Abstract

The present invention is provided with: an in-furnace atmosphere gas concentration sensing device which senses the hydrogen concentration or the ammonia concentration in a treatment furnace; an in-furnace nitriding potential calculation device which calculates the nitriding potential within the treatment furnace on the basis of the hydrogen concentration or the ammonia concentration sensed by the in-furnace atmosphere gas concentration sensing device; and a gas introduction amount control device which changes the introduction amounts of a plurality of gases, excluding an ammonia decomposition gas, to be introduced into the furnace in accordance with the calculated nitriding potential within the treatment furnace and a desired nitriding potential, while maintaining the introduction amount of the ammonia decomposition gas constant, thereby bringing the nitriding potential within the treatment furnace closer to the desired nitriding potential.
