摘要： Provided is a method of annealing a metal member, including: disposing a first heater in an inner space of a hollow cylindrical metal member having an inner peripheral surface provided with plural teeth protruding toward a central direction, the first heater radiating infrared light and being disposed so as to extend parallel to a direction of a central axis of the metal member; heating the metal member from the inner space with the first heater; and gradually cooling the metal member after heating.

摘要： A continuous annealing facility comprised of a heating zone, soaking zone, and cooling zone is used for continuous annealing of a steel strip having a Curie point (Tc) by an annealing temperature over Tc during which the heat treatment in the heating zone is divided into three regions, in a first heating zone, a radiant heating means using gas heating and/or a radiant heating means using electric heaters is used to heat the steel strip to less than Tc-50°C, in a next second heating zone, the heated steel strip is heated by a solenoid coil type high frequency induction heating means to a region of Tc-30°C to Tc-5°C, and, in a final third heating zone, the heated steel strip is heated by a radiant heating means using gas heating and/or a radiant heating means using electric heaters to a treatment target temperature over Tc to thereby anneal a steel strip having a Curie point uniformly in the longitudinal direction.
