Abstract
A rotary heating apparatus to heat evenly symmetrical and/or non-symmetrical workpieces. A rotatable shaft holds directly or indirectly one or more workpieces. The shaft has a first major central elongated axis. An induction coil providing a magnetic field and has a second major central elongated axis. The coil is fabricated with an open space in a side of the coil. The open space is configured and dimensioned to accommodate the passage of the shaft while avoiding contact between the shaft and any portion of the coil. The shaft is arranged so that said first major axis is positioned perpendicular to the second major central elongated axis. The shaft rotates workpieces within the coil in a plane which includes the second axis or in a plane which is parallel to the axis so that the rotating workpiece crosses through multiple lines of flux of the magnetic field to ensure even exposure of the workpiece to the magnetic field provided by the coil for consistent uniform heating of the workpiece regardless of different thicknesses of the workpiece.
