  • ELECTRIC INDUCTION HEAT TREATMENT OF AN END OF TUBULAR MATERIAL
    Publication number: 20080099469
    Abstract: A magnetic flux concentrator is used to control the end heating of a tubular material in an electric induction heat treatment process. The magnetic flux concentrator may consist of fixed elements, or a combination of fixed and moveable elements to accommodate end heating of tubular materials having different dimensions or material properties.

  • Multi-Frequency Heat Treatment of a Workpiece by Induction Heating
    Publication number: 20070267407
    Abstract: An apparatus and process are provided for multi-frequency induction heat treatment of workpieces including gears. High frequency power is applied to an induction coil that surrounds the workpiece so that a high frequency magnetic field couples with the workpiece to inductively heat the workpiece. A C-core inductor is coupled to a coil that has low frequency power applied to it. The workpiece is inserted in a gap in the C-core inductor magnetic circuit so that it experiences low frequency Joule effect heating when the low frequency current is applied to the coil coupled with the C-core inductor. Alternatively the workpiece may be inserted around the C-core inductor when the workpiece has an opening.
