The first induction furnace for three –phase application was built in Germany in 1906 by Rochling-Rodenhauser. Original designs were for single phase and even two phases were used on the three phase furnace. The two basic designs of induction furnaces the core type or channel furnace and the coreless are certainly not new to the industry.
