为克服传统水口砂对钢水的污染，实现100%自动浇钢，提出了一种利用滑动水口系统电磁感应加热的新方法（电磁浇钢法）。这种新工艺是利用焦耳热来熔化部分或全部新型钢包填充材料（即与钢水成分相似的Fe-C合金颗粒），它是传统水口砂的替代品。采用基于ANSYS电磁和热分析模块集成的数值模拟方法来研究Fe-C合金的外表面温度变化。此外，还研究了线圈结构参数（钢水与线圈之间的距离、线圈的长度和直径）和电流参数（安匝数、频率）对浇注时间的影响。在模拟找到的最佳参数条件下，实现了感应加热顺利浇钢。并通过壳体上的温度场分布检验了最优参数电磁感应加热作用下钢壳体的安全性。
A new method (electromagnetic steel-teeming method) using electromagnetic induction heating in slide gate system was proposed to overcome the pollution of traditional nozzle sand on the molten steel and achieve 100% automatic steel teeming. By Joule heat, this new process is to melt part or the whole of a new ladle well-packing materials (i.e. Fe–C alloy particles with similar composition as the molten steel), which is the substitute for traditional nozzle sand. A numerical simulation method based on the integration of both electromagnetic and thermal analysis modules of ANSYS was employed to investigate the outside surface temperature change of the Fe–C alloy. In addition, the effects of the coil structural parameters (the distance between the molten steel and the coil, the length and the diameter of the coil) and electric current parameters (ampere-turns, frequency) on teeming time were investigated. Under the condition of the optimal parameters found according to simulation, the smoothly steel-teeming using induction heating was achieved. The safety of the steel shell under the action of electromagnetic induction heating with the optimal parameters was also checked via the distribution of temperature field on the shell.
