用场、路结合法分析感应钢包炉的等效电路

Combination of Field and Current for Analysis of Induction Ladle Furnace's Equavalent Circuit

本文首先提出感应钢包炉的等效电路，而后从感应钢包炉的空载、负载和漏磁场的边值问题出发，利用有限元法，计算了这三种场，由此分析了等效电路中的各参数及性能的计算方法；其中在计算包壳中的涡流损耗时，利用了对偶有限元法．

In this paper, equivalent circuit of induction ladle furnace is presented. By the computaion of induction ladle furnace's unload, load and leakage magnetic field, the solutions of parameters in the equavalent circuit and the property of the furnace are obtained. And conjugate finite element method is used for the computation of ohmic losses in the shell.
