摘要

以自行研制的旋转永磁体电磁铸机磁感应器为对象，建立了计算旋转永磁体磁场的数学模型，数值模拟分析了磁极直列排布方式（六极三对、八极二对、八极四对、十二极三对、十二极六对）下的磁场分布特点及规律，进一步探讨了磁极螺旋式排布的磁场特征，指出应充分利用临界点以外边缘区的强磁场，并采用螺旋式多磁极数配置，以利于强化电磁搅拌的效果。

Abstract

The mathematical model for simulating the magnetic field generated by rotating permanent magnets in the electromagnetic caster is built

and the distribution of magnetic field generated by straight induction stirrer（six poles three couples

eight poles two couples

eight poles four couples

twelve poles three couples

twelve poles six copules） is simulated and analyzed. Furthermore

the character of magnetic field generated by helical induction stirrer is discussed. Meanwhile

thoroughly taking advantage of the verge of powerful magnetic field beyond the critical pint generated by helical induction stirrer with more magnetic poles are put forward to reinforce the effect of stirring.
