come in 2 quite different versions. In version A, a “lower furnace with an integrated low induction coil” is flange-fitted below a “cylindrical upper furnace” without cooling equipment. The iron piles are fitted only in the area of the furnace coil. Version B consists of a crucible furnace with a low induction coil and a cooling coil made of V2A material installed directly in the coil extension. The iron piles are fitted with electro-plate in the area of the coil, and in the area of the cooling coil, only the extended side plates with their welded bridges serve to support the cooling coil against the furnace body. Die losses with Type B are approx. 15% lower than with Type A, due to the higher induction coil.
