建立了铸件充型过程中金属液流体湍流和层流流动及凝固冷却时三维速度场和温度场数值模拟的计算方程 ;介绍了这些方程的数值求解 ,相关边界条件及凝固潜热处理方法 ;以此为基础 ,编制了三维计算、前处理、后处理程序及相关数据库 ,形成了SRIFCAST软件。本软件已成功地应用于铸造生产 ,制定了各种铸件尤其是精密铸件的铸造工艺 ,获得了优质铸件。 The numerical equations of 3D numerical simulation of velocity field and temperature field are established for turbulent flow, laminar flow and solidification cooling of molten metal in the process of casting filling. The numerical solution of these equations, the relevant boundary conditions and the latent heat treatment method are introduced. As the basis, compiled three-dimensional calculation, pre-treatment, post-processing procedures and related databases, formed SRIFCAST software. The software has been successfully applied to foundry production, developed a variety of castings, especially precision casting casting process, access to high-quality castings.
