Electromagnetic Brake (EMBR) for slab caster in steel making

Description

EMBR, which stands for Electromagnetic Brake, is a kind of electromagnetic metallurgical equipment for CCM, usually installed at the back of copper plate/water tank of mold. The main function of EMBR is to generate a constant static magnetic field across the molten steel on the two wide faces of the slab mold, the direction of it is perpendicular from one wide face through the molten steel to the other one. The flow strand from the SEN with a considerable speed to cut the generated constant magnetic field vertically, producing an induced current in the molten steel, which interact with the constant static magnetic field to generate electromagnetic force.

Application

Electromagnetic brake(EMBR) of mold for slab is a necessary equipment for high-speed continuous casting of

conventional thick slab, continuous casting and rolling of thin slab (CSP) and endless rolling (ESP)production.

Functions

A pair of EMBR with width equivalent to that of mold installed on two wide faces of the slab mold can generate a magnetic field that vertically penetrate the mold. And the flow velocity of molten steel flow from two orifices of SEN be reduced under the effect of magnetic field so as to improve the flow field, reduce the impact of the molten steel, and finally obtain improved surface and internal quality of the strand.
