ABSTRACT:
A housing including an open-cage type framework for a coreless induction furnace. The framework includes upper and lower horizontally disposed ring members. Each ring member is constructed of a non-magnetic metal except for an insulating fastener in each ring which closes the ring mechanically but prevents a continuous electrical path or loop in each ring. The upper and lower rings are joined by a plurality of vertical columns which are similarly electrically insulated from the rings. The framework thus provides a rigid structure for supporting the internal furnace components while at the same time insuring that deleterious current paths or loops in the framework are not created during operation.
