Energy-efficient power supply for induction hardening and heating processes

Induction heating is an established, highly energy-efficient industrial process. The traditional areas of application include, among other things, induction hardening, forge heating, tube welding and annealing as well as the heating and quenching followed by tempering of steel bars or tubes. More and more new applications are being added, as the shortage of fossil fuels means that heating processes are being increasingly switched from oil or gas to electroheat. This does not always mean that conventional furnaces should not be used, rather both combustion furnaces and induction technology can be used intelligently side by side.
