The induction heating furnace can implement rapid heating with high energy flow density
The induction heating furnace can implement rapid heating with high energy flow density. The energy flow density refers to the energy value applied to the unit surface area of the heated steel. The amount of energy applied is proportional to the heating rate of the steel. Under the conditions of induction heating furnace, the energy flow density is the surface power density. When the steel is heated, the greater the surface power density, the faster the temperature of the steel is, the heating time is shortened correspondingly, the heat loss is correspondingly reduced, and the heat energy utilization rate is improved. At present, the electric heating method used in industrial production can achieve the energy flow density. In terms of electric heating and heat treatment of steel, the induction heating furnace is the heating method with the highest energy flow density. Electron beam and laser beam heating are limited to heat treatment of special parts. High energy flow density and rapid heating are important energy-saving approaches for rapid heat treatment of steel induction heating furnaces.
