Abstract
The present invention relates to a process for the electromagnetic casting of metals. The process is characterized by simultaneously using a stationary field and a variable field at a suitable frequency for producing both radial vibrations within the metal which is not yet in a solidified condition and limiting agitation of the metal. The invention can be used in any circumstance where both the structure and the surface condition of the cast products are to be improved.
