3. Structural Introduction
The RT3-320-6 bogie hearth furnace is mainly comprised of
furnace body, lining, furnace door and door lifting mechanism,
furnace door compression mechanism, bogie and drawing mechanism,
seal between furnace body and bogie, heating element and fixed
device ,
furnace temperature automatic control system.
lining
The high temperature 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
260mm. The silicate aluminum fiber resists a maximum temperature of
100℃.
Hot air circulating system:
The heat treatment furnace is mainly comprised of three axial flow
fans in the furnace.
The heat emitted by the heating element is evenly blown to the
effective working area
by the circulating fan through the wind guide plate. The air guide
plate is made of 1Cr18Ni9,
and the fan and shaft are made of 1Cr18Ni9Ti. In order to ensure
the normal use of bearings,
the cooling method is air cooling.
