Protech atmosphere furnace manufacturers to share with you: the atmosphere furnace is characterized at a given temperature, the furnace with the preparation of certain components of artificial atmosphere, in order to achieve some kind of heat treatment purposes, such as gas carburizing, carbonitriding and Bright hardening, annealing, normalizing. Atmosphere furnace has the following characteristics:
1. furnace tightness In order to control the atmosphere in the furnace, to maintain pressure in the furnace, the furnace working space should always be isolated from the outside air, try to avoid leaks and the intake air, and called for the furnace shell, masonry, door and all external connections parts such as fans, thermocouple, radiant tube, feeding machines using sliding sealing device;
2. The furnace atmosphere control In order to maintain a certain furnace carbon potential, in addition to controlling the atmosphere composition stability, but also to automatically control the furnace atmosphere. Therefore, with a variety of control instruments, in order to the furnace atmosphere continuously or periodically measuring and adjusting the amount of gas in the furnace.
3. The heating method In order to ensure the stability of the atmosphere, the atmosphere muffle furnace can be divided into two muffle furnace and no, muffle furnace flames in a muffle outside, the workpiece is heated in a muffle indirect; no muffle furnace using a variety of flame radiant tubes or electric radiant tube, separating the flame or electric heating element and the furnace gas, so as not to break the loop stable furnace atmosphere.
4. explosive devices Reducing gas and air mixture reaches a certain mixing ratio, at a certain temperature can lead to an explosion, so the front of the furnace, the rear chamber, quenching chamber and slow cooling chamber, all with explosion-proof equipment, stove and exhaust gas control systems Measures must be explosion-proof.
5. Refractory No muffle furnace using a reducing gas atmosphere, in order not to affect the life of masonry, as well as normal furnace atmosphere is not broken ring, requiring the use of anti-carburizing furnace refractory masonry. 6
. mechanization and automation level Tightness requirements of various high-atmosphere furnace, loading and discharging operations complex process, requiring a multi-purpose stove, when mass production, composed of large combined heat more dedicated or more dual-use unit, which requires a higher mechanization, degree of automation.
