A device for inductively heating the edges of elongated movable workpieces, includes an inductor having vertical pole surfaces disposed one above. The edge of the elongated movable workpiece is maintained at a given distance from and completely outside the inductor, so that the workpiece cna move up and down completely freely relative to the inductor.

Industrial oven providing air recirculation for heat treatment processes having temperature uniformity within a charge to be treated, including oven walls, spacers disposed between the oven walls for supporting the charge at a distance from the oven walls defining a space therebetween and for allowing a recirculated hot air flow around the charge from all sides, and elements disposed in the space between the charge and the oven walls for influencing the air flow.

Industrial oven with air recirculation for heat treating processes

Induction crucible furnace for maintaining or increasing the temperature level of a metal melt, characterized by the feature that the inlet of the melt to the crucible furnace is arranged below the bath level in the furnace.

Continuous-flow heater for molten metals

A controlled atmosphere furnace having radiant heating tubes, through which hot gases from a fuel burner are passed, is converted to electrical operation by removing the fuel burner and exhaust connections from the heating tubes and replacing these with electrical connector extensions connected to an electrical power source so that electrical current is driven longitudinally through the heating tube walls and converted therein to heat which is radiated into the furnace enclosure.

Furnace conversion method and apparatus

An induction crucible furnace having a crucible surrounded by an induction coil member that is prestressed in axial direction by ring members disposed at opposite ends of the coil member and connected together by a plurality of tie rods extending parallel to the axis of the coil member and distributed uniformly about the periphery of the crucible one of the ring members being fixed to a base frame of the furnace, includes spacer means disposed between the ring members and the coil member and having inner and outer diameters matching those of at least one of the members.
