Abstract
A mathematical representation has been developed to describe the three-dimensional velocity and temperature fields in shallow tundishes to be used in novel continuous casting systems. Particular attention has been paid to the effect of externally imposed magnetic fields in modifying the flow. It was found that the imposition of vertical or horizontal fields may play an important role in minimizing flow non-uniformities and hence variations in the temperature of the stream entering the mold of the caster. In the absence of (magnetic) flow control arrangements, serious flow and temperature maldistribution may occur, especially in the production of wide strip or thin slabs. The effect of magnetic fields on inclusion removal has also been investigated, but the inclusion removal efficiency of shallow tundishes is thought to be low in any case.
