Optimization of P20 small ingot casting scheme based on ProCAST

In view of defects such as shrinkage cavity and looseness in ingot, ProCAST was used to conduct multi-level simulation of casting temperature and casting speed of 50Kg P20 ingot during casting, and analyzed the quality of ingot under different casting schemes, and finally obtained the relatively optimal casting scheme. For the ingot type used in this study, the influence degree of shrinkage cavity and porosity can be effectively reduced when the selected pouring temperature is 1570 ℃ and filling time is 20 seconds. The research results provide some reference for the optimization of casting scheme in the actual production of small steel ingot.
