摘要/Abstract

摘要： 利用有限元分析软件ANSYS求得稳定电渣重熔过程电极、渣池和钢锭系统电磁场和焦耳热场分布,并通过计算流体力学软件FLUENT模拟分析了耦合电磁场和焦耳热场的三维电渣重熔过程电极填充比0.3~0.7对电渣重熔系统温度场、速度场和电磁场的影响。结果表明,随着电极填充比的增加,速度最大值和湍动能最大值逐渐增加,但变化速率随填充比增加而下降;填充比0.3和0.5之间的最大湍动能差值约为填充比0.5和0.7之间湍动能的2倍;温度最大值随填充比不是单调变化的。

Abstract: The distribution of magnetic field and Joule heat field of electrode, slag and remelting ingot system during electroslag remelting (ESR) process is obtained by using finite element software ANSYS, and the effect of electrode filling ratio 0. 3 ~ 0. 7 in three-dimension ESR process coupling magnetic field and Joule heat field on temperature field, velocity field and magnetic field of ESR system is simulated and analyzed by using calculated fluid dynamics software FLUENT. Results show that with increasing electrode filling ratio, the max values of velocity and turbulent kinetic energy increase, but the variation ratio of velocity decreases ； the difference of max turbulent kinetic energy between electrode filling radius ratio 0. 3 and 0. 5 is as twice as that between electrode filling ratio 0. 5 and 0. 7 ； with increasing electrode filling ratio the max temperature value is not monotonous variation.
