Bogie Hearth Furnace

1. Application

The RT3-580-6 electrical bogie hearth furnace is mainly used for heating,

decontamination and cleaning of pipes.

2. Structural Introduction

The bogie hearth furnace is mainly comprised of furnace body, lining,

furnace door and door compression system, bogie, heating element,

circulation device and temperature control system.

2.1 furnace body

The bogie hearth furnace body steel structure is made from 10-14#

sectional steel and ≥4mm steel plates. The side pillar and back pillars

are made from sectional steel, and are reinforced with sectional steel

bracings. The external wall of the furnace is painted with 2 layers of

primers, and 2 layers of coating paint. The key part of the furnace is

painted with heat resistant paint.

2.2 lining

The wholesale bogie hearth furnace body is built with an all-fiber system.

The lining material used is quality aluminum fibers fixed by round steel parts.

The aluminum fibers are pre-compressed into blocks (compression gravity:

≥230Kg/m3 ) and then fixed to the furnace body by round stainless steel parts.

This refractory lining structure has the advantages of low heat conductivity,

strong anti-shock capacity, and anti-erosion. The lining has a total thickness

of 240mm. The silicate aluminum fiber resists a maximum temperature of 1000℃.

2.3 furnace door and door up-down system

The car bottom furnace price door is comprised of all-fiber lining and steel

structure casing. The door frame is made of 10mm steel plate and 12mm

sectional steel. The door is built with silicate aluminum fiber blocks same

as that for the furnace body. The overall structure of the furnace maintains

its shape while heated.

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

The bogie is comprised of bogie frame, wheels, refractory bricklaying body,

heat resistant bogie face plate, heating elements, and bogie driving mechanism.

bogie structure: the bogie frame is made from 14# beam and 10mm steel plates.

The bogie could work for a long time without deformation at full load.

wheel: The wheels are made from ZG55# steel casting. The transmission

shaft is made from 45# steel, and it is heat treated. The transmission bearing

is of the heavy type pillar bearing to bear the weight. There are a total of 6

pairs of wheels, and each wheel is of diameter 300mm. One pair of driving

wheels and five pairs of driven wheels.

bricklaying body: The bogie is built with a combination of high alumina

refractory bricks, light refractory bricks, and heat preservation bricks. The

bricklaying body of the bogie has heating elements installation slot for easy

installation of the heating elements. The impacted parts and weight bearing

area are bricked especially with heavy type high aluminum refractory bricks.

There is also free space left for the refractory lining expansion when heated.

Sealing method of furnace door: The fiber sealing block is equipped between

furnace door and furnace lining. When furnace door closing, the roller on the

both sides of the furnace door will go down along the track. And there is a ramp

at the bottom to make sure the furnace door is closed tightly. The angle of the

ramp is adjustable by the screw. (please see 3 pictures below)

2.5 heating element

heating element: The 0Cr27AL7Mo2 resistance spiral-shape alloy resistance

strips are mounted in 5 side walls, two side walls, back wall, furnace door and

bogie bottom. The resistance strips are produced through special molds, and

are installed in the furnace wall by porcelain nails. And there is a porcelain

gasket between the fiber wall and the resistance strips to avoid short-circuit.

There are 6 heating zones. All lead-out conductor bars are made of φ16

0Cr27AL7Mo2 material.

2.6 electrical control system

Temperature control: the furnace adopts Shanghai Guolong intelligent temperature

controller to control the temperature which has self-tuning function to calculate

the ideal PID parameter and achieve a temperature stability. The temperature

controller has the functions of over-temperature alarm and thermal couple breakage

protection.

The car bottom furnace design has 6 temperature control zones for controlling

the linkage between the temperature and the motor movements. Each zone is

set with an over-temperature alarm. The heating loop adopts the double-direction

SCR and trigger control. The power is regulated in the time proportional regulation

manner.

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.
