1. Application

The gas fired bogie hearth furnace is mainly used for heat treatment of metal parts.

2. Structural Introduction

2.1 furnace body

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

steel and 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 main material of the furnace lining is the composite refractory fiber

folding block containing zirconium and chromium at the long-term service

temperature of 1250℃. This refractory lining structure has the advantages

of low heat conductivity, strong anti-shock capacity, and anti-erosion. Aluminum

silicate fiber compression block with thickness of 300mm is designed as the

high temperature refractory layer.

2.3 bogie

The bogie is comprised of heat preservation material, bogie frame and moving

mechanism. The refractory layer is divided into 3 sub-layers, i.e., 1st top

high-alumina brick layer, and 2nd and 3rd layer with both light clay bricks.

The bogie framework is made of 12# I-beam and 12# frame beam. The bogie

has enough rigidity to ensure no deformation under full load operation. The gap

between the two sides of the furnace bogie and the frame of the fire-resistant

trolley should be fixed.

The bogie surface plate is made of 10 mm high quality steel plate. The function

is to disperse the bogie load (make the load distributed evenly) and enhance the

frame rigidity.

The heat preservation material is divided into 3 layers, the top layer being

high-alumina bricks, and 2nd and 3rd layer being both light clay bricks.

The bogie traction mechanism: the trolley traveling mechanism is driven by AC

motor reducer, and the driving mode is reducer sprocket structure. The trolley

goes in and out of the furnace through the reducer sprocket in the transmission

device and the traveling wheel under the trolley to drive the trolley traveling sprocket

to mesh and drive the trolley traveling, which is stable and reliable.

The fire-resistant fiber sealing block is used for the sealing between bogie and the

furnace body, which is pressed by the lever of the electric cylinder and linked

with the electric cylinder of the furnace door. When the bogie is in the right position,

the electric cylinder drives the lever to lift up the fire-resistant fiber cotton sealing

block and push it to the gap between the bogie and the furnace body. At the same

time, the furnace door falls, and the electric cylinder acts to push the furnace door

tightly. If the bogie is discharged, the furnace door will be powered at the same time,

the electric cylinder of the trolley moves to put down the sealing block, the door rises

to the right position, and the trolley can start. The above action can be manual or

automatic continuous action. It is safe to use and convenient to maintain.
