Zusammenfassung:	RD-19-666 PROCESS FOR PREVENTING CONTAMINATION OF HIGH TEMPERATURE MELTS A method of reducing "fall back" contamination caused by high intensity heating of metals is taught. Splatter, vapor droplets and particulate matter resulting from the high intensity heating is repelled to avoid return to the melt. An electric field is established above the heating zone to repel the vapor droplets and particles foam at least one charged electrode disposed above the surface where high intensity heat is applied to a metal surface.
