Induction heating models are more an exotic variation. The amount of carbon in the system is reduced in case of induction heating, but specific graphite parts are still required, like the susceptor or the insulation material. In any case, induction heating bears a certain risk of water spilling since the copper tubes have to be water-cooled.

Oxidizing conditions were intensified by using oxygen and additional air. A charge of pig iron containing, in percent, Fe 89.3, Si 5.1, C 3.8, P 0.19, and S 0.01 was melted in a zirconium silicate crucible by induction heating. Limestone, to the extent of 20 percent of the charge weight, was placed on the molten metal at 1,350 C.

Nov 07, 2019 An induction furnace works by transferring heat energy via a high-voltage primary coil that induces a high current, a low voltage, or a secondary coil. These types of furnaces are great for melting a wide array of metals while maintaining a low level of melt loss. There are two main varieties of these furnaces coreless and channel.
