In induction melting, material is melted, alloyed and kept warm in a furnace. In addition to the inductive power input, the stirring effect created by the inductive force on the melt is used on purpose to distribute the heat and stir the alloying elements.
Essentially, there are two different designs. The crucible furnace has a cylindrical coil and very high installed capacity. It is mainly used for melting. There is also the channel furnace, which consists of looped channels surrounding a core of magnetic sheets and in which power is induced in the channel by a transformer-type coil. It is flanged at the bottom or side to a large crucible and is mainly used for keeping material warm.
