Equipment description and technical proposal
The RJ2-45-9 pit type annealing furnace is comprised of furnace
shell, furnace lining, heating element,
furnace cover, electric control system and temperature automatic
control system.
1 Furnace shell
The furnace shell is made from 10# ~12# sectional steel and the
furnace bottom plate
thickness is 6mm . The shell has enough strength and rigidity so as
to bear the weight of the workpieces.
2 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.
3 Heating elements
The furnace employs quality 0Cr25AL5 high temperature alloy belts
as heating elements.
The porcelain bolts and gaskets are of corundum material sintered
under high temperature.
The furnace has 1 temperature zone.
4 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.
5 Muffle tank
The muffle tank is made from 6mm 321 stainless steel plate. It is
placed in the furnace hearth.
6. temperature control system
The furnace inside temperature is controlled by the intelligent
temperature controller through PID regulation. The heating control
is through SCR control. Each heating zone is set with one
over-temperature alarm. The audible and visual over-temperature
alarm would be activated if one zone temperature is over the limit.
Electrical control cabinet: the cabinet is made according to
industrial standard, and all wire numbers are clearly printed.
