【摘要】 通过用ANSYS软件对脉冲电流作用下钢液中电磁场分布的数值模拟,得到了钢液中电流密度、磁感应强度、电磁力的分布情况,计算了不同峰值脉冲电流产生的电磁力,分析认为,电磁力碎断枝晶不是脉冲电流细化钢凝固组织的主要原因。更多还原

【Abstract】 In this paper, with the FEM analysis software-ANSYS, the electromagnetic field in molten steel while applying pulsed current was simulated, and the distribution of current density, magnetic flux density and electromagnetic force in molten steel were studied. The deferent electromagnetic force under deferent pulsed current was computed, the results show that breaking dendritic by electromagnetic force is not the main reason for pulsed current in improving steel solidification structure.更多还原
