Electric Resistance Heat Treatment Furnace Bogie Hearth 1200×600×450mm

1200×600×450mm Electrical Bogie Hearth Furnace


1.Application

The RT2-45-9 electric bogie hearth furnace is mainly used for heat

treatment of steel structure parts, cast steel parts, shaft bar parts,

tool steel products, etc.


2. Structural Introduction

The RT2-45-9 bogie hearth furnace is mainly comprised of furnace body,

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

and temperature control system.


2.1 furnace body

The car bottom furnace price body steel structure is made from 8-12#

sectional steel and ≥3mm 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 car bottom furnace design 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 300mm. The silicate aluminum fiber resists a maximum temperature of

1100℃. The material of round steel fixation parts is 1Cr13.


2.3 furnace door and door up-down system

The high temperature trolley type furnace 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 10# 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 2

pairs of wheels, and each wheel is of diameter 240mm. The bogie is motorized.

And the driving motor is equipped with a braking speed reduction device to

relieve the inertia at the start-up and stop movement. There are 2 limit

switches to avoid over-travel of the bogie.


bricklaying body: The bogie is built with a heavy 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.

bogie face plate: 30mm thick CrMnN heat resistant steel casting part with

max working temperature≤1200℃. It can prevent scales from falling into the

heating elements slot which would form a short circuit.

bogie moving mechanism: The bogie has a self-moving method. The reducing

gear drives the bogie wheel to move. The bogie movement is smooth and stable.

Sealing among furnace door, furnace body and bogie: Sealing between

the furnace door and the furnace body is through spring. The sealing between

the bogie and the furnace body is through soft special shape bricks and fiber

cotton block.


2.5 heating element

heating element: The 0Cr25AL5 resistance spiral-shape alloy resistance strips

are mounted in 2 side walls. 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 1 heating zone. All lead-out conductor bars are made

of φ16 0Cr25AL5 material.


2.6 electrical control system

Temperature control: the furnace adopts Changzhou Huibang 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 annealing car bottom furnace has 1 temperature control zone 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.
