RJ2 series Mid-temperature pit Furnace is the national standarded energy-saving cycle operations Pit Furnace, mainly for steel parts, Shaft, pipes and other metal materials and machinery parts in the general atmosphere or simple protection for normalizing, annealing, quenching, and other heat treatment used.
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. In order to make uniform heating workpiece, medium and large pit furnace temperature control sections, in accordance with the air temperature rise of temperature wire arrangement method used reasonable distribution of power, the furnace temperature from top to bottom in order to ensure uniform consistency. To ensure safe operation, in the vicinity of body movements with limit switch, the switch and power control cabinet Well furanceInterlock, lid closed when connected to power. 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. Mid-temperature pit Furnace supporting automatic temperature control cabinet, thermocouple.
