An induction furnace is an electric furnace that processes heat and melts metal through electromagnetic induction. It operates by inducing eddy currents in the metal with a rapidly alternating magnetic field, which heats the metal internally and allows it to efficiently melt.

Key Features:

• Electromagnetic Heating:  An induction furnace will run on direct or alternating current (AC) in a coil, which creates a magnetic field completely independent. This magnetic field induces current in the metal; it generates heat in the metal.
• Clean energy use:  There is no flame or combustion with an induction furnace; this allows for lower pollution, much more consistent results, a high level of control, and a high use of energy efficiency.
• Melting metals: Induction furnaces would typically operate at melting metals like steel, iron, aluminum, copper, and even precious metals in a foundry or recycling plant.

An induction furnace is, by all means, the preferred furnace option today in the metallurgical and manufacturing industries for its heating rates, temperature control, and cleanliness. Induction furnaces are advantageous when being used to produce high-quality alloys with low levels of contamination. The induction furnace would be very much preferred in the steel, jewelry, and aerospace industries to produce alloys where contamination would be very critical. Induction furnaces range from small labs to very large industrial systems. Induction furnaces must have a lining designed to be able to withstand the incredibly high temperatures needed to melt metals, even (again) precious metals and alloys.
