Key Words：stainless steel thin-walled rotary body casting without pattern casting simulation
Abstract：Taking the production of a single piece of 304 stainless steel thin-walled rotary body casting as a research object,during the first casting test,cracks occurred on the side wall of the rotating body casting.By analyzing the causes of cracking defects,the casting system was designed.After the improvement,ProCAST casting simulation software was used to simulate the filling,solidification process,and shrinkage and shrinkage hole defect distribution of the casting process without pattern of the stainless steel thin-walled rotary body,and the test verification by casting without pattern was performed according to the analyzed results.Cracking of sidewalls was resolved.
