What Is an Induction Furnace?
An induction furnace is a type of furnace that uses electromagnetic induction to heat materials. Induction furnaces are used in a variety of industries, including the steel, aluminum, copper, and glass industries. The major components of induction furnaces include sensor(s), furnace(s), power supply, capacitor(s) & control system(s). When the action of alternating electromagnetic fields happens in induction furnaces, eddy currents get generated in the material(s) for achieving a heating effect/melting effect. In the stirring effect of alternating magnetic field(s), material composition as well as material temperature in the furnaces become uniform (relatively), and forging heat-temperature(s) can even reach up to 1250°C, and the melting point(s) can even reach up to 1650°C. Besides being heated/smelted in the atmosphere, induction furnaces can even be heated/smelted in a vacuum, and can even be heated/smelted inside a protective atmosphere like argon/helium for meeting specific quality requirement(s).
Types of Induction Furnaces
Induction furnaces are broadly divided into 2 main types, as given below:
- Heating Induction Furnaces: These electric furnaces heat material with the help of an induced current that gets generated through the induction-coil. If the material (metal) gets heated, then it’s placed inside a crucible, which is made from the refractory material. If the material (non-metal) is heated, then it’s placed inside a graphite crucible. When AC frequency increases, the frequency of that induced current gets augmented accordingly, and the heat that is being generated is also amplified.
- Melting Induction Furnaces: Melting induction furnaces are divided into 2 major types, as follows:
- Core Induction Furnaces: These have a core passing through the inductor, powered by the commercial-frequency power-supply. These are largely utilized for the purposes of melting as well as for heat preservation of various metals including bronze, cast iron, zinc, brass, etc.
- Coreless Induction Furnaces: These have no iron core to pass through the inductor, and these are further divided into the following types:
- High-frequency induction furnaces
- Triple-frequency induction furnaces
- Power-frequency induction furnaces
- Thyristor intermediate-frequency induction furnaces
- Generator-set intermediate-frequency induction furnaces
