摘　　要：针对横梁铸件的结构特点以及易出现的质量缺陷,通过铸造数值模拟技术,优化确定分型面、浇注系统、冷铁和冒口及浇注等工艺参数;严格控制炉料配比和铁液的高温熔化与低稀土球化、高钡孕育及硫氧随流孕育处理等生产过程,保证了球化质量。首件试制横梁铸件各项指标基本满足技术要求,进一步完善工艺后批量化生产,铸件质量满足要求,且产品质量稳定一致。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.
