摘要：

A three-dimension mathematical model of steel solidification and electromagnetic brake(EMBR) in the billet mold is presented according to the basic theory of magnetohydrodynamics and Bennon's continuous media model. By numerical simulation of electromagnetic field, fluid flow and heat transfer, it was shown that the electromagnetic force opposite to the fluid flow is the direct cause of EMBR. The induction current mainly concentrates in the region near entrance. The electromagnetic force can alter effectively the distribution of flow field and temperature field, which results in a plug-like flow in the EMBR region, decreases the temperature gradient in the high temperature region, raises the temperature near meniscus, especially in the up corner region and decreases the solidification thickness there.
