A transverse flux electric induction heating apparatus is provided with a pair of transverse flux inductor assemblies where the inductor in each one of the pair of assemblies is formed from a pair of continuous flexible cables disposed within movable roll channels in roll assemblies that are used to adjust the transverse length of the inductor across the edge-to-edge transverse of a workpiece moving between the inductor in each one of the pair of assemblies and/or to adjust the pole pitch between transverse inductor lengths of each inductor in the pair of assemblies.

Adjustable transverse inductors for inductively heating strips or slabs

A rectangular sheet heating inductor or a multi-turn inductor is provided for induction heat treatment of a strip or slab material that may require a change in the interior opening of the inductor to allow an abnormal region of the material to pass through the interior opening and/or to allow a change in a dimension of the inductor to achieve impedance load matching with a material having variable electromagnetic properties such as a multiphase steel.

Electric induction heating of strip or slab material

An electric induction rail heater is provided for selectively adjusting the heated temperatures in a rail's head, web and foot sections after fabrication of the rail. Alternatively, the rail heater can be used for heating the opposing ends of two rails that are to be welded together. The electric induction rail heater is a transverse flux electric inductor that can be provided with or without magnetic cores.

Electric induction heating of rails

An electric induction gas-sealed tunnel furnace and process are provided. The exterior of the furnace's enclosure that forms a closed tunnel region is surrounded at least along its longitudinal length by a gas-tight barrier chamber that can be filled with a barrier gas to a different pressure than the pressure of the process gas in the closed tunnel region of the furnace. The inductors used to induction heat strips or plates in the closed tunnel region can be positioned within or outside of the gas-tight barrier chamber around the longitudinal length of the closed tunnel region.

Electric induction gas-sealed tunnel furnace

Apparatus and method are provided for electric induction heating and/or stirring of a molten electrically conductive composition in a containment vessel with the apparatus being removably insertable in the molten composition. An induction coil embedded in refractory or a coating is submerged in the composition and used to heat and/or stir the molten composition either externally or internally to the refractory or coating.

Electric induction heating and stirring of an electrically conductive material in a containment vessel

An apparatus and process are provided for controlling the cross sectional temperature profile of a continuously moving workpiece with an induction coil assembly that provides for a combination of longitudinal and transverse magnetic flux field heating of the workpiece. The induction coil assembly includes means for laterally moving the workpiece in and out of the coil assembly without movement of the coil assembly.
