Abstract: An electric induction furnace for melting and holding a reactive metal or alloy is provided with an upper furnace vessel, an induction coil positioned below the upper furnace vessel, and a melt-containing vessel positioned inside the induction coil with a gap between the outside surface of the melt-containing vessel and the inside surface of the induction coil that can be used to circulate a cooling fluid for cooling the wall of the melt-containing vessel to inhibit leakage of the reactive metal or alloy melt from the vessel. The melt-containing vessel can be integrated with a cooling system for cooling the melt-containing vessel. The melt-containing vessel, induction coil and cooling system can be provided as modular components to facilitate servicing of the melt-containing vessel, the induction coil and the cooling system.

Abstract: A batch charge conveying system is provided for multiple electric induction furnaces where each one of the multiple furnaces has a separate charge conveying apparatus. An assembled batch charge is loaded on a single assembled batch charge transport apparatus that selectively delivers the assembled batch charge to a separate charge conveying apparatus associated with one of the multiple electric induction furnaces.

Abstract: A fluid latent heat absorption electric induction heater is provided for raising the temperature of a fluid supplied to a fluid-driven turbine in a turbine-driven electric power generation system. The fluid latent heat absorption electric induction heater alternatively transfers heat to the fluid by induced susceptor heating, or a combination of inductor Joule heating and induced susceptor heating. The fluid may be water-steam for powering a steam-driven turbine or another fluid used in a phase change system for driving a fluid-driven turbine in a turbine-driven electric power generation system.

Abstract: Large steel ingot casting is accomplished with a top suspended induction heating device supplied with variable power and variable frequency from a power source. By the induction heating and stirring provided by the top suspended induction heating device, metal solidification advances progressively upwards from bottom to top, and the upper molten metal in a riser part compensates for shrinkage of the lower solidified metal in the main part. Inclusions are selectively moved out of the molten metal by a variable electromagnetic stirring force and the formation of casting defects is suppressed.
