Method and apparatus for inductively heat treating elongated workpieces
Abstract
Abstract A METHOD AND APPARATUS FOR INDUCTIVELY HEATING AND QUENCHING ELONGATED WORKPIECES WHEREIN THE WORKPIECES ARE LONGITUDINALLY CONVEYED ALONG A WORKPIECE PASS. THE INDUCTION HEATING INDUCTOR IS POSITIONED WITHIN AN ELONGATED GENERALLY CYLINDRICAL TRANSFORMER SECONDARY WINDING WHICH IS POSITIONED TO SURROUND THE WORKPIECE PASS. DURING ENERGIZATION OF THE TRANSFORMER FOR RESULTANT ENERGIZATION OF THE INDUCTOR AT LEAST THE TRANSFORMER SECONDARY WINDING AND INDUCTOR ARE CONTINUOUSLY ROTATED ABOUT THEIR LONGITUDINAL AXES, WHILE THE WORKPIECES ARE CONVEYED ALONG THE WORKPIECE PASS, TO ASSURE EVEN HEATING OF THE WORKPIECES. MEANS ARE PROVIDED ADJACENT THE TRANSFORMER SECONDARY WINDING FOR COOLING THE SECONDARY AND ADJACENT THE INDUCTOR FOR QUENCHING THE WORKPIECE IMMEDIATELY FOLLOWING HEATING.
