Vacuum Induction Melting Furnaces
VIM — The Process
Vacuum Induction Melting (VIM) is the melting of metal via electromagnetic induction under vacuum. An induction furnace containing a refractory lined crucible surrounded by an induction coil is located inside a vacuum chamber. The induction furnace is connected to an AC power source at a frequency precisely correlating to the furnace size and material being melted.
