Abstract
Apparatus and methods for stirring a molten metal are provided. The apparatus comprising: two or more discrete units, each unit including a core being provided with two or more teeth, the core being provided with at least one electrically conducting coils; in use, mounting a first discrete unit in proximity to the container at a first location; in use, mounting a second discrete unit in proximity to the container at a second location; electrical connections between the two or more discrete units and a common control unit, thereby providing an electromagnetic stirrer. The apparatus format allows the discrete units to be position between different pairs of elements or parts of furnaces and the like to allow retrofitting of electromagnetic stirring where access is restricted.
