2.Structural Introduction
The bogie hearth furnace manufacturer is mainly comprised of
furnace body, lining, furnace door and door compression system,
bogie, heating element, hydraulic tilting system, and temperature control system.
2.1 furnace body
The bogie hearth furnace price body steel structure is made from 8-10#
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. The furnace door is made of 16mm channel steel and 6mm steel plate.
2.2 lining
The wholesale bogie hearth furnace body is built with an all-fiber system. The lining material used is quality high alumina refractory fiber 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 350mm. The silicate aluminum fiber resists a
maximum temperature of 1360℃. The round steel fixation parts are made
of 304 stainless steel.
2.3 furnace door and door up-down system
The car bottom furnace for sale door is comprised of all-fiber lining and steel
structure casing. The door frame is made of 10mm steel plate and 8# sectional steel. The door is built with high alumina refractory fiber blocks same as that for the furnace body. The overall structure of the furnace maintains its shape while heated. The door edge is made of 10mm steel plate to ensure the strength of the door.
Driving method of door: The furnace door is electrical lifting mechanism.
And it is sealed by spring.
A soft contact sealing structure is arranged between the furnace door and the furnace lining. The fiber sealing block around the furnace door protrudes out of the furnace door lining. The furnace door frame is equipped with thick steel plate. When the furnace door is closed, the hand wheel is used to compress the furnace door to make the sealing fiber block fully contact with the steel plate and seal it. The gap between the furnace door and the steel plate of the furnace door frame is 50mm to ensure smooth movement of
furnace door when opening and closing. The above methods are simple, practical, reliable and easy to maintain.
2.4 bogie
The bogie hearth furnace for pressure vessel is comprised of bogie frame, wheels, refractory bricklaying body, Cr25Ni20 heat resistant bogie face plate,
heating elements, and bogie driving mechanism.
bogie structure: the bogie frame is made from 12# 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.
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.
bogie face plate: 30mm thick Cr25Ni20 heat resistant steel casting part with 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 the push rod compression mechanism. The sealing between the bogie and the furnace body is through the abnormal-shape bricks and fiber blocks. When the door is closed, there is a second sealing by the aluminum fibers which contact tightly with the furnace door.
2.5 heating element
The heating element: The 0Cr27AL7Mo2 resistance corrugate shape alloy resistance strips are mounted in 2 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 1 heating zone. All lead-out conductor bars are made of φ16 0Cr25AL5 material.
2.6 hydraulic tilting system
The electrical bogie hearth furnace has tilting function which is realized by hydraulic
system. The front part of the bogie hydraulic is equipped with hydraulic station.
Two oil cylinders are equipped under the bogie. The tilting function is carried out
by a special hydraulic system. The furnace body is installed with a safety device,
which can avoid overturning.
2.7 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 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.
Each heating zone is independently controlled for start and stop. And there are also both manual and auto control mode available.
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.
