3. Structural Introduction
The bogie hearth furnace is mainly comprised of furnace body, lining, furnace door and door up-down system, bogie,
heating element, and temperature control system.
3.1 furnace body
The furnace body steel structure of the bogie hearth furnace is made from 10-12mm sectional steel and 4mm 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 car bottom furnace is
painted with heat resistant paint.
The lining material used is quality high 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 stainless steel parts. This refractory lining
structure has the advantages of low heat conductivity, strong anti-shock capacity, and anti-erosion. The lining layer total thickness
The silicate aluminum fiber resists a maximum temperature of 1250℃. The round steel fixation parts are made of 304 material.
