Abstract
An electromagnetic flow control valve for an electrically conductive liquid having a plurality of coils and yokes surrounding a non-metallic, such as alumina, tube through which an electrically conducting liquid, such as liquid metal, flows. Direct current applied to the coils causes retarding forces to be imposed on the flowing liquid. The electromagnetic flow control valve can be used in conjunction with a continuous caster where the electromagnetic flow control valve is in fluid communication with a tundish. Built-in galvanomagnetic probes measure changes in the applied magnetic field to determine the rate of flow of liquid metal through the device.
