This series of gas nitriding furnaces is a standard energy-saving cycle operation furnace. It is mainly used for gas nitriding heat treatment of various steel mechanical parts, automobile crankshaft, automobile piston ring, motorcycle brake pads, molds, etc. The use temperature is 650℃. RN series well type gas nitriding furnace is an energy saving type gas nitriding furnace, which adopts energy-saving lining double water cooled furnace tank cover, vacuum rubber seal and upper and lower multi-zone temperature control. The electric furnace insulation, furnace temperature uniformity, sealing, nitriding speed have been greatly improved, and the furnace type is consistent with international standards.

Equipment Characteristics

1.By the well type tank nitriding furnace as the main body

using hydrogen analyzer and intelligent instrument for nitrogen potential control, and equipped with nitriding expert system software, the whole process is controlled by computer, process parameters control, high degree of automation, easy to operate.

Electric heating multi-zone synchronous control technology, one button operation again, the whole process record, automatic and efficient completion;

Constant current, constant voltage, constant power control technology, according to different load characteristics, effective protection of power failure caused by damage to the load;

Multiple time curves can be set, and the total number of curves is up to 50 segments;

Two program setting modes of "given value + time value" and "heating section + constant temperature section" are optional;

All parameters can be set by key, and the data is automatically saved without loss;

2.English operation interface

Touch screen integrated control, English interface, simple operation;

3.Furnace body seal

The sealing fan for the all-fiber furnace cover and the integrated air-cooled furnace adopts double sealing for the furnace cover and the furnace mouth. The outer side adopts high temperature resistant silicone strip and the inner side adopts asbestos rope heat insulation to effectively protect the high temperature silicone strip and the gas sealing property is good. The unique design of water circulation cooling system is adopted to effectively protect the sealing silicone strip to ensure its service life.

4. Furnace cover lifting system

The furnace cover lifting adopts electric lifting, simple operation, no hydraulic lifting oil leakage phenomenon.

5. high furnace uniformity

The unique power distribution method is used to ensure that the furnace temperature uniformity meets the process requirements, and the furnace uniformity can reach ±10℃;

6. safety protection device

The overtemperature controller is used to monitor the upper limit temperature in the furnace, and automatically cut off the power supply when overtemperature is reached;

Support to turn off the output when the furnace door switch is off;

7. Intake and exhaust system:

The furnace cover is equipped with sampling tube, exhaust pipe and input tube on the upper side wall of the furnace can be used for ammonia input. The furnace tank and the furnace cover are sealed with water-cooled vacuum rubber and equipped with a compression bolt. The exhaust gas in the furnace is discharged out of the furnace through the exhaust pipe
