为指导新型电磁感应控制连铸自动浇注系统的应用，需要对感应线圈参数和系统可靠性进行分析。采用实验和数值模拟的方法研究了一个工业钢包（1.5吨）与新系统的浇注时间。计算结果与实验数据吻合较好。研究了大型钢包（300 t）电磁感应系统线圈参数对浇注效率的影响，分析了电磁感应系统对钢包系统温度和等效应力分布的影响。研究结果为大型连铸钢包的卷取工艺提供了最佳的卷取参数。在钢包周围安装保温材料的盘管对钢包的温度分布、热稳定性和结构安全性影响不大。钢包内衬和隔热层符合系统的安全要求。该线圈和钢壳在钢的感应加热过程中，同时浇注可靠。因此，电磁感应控制的自动浇注系统可以安全地应用于钢铁生产。
To guide the application of a new automated steel-teeming system which in continuous casting is controlled by electromagnetic induction technology, the parameters of the induction coil and system reliability need to be analyzed. The teeming time of an industrial ladle (1.5 t) with the new system was investigated using experimental and numerical methods. The calculated results were consistent with experimental data. The dependence of teeming efficiency on coil parameters for a larger ladle (300 t) was investigated; the influence of the electromagnetic induction system on the temperature and equivalent stress distribution in the ladle system was also analyzed. The results provided optimum coil parameters for a larger ladle normally used in continuous casting processing. An installed coil with surrounding insulating material had little influence on temperature distribution, thermal stability, and structural safety of the ladle. The ladle lining and insulation met safety requirements established for the system. The coil and the steel shell performed reliably during induction heating of steel while teeming. Therefore, the electromagnetic induction-controlled automated steel-teeming system can be safely used in steel production.
