Electromagnetic Flow Control in Metals Processing Operations

A review is given of the current metals processing operations, where electromagnetic forces play an important part in affecting the performance of the system. These include arc furnaces, plasmas, the Hall Cell, electromagnetic stirring and others. These considerations will be extended to discuss what new frontiers may be breached by the intelligent application of electromagnetic phenomena. The topics discussed will include magnetic flow control, levitation melting and cold crucible melting and refining.
