Bogie Hearth Heat Treating Car Bottom Furnaces
Equipment Electric 1 Zone 2400×1700×1300mm
1. Company Introduction
Our company is a professional heat treat furnace supplier. We have various
heat treatment furnaces such as mesh belt furnace, pit type furnace, electric
heat treatment furnace, gas fired heat treat furnaces,box type resistance
furnace, steel wire annealing furnace, etc. Speaking of car bottom furnaces,
we have gas fired type and electrical resistance bogie hearth furnaces. The furnace
could be 1 door type, or 2 door type. The furnace bogie could also be of tilting type.

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 quneching car bottom furnace body is built with an all-fiber system.
2.3 furnace door and door up-down system
The quneching 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.
