RJ2 series of high temperature pit furnace is the national standarded energy-saving cycle operations pit furnace, the temperature of 1200℃ rated, mainly for steel, high-speed steel, high manganese steel, high chrome steel, Shaft, pipes and other metal materials and machinery parts in the general atmosphere or simple protection for normalizing, annealing, with heat treatment, such as quenching. Power 15-4900KW; Furnace diameter is ￠300mm-￠11m, the largest to reach 48m depth.

Structure description:
RJ2 series of high temperature pit furance structure, the shell are welded by steel plate and steel cylindrical furnace, all of them are used in all enclosed welding. Lining using ultra-light 0.6g/cm3 energy-saving vacuum insulation ball refractory brick building. Lining home with the furnace shell laminated aluminum mat acid insulation, insulation powder expansive space filled. Resistance silk used 0Cr27Al7Mo2 high resistance alloy wire around the spire installed in the furnace of dormant Wire and Bricks. Lid using manual or electric movements. If users need to protect the atmosphere workpiece reduce oxidation, can be installed in a stainless steel lid three Pentanes injection, infusion methanol or kerosene, to produce simple protective atmosphere, in the lower part of the furnace installation of nitrogen gas pipeline, nitrogen-protection or washed out into the flammable gas to prevent an explosion accident. To ensure safe operation in the vicinity of lifting bodies with limit switch, the switch with the high temperature resistance furnace control cabinet Well Interlocking power, lid-power shutdown. When the lid is opened time-switch control to cut off power supply, heating elements at the same time cutting off the power supply to ensure safe operation. Well-type high temperature resistance furnace factory supporting automatic temperature control cabinet, thermocouple.
