3.Structural Introduction
The electric heat treatment furnace is mainly comprised of furnace body,
lining, furnace door and door compression system, bogie, heating
element, and temperature control system.
furnace body:
The electric resistance car bottom 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
for heat treatment of metals is painted with heat resistant paint.
