characteristic:

The characteristic of atmosphere furnace is that at a given temperature, artificial atmosphere with certain composition is introduced into the furnace to achieve some purpose of heat treatment, such as gas carburizing, carbonitriding and bright quenching, annealing, normalizing, etc. The atmosphere furnace has the following characteristics:

Tightness:

In order to control the atmosphere in the furnace and maintain the pressure in the furnace, the working space in the furnace should always be isolated from the outside air to avoid air leakage and air inhalation. Therefore, the furnace shell, masonry, furnace door and all external connecting parts such as fans, thermocouples, radiant tubes, pushers and pullers are required to adopt sealing devices;

Atmosphere control:

In order to maintain a certain carbon potential in the furnace, in addition to controlling the stability of the atmosphere composition, it is necessary to

The atmosphere is controlled automatically. Therefore, it is necessary to set up various control instruments to continuously or regularly measure and adjust the gas supply in the furnace.
