双辊薄带不锈钢铸轧过程数值模拟

Coupled simulation on twin-roll casting stainless strip process

采用有限元法模拟了双辊铸轧不锈钢过程的流热耦合问题 ;分析了铸轧速度对熔池内流场、温度场的影响以及流场与温度场之间的相互影响 ;通过熔池内温度场及温度梯度分析了熔池内凝固的发展及其对热流密度变化的影响。此模拟结果可以为控制铸轧过程的稳定提供有效的数据。

Coupled turbulent flow, temperature fields are simulated by finite element method. The interacting between casting velocities and flow, temperature fields are also analyzed. The mechanism of the heat flux changing is explained by the temperature fields and the solidification developing of the molten field. All these can be helpful to the control of cast-rolling process.
