Application and research of reverse optimization calculation of thermal physical parameters of molded sand for casting
Computer simulation is increasingly used in the existing casting technology,and the simulated thermo-physical parameters that are consistent with the field are a necessary condition for accurate sim-ulation.Therefore,through the optimization module of Magma simulation software,the thermal conductivi-ty and specific heat of the sand are adjusted,DOE experiments are designed for simulation,and the simulated temperature curves are fitted to the curves measured in the field,and the parameters used in the simulated curves are the thermophysical parameters that are consistent with the actual sand in the field.
