Abstract
Melt fed to a continuous casting mold is slowed and spread by a magnetic field acting in the path of the inflowing melt stream. The magnetic field, which is either a static field powered by continuous current, a field powered by permanent magnets, or a field powered by low-frequency alternating current, is applied at at least two spaced-apart locations, either in two separated cast strands or at spaced locations across a wide single strand.
