3. Electric Heat Treat Furnace Structural Introduction
The pit type furnace is mainly comprised of furnace shell, furnace
lining, heating element, furnace cover, furnace cover lifting
mechanism and electrical control system.
3.1 furnace shell
The furnace body steel structure is made from 6-8# sectional steel
and 3-10mm steel plates.
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.
3.2 lining
The furnace lining material adopts is high quality high temperature
aluminum silicate refactory fiber folding blocks.
The lining is fixed to furnace body by stainless steel fixtures.
The total lining thickness is 350mm.
3.3 heating elements
The furnace employs quality 0Cr25AL5 high temperature alloy belts
as heating elements.
The heating element is retained to the furnace wall through
porcelain nails.
The furnace has 1 temperature zone. And the heating elements are
arranged based on zone arrangement.
3.4 furnace cover lifting mechanism
The furnace cover is welded by 8# sectional steel and 6mm steel
plate.
The heat preservation material of furnace cover is aluminum
silicate fiber folding block. The furnace cover is lifted by crane.
3.5 electrical control system
Temperature control: the furnace adopts Shanghai Guolong
intelligent temperature controller to control the temperature.
Heating zone adopts a strongly damped ammeter which can directly
reflect to heating elements working condition.
The heating control loop has over-temperature alarm and send
sound-light alarm when the heating zone is over-temperature.
