Atmosphere Furnace

The atmosphere furnace is characterized in that a certain composition of artificial preparation atmosphere is introduced into the furnace at a given temperature to achieve the purpose of heat treatment, such as gas carburizing, carbonitriding and bright quenching, annealing, normalizing, etc. .
The atmosphere furnace mainly has the following characteristics:
In order to control the atmosphere in the furnace and maintain the pressure in the furnace, the working space in the furnace must always be isolated from the outside air, so as to avoid leakage and inhalation of air, so the furnace shell, masonry, furnace door and all external connecting parts such as fans are required. Thermocouples, radiant tubes, push-pull feeders, etc. use 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 automatically controlled. Therefore, various control instruments are required to continuously and periodically measure and adjust the amount of gas supplied to the furnace.
