NONFERROUS METAL MELTING FURNACE, NONFERROUS METAL MELTING METHOD AND NONFERROUS METAL MELTING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a nonferrous metal melting furnace, a nonferrous metal melting method and nonferrous metal melting equipment which can be configured as a small size capable of installation adjacent to a casting machine, produces high-quality nonferrous metal molten metal and has high heating efficiency.SOLUTION: A nonferrous metal melting furnace 1 includes: a melting container 10 which retains aluminum molten metal (nonferrous metal molten metal) Y of induction magnetic field efficient temperature as a temperature bringing about a volume resistivity capable of direct heating by using an inductive magnetic field or more and allows an aluminum ingot G as aluminum melting raw material (nonferrous metal melting raw material) to be charged thereto; and an inductive heating coil 60 which directly heats the aluminum molten metal of the inductive magnetic field efficient temperature or more in the melting container and the aluminum ingot of the inductive magnetic field efficient temperature or more by using the inductive magnetic field without directly heating the melting container.SELECTED DRAWING: Figure 4
