介绍了一种基于有限元模型的电磁旋转搅拌器的数值模型。这种搅拌器被用来提高连铸钢的质量，特别是小方坯和方坯。该方法确定了磁通密度分布，并与实验测量结果进行了比较。此外，它还计算作为搅拌器位置、施加的电流和频率的函数的洛伦兹力场。模具末端的搅拌器位置会影响力的轮廓对称性，从而创建力的z分量。利用该模型，可以模拟钢液中的流体动力学效应。
This paper introduces a numerical model of an electromagnetic rotary stirrer based on the finite-element model. Such stirrers are used to improve the quality of continuously cast steel, particularly billets and blooms. The method determines the magnetic flux density profile and compares it to experimental measurements. In addition, it calculates the Lorentz force field as a function of the stirrer position, the current applied, and the frequency. The stirrer position at the end of the mold affects the profile symmetry of the force, creating a z component of the force. With this model, it will be possible to simulate the fluid dynamics effects in the molten steel.
