Main Features
RJ2-200-9 Pit Type Electric Resistance Annealing Furnace is comprised of furnace body, furnace cover, heating elements, electric control system and temperature automatic control system.
furnace shell
: The furnace shell is made from 10# ~12# sectional steel and the furnace bottom plate thickness is
6mm .
Lining
: The furnace lining is all fiber structure which are fixed to the furnace body by stainless steel
fixtures. The total lining thickness is 320mmm, including 300m pre-compressed fiber block and 20mm
backer cotton.
Heating element:
The furnace employs quality 0Cr25AL5 high temperature alloy belts as heating elements. The
heating element is retained to the furnace wall through porcelain nails.
Furnace cover: The furnace cover is made of 12# U-steel and 6mm steel plate. The heat preservation material adopts
aluminum silicate fiber compression block and it was fixed by stainless steel pieces. The opening
method of the furnace cover is by crane. The furnace cover is sealed by sand.
Muffle tank: The muffle tank is made 321 stainless steel plate. It is placed in the furnace hearth. The
cover and bottom of the furnace body are both pressed into shape. The upper part of the furnace body issurrounded by a stainless steel sand sealing groove. And there is an all fiber furnace cover outside the
furnace body so as to form double insulation and seal. So that the energy saving and prevent oxidation
effect has been improved greatly.
over-temperature alarm. The audible and visual over-temperature alarm would be activated if one
zone temperature is over the limit.
