VORRICHTUNG UND VERFAHREN ZUM RÜHREN VON GESCHMOLZENEN METALL MITTELS EINES ELEKTROMAGNETISCHEN FELDES

摘要

Method and apparatus for controlling stirring of molten metal(24) during processing in a metallurgical vessel(20), free of mechanical-contact with the molten metal(24). Efficiencies of metal processing and improvements in metallurgical properties are achieved by selecting configurations and placement of interacting apparatus(40), and by controlling electromagnetic field characteristics. Apparatus(40) can be retrofitted to an existing vessel and a reduction in vessel maintenance results from a decreased rate of slag buildup during usage.
