pit type quenching furnace briefly:
RJ2 series pit type quenching furnace is a national standard energy-saving batch type heat treatment furnace, the heat treatment temperature can reach 850 ℃ - 1200 ℃, mainly used for bar, long shaft, roll, 45 steel, stainless steel and other metal materials and mechanical parts for quenching heat treatment. The workpiece is hardened vertically, which is not easy to deform.
pit type quenching furnace structure:
The well type furnace is mainly composed of furnace shell, furnace lining, heating device and temperature control device. The furnace body is a cylindrical deep well. The workpieces are vertically installed in the furnace for heating. The well type furnace is usually placed in the workshop in the ground plane, and is also placed above the ground plane, or the ground of each half layer has ups and downs.
Pit furnace can also be used for tempering, annealing, normalizing, carburizing and carbonitriding heat treatment of mechanical parts. It can be heated by electricity or gas. It is called pit resistance furnace with electricity as heat source. It can form a complete set of heat treatment production line with pit tempering furnace, quenching tank, cleaning machine and other equipment.
