Abstract

PURPOSE: To allow a reflection type melting furnace for nonferrous metal to well show the function by specifying the softening degree of glass with a low m.p. as a coating material coating the surface of molten metal in the furnace to reduce the volatilization and scattering of the coating material and to increase the heat transfer coefft.
CONSTITUTION: In order to prevent the oxidation of molten nonferrous metal in a reflection type melting furnace, the surface of the molten metal is coated with glass with a low m.p. as a coating material. At this time, glass with 700W 1,000 poise viscosity at +50W150°C temp. of the molten metal is used as the coating glass. Since the surface of the molten metal is perfectly coated with the glass coat, the molten metal is not oxidized. The volatilization and scattering of the coating material are reduced, and the heat transfer coefft. is increased to allow the reflection furnace to well show the function.
