According to the structural characteristics and quality defects of beam castings,the casting numerical simulation technology was used to optimize and determine the parting surface,pouring system,cold iron,riser and pouring process parameters.The quality of nodulation is ensured by strict control of the ratio of charge,high temperature melting of iron liquid,low rare earth spheroidization,high barium inoculation and sulfur and oxygen inoculation with flow.The indicators of the first trial-produced beam casting basically meet the technical requirements,and the mass production after further improving the process,the casting quality meets the requirements,and the product quality is stable and consistent.
