摘要
PURPOSE:To enable a heat treatment in a rotating magnetic field effective in a wide furnace core by providing two magnetic poles consisting of a permanent magnet to the inside wall of a cylindrical yoke enclosing the furnace core and rotating the magnetic poles together with the yoke. CONSTITUTION:The permanent magnet 2 is provided to the inside wall of the cylindrical yoke 1 consisting of a mild steel and the yoke 1 is rotated by means of a motor 10 via a belt 3 and ball bearings 4. Since the sufficient external magnetic field is thereby used, the heat treatment in the rotating magnetic field effective throughout the wide furnace core 5 including jigs, etc., is executed.
