电渣熔铸过程渣池流场的模拟研究

Simulation Analysis of the Slag Pool Flow Field in the Electroslag Casting Process

电渣熔铸过程中熔渣的流动决定了熔铸体系温度场的分布以及金属熔池的形状,最终影响熔铸钢锭的质量。采用大型通用有限元分析软件ANSYS,对电渣熔铸体系渣池流场进行了模拟研究,所得结果与物理模拟实验结果完全一致。并以此研究了熔铸电流,填充比和电极端部形状对熔渣流速分布的影响,为实际生产提供了依据。

The flow of the molten slag pool determines the temperature distribution and the pool profiles in the electroslag casting process, which affects the quality of ingot casting. The flow field of the molten slag pool in the electroslag casting process was simulated by the large-scale finite element analysis software ANSYS, the result on which was completely in accordance with the physical simulation results. It was discussed that the influence on the molten slag flow field was caused by the current, the filling scale and the angle of electrode taper, which provided the scientific basis for the produce of the electroslag casting.
