Vacuum atmosphere furnace

Release time: July 6, 2018 15:23:26 Views: 205

        Vacuum atmosphere furnace A negative pressure vacuum environment is formed inside the closed furnace body, and the heat medium water is filled in the body. The heat medium water is heated by combustion or other methods, and then evaporated and condensed to the heat exchanger, and then the water to be heated is heated by the heat exchanger.

Vacuum atmosphere furnace is used for heating in vacuum environment. It is mainly used for ceramic firing, vacuum refining, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic metal sealing.

The furnace body of vacuum atmosphere furnace is divided into upper and lower parts; the upper part is a vacuum chamber (negative pressure steam chamber), in which a tubular steam water heat exchanger is installed to heat the circulating water flowing through the heat exchanger. Operation principle: when the vacuum hot water boiler is running, the heat medium water in the furnace absorbs the heat energy released by fuel combustion under vacuum negative pressure, boils and vaporizes into low-temperature steam. When the low-temperature steam rises, it meets the system circulating water in the stainless steel heat exchanger, and the heating circulating water is sent to the user for heating or sanitary hot water. The water vapor itself is cooled and condensed into water drops, falling to the water surface of the heat medium, and then heated again, thus completing the whole cycle process.

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.
