Abstract

In the continuous casting process of metals numerous technologies that utilize MHD have been developed in pursuit of higher quality and productivity. One of these, which is still at the trial stage, is the electromagnetic flow rate control. This paper deals with the numerical modeling of the magnetohydrodynamic fields in the travelling electromagnetic valve (EMV), used for liquid metal flow rate control. Optimum values of the supply frequency and of the inductor pole pitch are determined for the imposed flow rate limits and liquid jet characteristics. The two effects of the EMV-flow braking and flow accelerating-are emphasized
