Abstract

PURPOSE:To execute the continuous heat treatment for the rod at good efficiency independently of the rod diameter, by installing the sealing device utilizing the magnetic fluid in the sealing atnd, and the sealing device as the rod cooler in the cooling stand. CONSTITUTION:When the rod 1 is pushed its way through the magnetic fluid layer 16 being formed inside of the magnetic poles 7, 9, installed in the sealing stand 3, the magnetic fluid layer 16 is adsorbed by the inner face of magnetic poles 7, 9, and the outer face of the rod 1 facing to the poles 7, 9, because of generation of the magnetic field. Therefore, even if the rod 1 is moved forward, the nonoxidizing atomosphere is maintained in the external air excluding heat-resisting tube 13. After being heated to the specified temperature while passing through the induction heating coil 2, the rod 1 is cooled by the liquid jet spouted from the coolant injection hole 24 of the cooling stand 4, and the heat treatment is completed. By this injected coolant film, inside of the external air excluding heat resisting tube 13 is maintained at the nonoxidizing atmosphere. After the rod 1 passed through the apparatus, the magnetic fluid film is restored over whole inner face of the hollow passage.
