Abstract

A continuously cast metal strand has its solidified skin supported by a series of closely interspaced pairs of rollers and for stirring at least one magnetic stirrer is positioned outside of some of these rollers with the latter being made of non-magnetic material so they are penetrated by the stirrer's flux to permit magnetic stirring of molten metal within the skin.
