摘　　要：基于有限元分析原理,使用ANSYS软件对有芯感应炉感应器建立数学模型,通过模型仿真对熔沟模涡流及涡流损耗分布进行分析,对比计算两种结构熔沟模涡流损耗功率,证明了新型熔沟模的有效性。最后指出:与传统熔沟模相比,新型熔沟模起熔时电流密度更大,涡流损耗值更大,起熔功率为传统熔沟模起熔功率的20倍,能源利用率高,起熔速度更快;相同起熔功率及时间下,新型熔沟模温度上升更快;当熔沟模模壁厚度过小时,起熔温度将难以控制,易造成断沟事故,在保证熔沟模温度及防止断沟事故的条件下理想的熔沟模厚度为12~16 mm。Based on the principle of finite element analysis,the mathematical model was established by using ANSYS software,the vortex current and vortex loss distribution were analyzed through model emulation,and the effectiveness of the new pattern was proved.Finally,point out:compared with the traditional melting ditch pattern,the new melting ditch pattern had greater current density,the eddy current loss value was larger,the melting starting power was 20 times of that when using the traditional melting ditch pattern,the energy utilization rate was high,and the melting starting speed was faster,by the same melting starting power and time,the temperature rises faster when using new melting ditch pattern,when the wall thickness of the melting ditch pattern too small,the starting melting temperature would be difficult to control that easy to cause ditch breaking accident.And under the condition of ensuring the melting ditch pattern temperature and preventing the broken ditch accident,the ideal thickness of the ditch wall thickness was 12~16 mm.
