Abstract
The present invention concerns an induction furnace. It is the object of the invention to increase the power of such furnaces while maintaining their weight or space requirements, or, to reduce their weight or space requirements for a given power, or further to design machines more powerful than those known at the present time. There exist at this time crucible induction furnaces designed for a capacity of approximately 30 t of cast iron. The invention permits the adaptation of such a furnace to melt not case iron, but steel and to increase the capacity of said furnace to a higher order of magnitude, for example 100 t or more. To enable the furnace to satisfy the requirements of steel making, the invention also provides for an increase in specific power, presently limited to approximately 300 kW/t.
