摘　　要：利用商业软件ANSYS对电炉熔体部分进行了模拟计算,并研究了恒功率下不同的电极插入深度对熔体的焦耳热场和温度场的影响。结果表明:随着电极插入深度的变化,靠近电极区域的焦耳热有明显的变化,而远离电极区域的焦耳热变化相对较小;温度与焦耳热分布类似,电极插入越深,熔体底部温度升高,顶部温度减小,并且靠近电极区域的温度变化更加明显。The effect of electrode immersion depth on the Joule heating field and temperature field in the melt was studied by using commercial software ANSYS.The results show that the Joule heating field has a significant change near the electrode with different electrode immersion depth,but this change is relatively smaller in the area far away from the electrode.The temperature distribution is similar to the Joule heat distribution.When electrode was immersed deeper into the electric furnace,the melt temperature increased at the bottom and decreased at the top,the change of temperature distribution near the electrode is more obvious.
