bogie hearth furnace

bogie hearth furnace large-size fuel oil type bogie hearth furnace (heat treatment furnace) All fiber lining; complete sealing of the furnace body, automatic control over each medium; automatic control of the furnace pressure, imported or domestic nozzle; PLC distributed control system. Application: annealing treatment of metal workpieces or forge pieces at rolling mills.Rated temperature: 700 degree——1100±10 degree, control accuracy: ≤±1 degree.In strict accordance with the environmental requirement of the state. It has met the environmental requirement for special type furnaces. Its firing control system is equipped with imported or domestic quality high speed burner with ejecting speed of 100s/m. The furnace door is opened up-down or moved right-left. The upper cross arm of the furnace door is equipped with worm reducing gear, double chain wheel, plate chain, and gantry support balance block structure. Also a double up-down whole fiber guiding rail sloping block presses hard on the furnace door.The bogie driving is made through the self-moving mechanism of shield gear type or bevel wheel type. The bogie and the furnace body are sealed through electrical or pneumatic pressurizing device. The furnace is one light framework. The annealing furnace is made of quality whole fiber lining, and the forging heating furnace of combined zirconium fiber lining. It has the advantages of light weight, good heat insulation and temperature rise of the outer wall of the furnace body ≤50 degree.The air pre-heating device preheats the heat recycling device. The furnace pressure is regulated through pressure transmitter and smart meter. The valves are controlled automatically and fire is controlled automatically. Its emission of fume meets the state environmental requirement. Temperature control method: 3 methods, including upper industrial computer distributive control; imported smart temperature control instrument; Siemens PLC control and manual control.
