Supply Pit carburizing furnace carburizing furnace

SNRQ3 Series Pit carburizing furnace cycle mode of operation is a new energy-saving heat treatment furnace, mainly for gas carburizing steel parts. As the use of ultra-light saving lining materials and advanced integrated water-cooled furnace blower seal the series carburizing furnace temperature uniformity, fast heating, good insulation, the workpiece carburizing speed, even the atmosphere carbon potential, uniform permeability layer, When the furnace pressure increase, and there is no leakage, improve production efficiency and quality carburizing. Structure: The series carburizing furnace from the furnace shell, lining, lid lifting mechanism, sealed furnace fan, muffle tank, heating element and electrical control system components. Furnace shell made of welded steel plate and steel. Ultra-light saving firebrick lining is made 0.6gcm3 high strength, aluminum silicate fiber, diatomite insulation bricks and masonry from asbestos saving composite structures. Lid lifting mechanism consists of motor, gear pumps and other components, when opening the lid, simply press the button on the control box, the lid that is 30 to 70 mm | sec rise. For safety reasons, the lift shaft provided with two trip switch, when the lid rises, the lower limit switch automatically cut off carburizing furnace control cabinet main circuit power supply, the heating element power to stop working, the upper limit switch are restricted lifting shaft raising the height of the lift pump rises too high to prevent prolapse. Furnace fan seal is mounted on the lid, and the atmosphere inside the tank for stirring muffle uniform composition, while the furnace temperature more uniform. On the lid is also equipped with three muffle furnace process pipe leading to the tank: a three-headed stainless steel casing to the top Install drip by drip into the furnace triceps moisture Note A drunk, kerosene or other organic liquids various liquid can be adjusted, ammonia hole of the sleeve can be used to transport ammonia as carbon, nitriding purposes (without nitriding can use this nozzle closed) to the furnace; a casing for the sampling tube, the upper part of the casing can be connected to a pipe joint "U" shaped glass tube pressure gauge for monitoring furnace muffle furnace tank role is to maintain pressure to ensure normal carburizing or carbon, nitriding, which the heat-resistant steel (casting). The electric heating element alloy wire around the spire, is mounted on the inner wall lining and holding the lead through the lead out of the furnace, carburizing furnace temperature furnace by the insertion of a thermocouple, compensation wire transmits signals through to the automatic temperature control cabinet, temperature cabinet automatic control, adjust and record heating furnace temperature.
