Abstract:The electromagnetic field in horizontal electromagnetic continuous casting with alternative electric-ity has been analysed. A mathematical model has been built to describe the field and the electromagnetic levitative force. The result of numerical simulation shows that the levitative force increased parabolically with increase of the electricity current. With increase of the frequency of the electricity, the force increased apparently. However,when the frequency was over a certain value, the increase in the force was not apparent.
Key words: continuous casting electromagnetic field numerical simulation
