What is induction heating?
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.
