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.

Induction furnace for melting and casting substances in a nonreactive

A mold table is linearly moved into a pouring position or a resting position in a vacuum casting unit and rotates around its vertical axis so that the ingot molds disposed on the mold table can be individually positioned in front of the pouring nose of a crucible. A flexible belt-type roller device, for example a roller chain 15 as used in the chain drive of a crawler, is guided around a rod-like carrier 13 disposed in direction F in the mold chamber, and a catch 16 is integrated into this flexible, belt-type device. A separate drive, preferably a rope drive, is provided for moving the apparatus 10, this drive being connected to the rotatable catch 16 generating the rotation of the mold table. All motors for linearly moving and rotating the mold table are disposed outside the vacuum chamber.
