furnace body
The furnace body steel structure is made from 10-12# 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.
lining
The 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 350mm. The silicate
aluminum fiber resists a maximum temperature of 1260℃. The material
of round steel fixation parts is 1Cr13.
Heating Element
The 0Cr27AL7Mo2 resistance spiral-shape alloy resistance strips are
mounted in 2 side walls, back wall,
furnace door and bogie bottom of the bogie hearth furnace. 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 2 heating zones.
All lead-out conductor bars are made of φ16 0Cr27AL7Mo2 material.
