METHOD AND APPARATUS FOR INDUCTION-HEATING OF BILLET

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for induction-heating with which in the method and the apparatus for induction-heating of a billet for forging by heating a columnar billet 13, especially the columnar billet 13 having large weight and diameter, a scratch generated in a billet conveying way in the induction-heating apparatus 1 is restrained and diffusion-joining of both billets 13 is restrained.;SOLUTION: In the inner part of the billet heater 18 including an induction-heating coil 24, an upgrade conveying way is disposed and the columnar billet to be heated (for example, the columnar billet 13) is supplied as sideways to the billet-heater 18 and the billet 13 is made to move forward towards an outlet from an inlet, while automatically rotating the billet 13 by an aligned state sideways, and heated.;COPYRIGHT: (C)2010,JPO&INPIT
