What is an induction furnace?
Just like all other furnaces, an induction furnace is used to heat the materialS (usually metals) to their melting point so that they melt for further processing. The difference is that an induction heater relies on induction heating to get the job done.
An induction furnace is different from other sorts of furnaces because it is usually used for stirring the melted metal so that the alloying additions are adequately mixed into the resulting metal while it’s hot. Induction furnaces are used in most modern applications as a cleaner of metals rather than one that actually makes them or preparing them for shaping or forming.
Induction furnaces are non-contact furnaces that ensure the cleanness in the process to enable usage in inert atmosphere or vacuum, such as for production of specialty alloys and steels that would be easily oxidized in heating by air.
