Abstract

PURPOSE: To eliminate defective parts and reduce the cost with simple construction by providing a heating mechanism and an eliminating mechanism for the defective parts of joining parts.
CONSTITUTION: A heating coil 2 and fluid ejecting nozzles 3 as an eliminating mechanism are mounted to a carriage 5 which is built in with a power unit and the like, and the carriage 5 is placed on rails 7 disposed in parallel with the moving direction A of a billet 1. The coil 2 is formed in a manner as to encircle the circumference of the billet 1, and the nozzles 3 are disposed near the coil 2. High frequencies corresponding to the thicknesses of defective parts are applied to this coil, to locally heat and melt only the surface layer of the red hot billet 1. Defective parts 4 are blown off by ejecting pressurized fluid from the nozzles 3 provided respectively on the four vertical and lateral sides of the billet 1.
