In order to solve the problem that ZG15Cr1Mo1 steam turbine combustion cylinder steel casting is sensitive to the cooling rate of heat treatment and has a large crack tendency,The technical requirements and structural characteristics of cast steel parts were analyzed.The casting process of castings was improved by horizontal casting,increasing riser,adding cold iron and setting slag collecting runner.After reliable verification by numerical simulation analysis,production test was carried out,and qualified castings meeting the requirements were obtained.
