摘　　要：利用procast软件对大型轧钢机机架铸件的充型、凝固过程中流场和温度场进行了模拟分析,能够较好地预测铸造过程中产生的浇不足、冷隔、夹渣、缩孔缩松等缺陷,为合理优化设计浇注系统,制定最佳工艺方案提供依据。借助procast软件模拟仿真,能够缩短产品试制周期约三个月,降低生产成本约20%,同时能够提高铸件材料利用率,确保铸件质量。仿真结果能够较好地反映实际生产情况。The flow field and heat transfer during the mold filling and solidification stage of the large scale mill house have been simulated and analyzed by using PROCAST software.It can well predict run-out,cold shut,slag inclusion and porosity shrinkage defects that are produced in casting process,and provide guide for optimization design of gating system and establishment of optimum foundry technology.Simulation of casting process with PROCAST can shorten the time for the cycle period of product manufacture by three months,reduce production cost 20%,improve casting material utilization and ensure the quality of castings.Simulation results by reflected well the actual production condition.
