Calculation of interface heat transfer coefficient between casting aluminum and H13 permanent mould

Interfacial heat transfer coefficient is an important boundary condition of casting process simulation, however, there is no accurate criterions for its value with relatively complicated calculation methods. In order to solve this problem, commercial simulation software for solving interface heat transfer coefficient was propsoed. Casting solidification temperature curves were measured, and the inverse module of ProCAST was used to calculate interfacial heat transfer coefficient between AC4B aluminum and H13 permanent mold. The results show that the interface heat transfer coefficient can be set to a function of temperature, and the commercial software to calculate interface heat transfer coefficient can meet project requirement.
