Georg Fischer (GF) has recently commissioned a new production line for light-weight iron castings at its Mettmann, Germany, location. Like in the existing manufacturing lines, the liquid iron is supplied by a hot blast cupola via downstream channel induction furnaces. To cover the extra peak demand and for risk considerations, it has become necessary to install a fourth channel induction furnace, which like the other three storage furnaces receives the metal from the cupola directly via open launders. Experience from the existing metal storage equipment gained by both the furnace operator and the furnace builder, ABP Induction Systems GmbH based in Dortmund, Germany, has been taken advantage of in the design and installation of the final arrangement of four channel induction furnaces. This applies not only to the furnace and inductor technology but also to the innovative water-hydraulics systems and the control system that monitors furnace and inductor operation.
