Below is a list of Induction Furnaces manufacturers from Roseville, Michigan. Induction furnaces are a type of electrical furnace that uses a combination of electrical resistance and hysteresis losses to heat metal. They tend to be cleaner and more energy-efficient than other types of furnaces. The furnace heats the metal by exposing it to the magnetic field around a coil-carrying alternating current. These enclosed structures use induction heating sources to produce heat for industrial purposes.
