Abstract

A furnace chamber contains a chassis to which a closure plate for said chamber is removably fixed. A tilting frame is borne by said chassis in a pair of coaxial tilting bearings, one of which incorporates a rotary lead through for power lines and cooling lines to an induction coil surrounding a crucible on the tilting frame. The chassis includes a pair of rails which are movable horizontally on wheels mounted to the floor of the furnace chamber.
