摘要
利用FT Star及IDEAS软件对马钢双板轧机机架铸件的充型、凝固、冷却过程中的温度场及热应力、应变变化进行了模拟分析,为实际生产设计了合理的铸造工艺。结果表明,采用模拟软件可确定冒口、冷铁位置尺寸,控制凝固顺序,保证铸件质量。同时,采用计算机辅助铸造工艺技术可解决熔化能力不足等实际生产问题,从而为一般非专业铸造企业生产大型轧钢机架等重要铸件提供有益的借鉴。
The heat transfer and thermal strainstress evolution during the mold filling,solidification and cooling stage of the twinband mill house casting in Maanshan Iron and Steel Corporation have been simulated and analyzed using FTStar and IDEAS softwares,and the foundry technology has been designed and optimized for the practice. The results obtained show that the position and dimension of the risers and chills can be decided so as to control the solidification pattern and to assure the quality of casting by utilizing the foundry technology software. Further more, the disabilities such as insufficient melting capacity in the plant can be remedied with the assistance of the computer aided foundry technology. The study gives a referential example for the curbstone foundry enterprises to produce the large scale castings such as mill house.
