Energy-saving characteristics of steel induction heating furnace

Using induction current to heat steel materials, in contrast to resistance furnace heating and fuel furnace heating, induction heating furnaces have the following characteristics.

The principle of using induction current to directly heat the steel induction heating furnace is based on the electromagnetic induction phenomenon and the heating effect of the current, and relying on the induced current generated inside the steel to quickly heat from the surface to the inside. During the heating process, 86.4% of the current in the permeable layer directly heats the metal, and the remaining 13.6% of the current is in the inner layer of the metal to heat the metal. This direct heating method without heat transfer medium has high thermal efficiency and energy utilization. This type of heating is impossible for traditional heating methods, and is a unique feature of induction heating furnaces.
