2.Structural Introduction
The bogie hearth furnace is mainly comprised of furnace shell, lining, furnace door and door compression system, bogie and bogie traction mechanism, sealing between furnace body and bogie, heating element and fixtures, temperature control system.
2.1 furnace body
The stress relieving car bottom furnace shell is welded with steel plate, the thickness of steel plate ≥3mm.
2.2 lining
The quenching car bottom furnace body is built with an all-fiber system.
2.3 furnace door and door up-down system
The quenching bogie hearth furnace door is comprised of all-fiber lining and steel structure casing. The door frame is made of 10mm steel plate.
Driving method of door: The furnace door is electrically lifted upward and downward by the hoist. And it is sealed by spring.
2.4 bogie, 1 set;
2.5 heating element
heating element: The 0Cr25AL5 resistance corrugated shape alloy resistance strips are mounted in 2 side walls.
2.6 electrical control system
Temperature control: The control actuation system is a large-power triggering one complete with a radiator and an air cooling system. There is also an air switch.
The heating loop is equipped with ammeter, voltmeter, heating element on-off indicator, power-on interlock protection,and safe earthing measures.
Movement control: The control system mainly controls the door up-down movement, door compression, and door in-out movement. Also the movements are necessarily linked to ensure the operation safety.
