Pit-type nitriding furnace is of circular structure. The furnace body is made of refractory bricks to reduce heat loss and save energy. Pit-type nitriding furnace adopts heat-resistant steel fan, high temperature and long life.

Pit-type nitriding furnace adopts electric heating method, the temperature of heating chamber, ammonia decomposition rate and other heat treatment parameters are dynamically controlled by high-precision instruments and sensors, with high precision and stable parameters. The pit-type nitriding furnace of Fengdong Heat Treatment adopts electric screw elevator structure, water-cooled jacket and silicone rubber sealing device to ensure that the gas in the furnace does not leak out. The nitriding furnace adopts the design of zone heating, dividing the furnace body into two zones, upper and lower, for heating. Pit-type nitriding furnace through the medium flow control system and furnace pressure detection device control; furnace atmosphere and pressure to ensure that the process parameters.

Application of Pit-type Gas Nitriding Furnace

Pit-type gas nitriding furnace is mainly used for gas nitriding of carbon steel parts, mold quenching and other heat treatment purposes. The equipment is equipped with a drip device, can also be gas nitriding carbonitriding (soft nitriding) treatment. It can be used as a general pit-type tempering furnace when ammonia gas and dripping device are not used.
