1. A method of induction heat treatment for a circular workpiece, the method comprising the steps of:
- placing the circular workpiece on a horizontal and lateral support structure disposed within an induction coil with a side wall of the circular workpiece vertically oriented to transport the circular workpiece from a coil entry position to a coil exit position; and
contacting the side wall of the circular workpiece with a workpiece pusher element that is not directed through the central axis of the circular workpiece the workpiece pusher element connected to a drive apparatus for moving the workpiece pusher element through the induction coil so that contacting the side wall of the circular workpiece with the workpiece pusher element simultaneously rotates the circular workpiece in the horizontal and lateral support structure and advances the circular workpiece through the induction coil.

Abstract
A cylindrical workpiece is mounted between opposing friction and non-friction guide rails and pushed through an induction coil arrangement by a pusher element positioned relative to the workpiece so that the pusher element introduces a force that moves the workpiece linearly forward within the induction coil arrangement between the two guide rails and rotationally by kinetic friction of the workpiece with the friction rail.

5. An induction heat treatment apparatus for a circular workpiece, the induction heat treatment apparatus comprising:
-
an induction coil; a horizontal and lateral support structure disposed within the induction coil for transporting the circular workpiece disposed on the horizontal and lateral support structure through the induction coil; a workpiece pusher element; and a drive apparatus connected to the workpiece pusher element and oriented so that the workpiece pusher element engages a side wall of the circular workpiece and applies a force that is not directed through the central axis of the circular workpiece to simultaneously rotate the circular workpiece in the horizontal and lateral support structure and advance the circular workpiece through the induction coil when the drive apparatus is activated. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of induction heat treatment for a workpiece having at least one circular component, the method comprising the steps of:
-
placing the at least one circular component on a horizontal and lateral support structure disposed within an induction coil with a side wall of the circular component vertically oriented to transport the circular component from a coil entry position to a coil exit position; and contacting the side wall of the circular component with a workpiece pusher element that is not directed through the central axis of the circular component the workpiece pusher element connected to a drive apparatus for moving the workpiece pusher element through the induction coil so that contacting the side wall of the circular component with the workpiece pusher element simultaneously rotates the circular workpiece in the horizontal and lateral support structure and advances the circular workpiece through the induction coil.
