摘要： An apparatus and process are provided for controlling the heating or melting of an electrically conductive material. Power is selectively directed between coil sections surrounding different zones of the material by changing the output frequency of the power supply to the coil sections. Coil sections comprise at least one active coil section, which is connected to the output of the power supply, and at least one passive coil section, which is not connected to the power supply, but is connected in parallel with a tuning capacitor so that the at least one passive coil section operates at a resonant frequency and the output frequency of the power supply is changed so that the induced power in the at least one passive coil section changes as the frequency is changed.

摘要： An apparatus and process are provided for inductively heating a workpiece to a desired cross sectional temperature. At least one pair of coils form a transverse flux inductor. The workpiece is located between the pair of opposing coils, which are oriented across the cross section of the workpiece. Each coil comprises a plurality of coil sections. The distance between one or more opposing coil sections is adapted to achieve the desired cross sectional induction heating temperature profile in the workpiece. Alternatively the distance between all opposing coil sections are equidistant from each other, and one or more flux concentrators, moveable at least in a direction perpendicular to the surface of the workpiece, can be used to achieve the desired cross sectional induction heating temperature profile in the workpiece.
