Use
ZRJ3 series release vacuum protect atmosphere stove whether
energy-efficient high accuracy control the temperature well cycle
homework stove in advance. Used in spaceflight , aviation flying
machine manufacturing mainly, the accurate part is too bright to
oxidize and return dealing with burning hot , and automobile
manufacturing, precision optical machinery manufacturing industry,
accurate parts or forging bright to is it is it take off carbon
heat , quench , anneal , flash back heat treatment and whom ball
anneal spend to oxidize to have. The products accord with the
military standard GjB509-98-88I heat treatment resistance furnace
of Ministry of Industry of China's aviation .
Brief introduction of structure
ZRJ3 releases the vacuum to protect the atmosphere stove in
advance, is made of stencil plate one the well type stove outer
covering mainly, the section steel group welds and makes the body
structure of the stove . The furnace wall adopts the
energy-conserving refractory brick of little pearl of 0.6g/m3 ultra
light quality, insert and put the aluminium fibre felt of silicic
acid among furnace wall and stove outer covering, it is the
energy-efficient furnace wall of model that the space packs and
expands the vermiculite and plays the part of and keeps warm,
economize on electricity by 30-60%, the electric heat component
adopts and seeks unity of standard and able to bear the ultra warm
high-temperature resistance wire ocr25A15 or ocr27AL7M02 new-typly
both at home and abroad; Resistance wire is 5 years of warranty,
the vacuum pot adopted lcrl 8Ni9Ti stainless steel board one to
make , adopts and protects welding automatically and densly,
detected a flaw and tried pressing and making by large-scale mere
flaw detection room x of our factory. The stove keeps the stove
warm to cover while covering and adopting the stainless steel, the
stove overlays the panel and pot body and adopts the vacuum rubber
of dark pair of water-cooling to seal, the electric stove stove of
the above-mentioned 60kw covers and installs vacuum sealed
stainless steel air blower, can make the temperature in the pot
even , stove panel installation is it release vacuum interface , is
it protect atmosphere interface , vacuum manometer to give to have.
Stove overlay with stove pot driving a vehicle by workshop pot is
it appear naturally empty and cold to hang or pond force the speed
to be cold whole vacuum, in order to load and unload the work
piece. In order to improve production efficiency , can order two
vacuum pots and work continuously alternativly . Can be up to the
natural cooling of stove . 60Kw above electric stove divide into
two district or many district control the temperature from head to
foot, according to intensify law district power is it greater than
go to district power to assign. Adopt two or the electric cupboard
of silicon controlled rectifier of many microcomputers procedure to
control the temperature, and show automatically that surveys
furnace temperature, calculate and intensify temperature value of
the slope and establishing value, the operation exporting value of
power of freedom, exceed the curve record of the warm warning and
automatic craft . Unless it can make curve , it control the
temperature precision 1.5 degrees Centigrade of soils,. In order to
be used as the ball annealing, the technological requirement has
780 degrees Centigrade while cooling in 680 degrees Centigrade of
fast stoves , should propose , install additional stove hot
nitrogen is it get stove nitrogen is it connect hot to reduce
nitrogen after the temperature to circulate fast to take out while
ordering, the cold nitrogen enters the cold circulatory system soon
of pot.
