Abstract
A method is provided for suppressing a vortex arising in a tundish or ladle at the lowering of the free surface of the melt below a critical level using a rotating magnetic field excited in the melt above an outflow pipe by an RMF inductor of a special design.
Claims11
A method of suppressing a vortex arising in a tundish or ladle at the lowering of the free surface of a melt below a critical level using a rotating magnetic field (RMF) continuously excited by 5 m-phase current in the melt above an outflow pipe, wherein the direction of RMF rotation is opposite to the direction of melt rotation in the vortex.
