Abstract

The initial casting process of steel casting beam was designed by conventional method.The solidification process of initial casting was simulated by the View Cast software.The location and origination of shrinkage porosities in the initial casting process were analyzed.Based on the above analysis

through adding chilling iron and using insulating riser

the casting process was optimized and simulated again.The results show that the optimized process can fill smoothly and orderly

realizing sequential solidification and eliminating shrinkage and porosity mostly.According to the optimized process for actual production

the casting quality is improved greatly

and microstructure and mechanical properties meet the requirement.
