Abstract
A continuous-casting mold has two relatively long sides and two relatively short sides. Secured to each of the long sides is a box through which coolant is circulated, and in each of these boxes there is provided a plurality of horizontally spaced groups of vertically spaced inductors. Each of these groups is connected to a respective multiphase power supply so that the frequency and/or field strength of the respective magnetic field can be varied from group to group in order to eliminate dead zones within a body of metal being cast within the mold.
