NST 900°C Hydrogen Atmosphere Furnace



NST 900°C Hydrogen Atmosphere Furnace With UAV Program Temperature Control Instrument

This stainless steel inner hydrogen atmosphere furnace is equipped with a stainless steel inner tank in the furnace. The furnace door is sealed with a silicone O-ring. In order to reduce the O-ring sealing temperature, a water cooling system is installed at the door of the furnace. Thermocouples, intake valves, air outlet valves, pressure gauges, etc. are installed on the inner casing. The furnace is equipped with a hydrogen detector, a burner, a combustion controller, an alarm lamp, an igniter, an explosion-proof valve, and the like. After the gas passes through the flowmeter, it enters and exits from the rear, and the exhaust gas is cooled by the water cooling system and discharged from the furnace door. It can pass gas such as hydrogen, argon, nitrogen, oxygen, carbon monoxide or ammonia. The furnace has the advantages of equal temperature field, low surface temperature, fast temperature rise and fall, energy saving, clean furnace and no pollution. It is an ideal product for universities, research institutes, industrial and mining enterprises to do atmosphere protection and sintering, atmosphere reduction and degreasing.

1, 30-stage program temperature control intelligent PID adjustment.

2. With over-temperature protection, the electric furnace heating circuit is automatically cut off when the temperature is over-temperature or broken, (when the electric furnace temperature exceeds 1200 degrees or the thermocouple is blown, the AC relay on the main circuit will be automatically disconnected, the main circuit is broken. On, the ON light on the panel is off, the OFF light is on, and the limited protection electric furnace).

3, with 485 communication interface (standard when purchasing software)

4, with power-off protection function, that is, when the power is turned on after the power is turned off, the program does not start from the starting temperature, but the furnace temperature rises from the time of power failure.

5, the meter has the function of temperature self-tuning

chamber 1. High-quality high-purity alumina polycrystalline fiber curing furnace formed by vacuum suction filtration.

2. Formed by Japanese technology.

3. The spacing and pitch of the resistance wires in the furnace are all arranged according to the best thermal technology in Japan, and the temperature field is simulated by the thermal software.

4, using 4 sides heating (left and right, four sides), the temperature field is more balanced
