To provide a seasoning method for an atmospheric furnace and the atmospheric furnace, in which seasoning can be carried out hardly causing oxidative consumption to an easily oxidizable member.
The atmospheric furnace is provided with an easily oxidizable member such as carbon in the inside, and a heat treatment of the to-be-treated object is conducted in nonoxidative atmosphere. Temperature in the furnace is raised by a heater, while a seasoning gas is being supplied in the furnace. The furnace temperature is maintained at a predetermined temperature T0, at which the oxidative consumption of the easily oxidizable member is suppressed to a small amount. When the dew-point in the furnace is dropped during the maintenance of the furnace-temperature to a predetermined dew-point value D0, at which the oxidative consumption of the easily oxidizable member at a high temperature is suppressed in a small amount, the furnace temperature is raised at least to the predetermined temperature T0, while the in-furnace dew-point is maintained at the predetermined dew point value D0, or lower. The furnace temperature is raised up to furnace-use temperature TB at the operation-start time, and at the same time the in-furnace dew-point is dropped to a use dew-point at the operation-start time.
