摘　　要：应用软件成功的对计算机数值模拟及工艺优化的研究、铸钢过程的流场进行了数值模拟,对传统浇注系统和改进后的浇注系统分别进行了模拟分析,结果表明传统浇注系统浇注过程中容易使钢水发生紊流状充型,使铸件表面和内部产生大量的气孔。而改进后的浇注系统不仅使钢水充型平稳,而且实际生产的铸件表面和内部均没有气孔产生。The following cast processes was simulated and optimized using front-end casting filling course has been simulated using numerical simulation technology.The comparative study of simulation of tradition gating system.And improved gating system indicate that tradition gating system has turbulent form filling in molten steel,a large number of gas cavity made in surface and inside of casting.When using improved gating system,not only molten steel fills steady but also there is no gas cavity of casting surface and inside of product.
