Induction furnace is a furnace that uses current induction to generate heat to heat and melt iron. The structure of the furnace can be divided into two types: Cored type (Figure 2) and coreless type. In coreless induction furnace, the iron in the crucible generates induction current under the action of alternating magnetic field, and thus generates heat, which melts itself and heats the molten iron process. In the cored induction furnace, the molten iron melted by other furnaces (such as cupola) needs to be added, and the alternating magnetic field generated in the ring-shaped iron core makes the molten iron process in the groove, and uses the circulating action of the molten iron in the groove and the molten iron in the upper molten pool to heat all the molten iron. The coreless induction furnace has the ability to melt the solid charge, while the cored induction furnace can only overheat the molten iron, but in the electric energy consumption of the overheated iron, the cored induction furnace is more economical.
