Features：

- The well type gas carbonitriding furnace is composed of a furnace shell, a furnace lining, a furnace lid lifting mechanism, a vacuum sealing fan, a muffle tank and a heating element. The furnace shell is round and is welded from steel plates and sections. The furnace lining is an energy-saving furnace lining structure made of 0.6g/cm3 high-strength ultra-light micro-bead vacuum ball energy-saving refractory brick, aluminum silicate super long fiber, and expanded thermal insulation pellets. The vacuum-sealed fan is mounted on the furnace lid, which agitates the atmosphere in the muffle tank to make the composition uniform and at the same time makes the furnace temperature uniform.

- There are three pipes in the furnace cover, which are directly connected to the carbon-nitrogen-resistance resistance furnace. One pipe is equipped with three stainless steel drip chambers. The three drip chambers are used to inject the drunken and kerosene into the carbonitriding furnace. Or other organic liquids, various liquids can be adjusted, the ammonia pores on the tube can be used to input ammonia into the co-infiltration furnace for carbonitriding (the nozzle can be sealed when no nitriding), one of the tubes For the sampling tube, the upper part of the tube has a tube nozzle connected to a "U" type glass tube pressure gauge for monitoring the pressure of the atmosphere in the resistance furnace, and the tube nozzle at the lower part of the exhaust tube can be connected with the carbon dioxide infrared meter to For controlling the furnace gas, the cap portion of the tube has a function of adjusting the deflation and adjusting the pressure in the carbonitriding furnace, and the exhaust gas discharged from the nozzle should be burned off at a point, and the flame discharged is 200 mm to 300 mm. good. The three pipes on the above-mentioned furnace cover have water-cooling sleeves for rapid cooling of the gas entering the three pipes. The function of the muffle tank is to maintain the furnace pressure and ensure the normal progress of carburizing or carbonitriding. Made of steel. The carbonitriding furnace is equipped with a cooling bucket for storing the processed parts and a sand sealing groove at the furnace cover.
