Pit Gas Nitriding/Nitrocarburizing Furnace

The equipment is suitable for hard nitriding and nitrocarburizing of materials such as tool steel and gears

Maximum operating temperature up to 650 °C, 850 °C (for stress relief annealing or nitrogen removal)

Sealed circulation fan, good gas tightness;

The furnace tank is made of corrugated steel with heat-resistant and corrosion-resistant steel plate, and the bottom is welded by cold stamping head

High-purity all-fiber cotton lining or lightweight refractory brick lining;

The heating element may be selected from a resistance wire or a resistance tape

Meet the national standard of heat treatment equipment, the measured temperature uniformity is ±3 °C

The hydraulic cylinder or the pneumatic cover lifting device is used to realize automatic pressing and automatic steering of the furnace cover

Adopt imported multi-loop temperature control system, the main control thermocouple in the furnace tank, the auxiliary control outside the tank, with the program platform waiting to ensure the holding time

Optional batching frame, rapid cooling device to ensure that the furnace temperature is rapidly cooled to below 150 °C, the workpiece is not discolored

Sound and light alarm, air source pressure, cooling water pressure, furnace pressure monitoring alarm, program end alarm

The nitrogen potential control adopts German imported hydrogen probe, nitrogen potential control software and automatic flow control cabinet

The ammonia gas cracking device is used to automatically adjust the nitrogen potential in the furnace

The exhaust gas secondary decomposition device ensures that the ammonia gas can be fully burned at any time (patented technology)
