Abstract

The three-dimensional, time-dependent electromagnetic field arising from the precession of the arc centre in a vacuum arc remelting furnace is shown (in a numerical simulation) to affect the fluid flow and heat transfer conditions near the solidification front in the upper part of the ingot.
