equilibrium. It can increase service life of ingot mold. In this paper equivalence thermal. Conductivity was put forward and replaces interface thermal exchangeable coefficient between ingot and ingot mold. Then calculation processes can be simplify.
