分析了二相系统和电磁感应器的结构 ,描述了系统中高次谐波电流和正、反旋转感应电动势对晶粒细化效果的影响 ,得出了在铝溶体中通入直流电可以改善系统的电磁转矩和机械特性的结论
The structure of the two-phase system and the electromagnetic sensor are analyzed. The influence of high-order harmonic currents and positive and negative rotation induced electromotive forces on the grain refining effect is described. It is concluded that direct current can be improved by introducing the direct current into the aluminum melt Torque and mechanical characteristics of the conclusion
