What is induction heating?

Answer 1

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal.induction heater including high frequency induction heating machine and middle frequencey heating machine.

Induction heating applications for an induction furnace include induction welding, induction brazing, induction hardening, induction melting, quenching, forging, soldening, induction annealing and other forms of heat treatment.

Induction heating is often used to heat graphite crucibles (containing other materials) and is used extensively in the semiconductor industry for the heating of silicon and other semiconductors.

Induction heating can produce high power densities which allow short interaction times to reach the required temperature. That translates into lots of energy transferred into a material right now, with a very rapid rise in temperature.

Answer 2

Heat induction is when an electrically conducted object is heated by electromagnetic induction. Some furnaces have this type of process.
