Description
Technical field
This utility model belongs to roaster field, more particularly to a kind of baking furnace flame path wall construction.
Background technology
Ring-form calcining furnace is the large-scale thermal kiln furnace equipment for producing carbon product most critical, to a prebaked anode factory
For, the capital expenditure of ring-form calcining furnace accounts for the 50%~60% of whole charcoal ink factory's gross investment, and Anode Baking Furnace Design and technology
Advanced quality to carbonaceous product, the production capacity of specific investment cost, energy resource consumption, furnace life, production cost have very big
Impact, the design of baking furnace flame path wall construction, the selection of material and construction technology be design roaster most critical technology.

Big to improve, the technical-economic index for enabling ring-form calcining furnace substantially changes, but flue wall is still using fritter brick masonry
Brick technology, the service life that flue wall is present is short, it is big or middle repair time length etc. and perplex the problem of yield and quality still exist.
Different according to flue wall size, per pass wall is about formed by 2000-3000 block brick masonries, and not only the overall structure of furnace wall is strong
Degree is poor, and can only be with being accomplished manually construction operation, it is impossible to realize do mechanization operation, the brickwork time is long, low production efficiency, work
The high labor intensive of people.And the brick-building art of mud is not beaten due to still adopting flush joint to beat mud, vertical seam, brickwork joint mud so occurs
Slurry comes off, and have impact on the overall construction intensity of flue wall.
In addition in process of production, according to technological requirement repeatedly heating, cooling, when filling every time, coming out of the stove, crown block clamp,
Carbonaceous product is all inevitably collided on flue wall, can gradually step into then " furnace box deformation → flame do not follow the correct path →
Temperature produces the dead angle → different parts temperature difference and becomes big → furnace box and further deforms " etc. vicious cycle, cause energy consumption to increase, the body of heater longevity
Life is reduced, light maintenance in occurring frequently.When deformation reaches to a certain degree, must just remove and build again, dismounting is laid equal stress on and builds a quirk

The normal production in workshop also increases difficulty.Because ring-form calcining furnace is operation in a looping fashion, leaves maintenance, dismounting for, build again
The time of flue wall is at full stretch, it is generally the case that be all just must to start to shape when furnace temperature also has 80 DEG C~90 DEG C,
Working environment is extremely severe, certainly will influence whether construction quality again in turn.
At present, China's ring-form calcining furnace flue wall depression, deformation, usage cycles it is short be affect stove production capacity it is main because
Element；The crack of brick flue wall, leak out, stove upper and lower temperature difference also has large effect to product quality greatly；Overhaul time length, apply
Work bad environments are the difficult problems in production management.
