Abstract
A device to generate and direct electric heatfor use over risers, drains, pathways and pour cups during solidification in which less than 2% plasma is utilized, comprising an outer shellhaving one open heat delivery end, at least one liplocated at the open end, one closed end, at least one electric heating elementaffixed within the closedend and refractory materialsurrounding the electric heating element. A method, employing the device, to improve the properties of cast alloys which comprises the heating and blanketing of a molten cast surface with an atmosphere of less than 2% plasma during solidification, the atmosphere of less than 2% plasma thereby controlling temperature during the solidification and shielding the molten cast surface from the affects of oxidation.
