Steelmaking in Induction FurnaceIspatGuru
May 24 2018 · Induction furnace is a type of electric melting furnace which uses electric current to melt metal. The principle of induction melting is that a high voltage electrical source from a primary coil induces a low voltage high current in the metal (secondary coil). Induction heating is simply a method of transfer of the heat energy.

Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc and the current in the furnace terminals passes through the charged material.. For steelmaking direct current (DC) arc furnaces are used with a single electrode in the roof and the current return through a conductive bottom lining or conductive pins in the base.
