摘要： A device to generate and direct electric heat 10 for use over risers, drains, pathways and pour cups during solidification in which less than 2% plasma is utilized, comprising an outer shell 20 having one open heat delivery end 25, at least one lip 30 located at the open end 25, one closed end 35, at least one electric heating element 80 affixed within the closed 35 end and refractory material 60 surrounding the electric heating element 80. A method, employing said device 10, 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, said atmosphere of less than 2% plasma thereby controlling temperature during the solidification and shielding the molten cast surface from the affects of oxidation.
