Product introduction of shaft quenching furnace
Well quenching furnace use:
RJ2 series high-temperature well-type quenching furnace is a national standard energy-saving period-operating well-type resistance furnace with a maximum temperature of 1200 ° C and an operating temperature of 1200 ° C. It is mainly used for alloy steel, high-speed steel, high-manganese steel, high-chrome steel, shafts, pipes, etc. Metal materials and machine parts are used for heat treatment such as normalizing, annealing and quenching in general atmosphere or simple protection. Power 15-4900KW; furnace diameter ¢ 300mm- ¢ 11m, maximum depth can reach 48m.
Structure introduction:

RJ2 series high-temperature well-type resistance furnace structure, the shell is made of steel plate and section steel, and the cylindrical furnace body is sealed by welding. The furnace lining is made of ultra-lightweight 0.6g / cm3 energy-saving vacuum ball refractory bricks (or fiber cotton module). The furnace lining and the furnace shell are sandwiched by an alumina fiber felt for insulation, and the gap is filled with expanded thermal insulation powder. 0Cr27Al7Mo2 high-resistance alloy wire is used for the resistance wire to be spirally installed on the wire resting brick in the furnace. The furnace cover is lifted manually or electrically. If the user proposes the need for atmospheric protection to reduce the oxidation of the workpiece, a stainless steel three-head oil injector can be installed on the furnace cover, and methanol or kerosene is dripped to generate a simple protective atmosphere. A nitrogen gas inlet pipe is installed in the lower part of the furnace and can be accessed. Nitrogen protects or flushes flammable gases to prevent explosions. To ensure safe operation, a limit switch is installed near the lifting mechanism. This switch is interlocked with the power supply of the control cabinet of the high-temperature well type resistance furnace, and the power is turned on when the furnace cover is closed. When the furnace cover is opened, the limit switch cuts off the control power, so the power of the heating element is cut off at the same time to ensure safe operation. The high temperature well type resistance furnace is equipped with an automatic temperature control cabinet and a thermocouple when it leaves the factory.
