The structure of the series carburizing furnace by furnace shell, lining, lid lifting mechanism, sealed furnace fan, muffle tank, heating elements and electronic control systems and other components. Furnace shell made of welded steel plate and steel. Lining is 0.6g / cm3 energy-saving high-strength ultra-lightweight refractory bricks, ceramic fiber, asbestos board diatomite insulation bricks and masonry from energy-saving composite structures. Lid lifting mechanism consists of motor, gear pumps and other components, when the lid is opened, simply press the button on the control box, the lid that is to speed 30-70 mm / sec to rise. For safety reasons, the lift shaft fitted with two limit switches, when the lid rises laboratory furnace, 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 is elevating shaft rising height limit, to prevent excessive rises lift pumping prolapse. Furnace blower mounted on sealed lid, stir and make it available for the tank atmosphere muffle uniform composition, while the furnace temperature more uniform. On the lid is also equipped with three root canal process leading to muffle furnace tank: a three-headed stainless steel casing top Install drip by drip triceps inject moisture into the furnace A drunk, kerosene or other organic liquids , various liquids can be adjusted, ammonia holes on the sleeve can be used to transport ammonia as carbon, nitrogen permeation purposes (without nitriding can use this nozzle closed) to the furnace; a casing for sampling tube, the upper part of the casing can be connected to a pipe joint "U" shaped tube manometer for monitoring tank furnace muffle furnace pressure role is to maintain and ensure the normal or carbon carburizing, nitriding, which from heat-resistant steel (casting). By an electric heating element alloy wire around the spire, is mounted on the inner wall lining and leads to holding the lead through the furnace tube furnace, carburizing furnace temperature by thermocouples inserted into the furnace, the signal is transmitted through a wire to compensate for automatic temperature control cabinet laboratory furnace, automatic temperature control cabinet, adjust and record the temperature of the furnace heating. Carburizing furnace equipped with a cooling barrel (optional), used to store the parts treated with sand seal groove on the lid. High-temperature furnace, furnace, laboratory furnace provided by Longkou Longkou Furnace experiment. Longkou experiment Furnace (www.lk-dianlu.com) strong, credible, in Yantai, Shandong electric equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Longkou laboratory furnace and you hand into the brilliant, for a better future!
