Description
Technical field
The present invention relates to refractory material production field, more particularly to cement kiln refractory brick.
Background technology
Cement kiln is developed with parapet brick, is broken and is used castable method for many years.Castable stomata is big, intensity difference, and uses
Short life, while influence rotary kiln normal operation and yield.It is serious up to production loss to company, it is big often to repair labor intensity.And
And castable due to structural rigidity itself it is poor, anti-seismic performance is weak, and long-term use easily causes material body and come off, and pours difficulty during maintenance
Degree is also big, and no general masonry of the image of Buddha equally piles up shaping, has much room for improvement.
The content of the invention
It is simple in construction in view of the deficiencies of the prior art, the present invention provides a kind of compound brick body, high-temperature resistant anti-shock effect
It is good, service life length, and overhaul conveniently, shaping can be piled up as general masonry, enormously simplify operation difficulty, improves water
The cement kiln parapet brick of mud rotary kiln service life.
To realize the object of the invention, there is provided following technical scheme：Cement kiln parapet brick, it is characterised in that including square
Matrix, described matrix include the basic unit at center and are arranged at the thermal insulation layer of basic unit top and bottom, are arranged at thermal insulation layer outer surface
Antidetonation layer and the working lining for being arranged at antidetonation layer outer surface, the antidetonation layer surface offer square groove, fill out and cover in groove
There is refractory wool, described matrix surface offers symmetrical 4 insertions square hole two-by-two, is equipped with square connecting rod in square hole, leads to
Cross square connecting rod adjacent cement kiln is connected with parapet brick matrix, the groundwork thickness is 15mm ~ 15.5mm.
Preferably, basic unit, thermal insulation layer, antidetonation layer and the equal high temperature crimping of working lining are fixed.High temperature crimping is the present invention
Another key problem in technology, overcome prior art using binding agent connection shaping can be easily separated the problem of coming off, substantially increase
Service life, and moulding process is simple, reduces cost of manufacture, the technique of matrix high temperature crimping is those skilled in the art's
Common knowledge, specific introduction is not done.
Preferably, the basic unit is composite mullite layer.
Preferably, thermal insulation layer is the aluminosilicate property layer of low heat conduction.
Preferably, antidetonation layer is silicon carbide layer.
Preferably, working lining is wear-resistant ceramic layer.
The selection of above layers material show that the performance of material more similar than other is higher by least 20% by long-term experiment,
Improve service life and quality.
Preferably, the antidetonation thickness degree is the 1/2 of groundwork thickness, thermal insulation layer and working lining thickness are the 1/ of basic unit
3.The selection of thickness be by working environment come selection, it is big while performance is improved by matching the thickness of above layers
Cost is saved greatly.
Beneficial effect of the present invention：Present invention success is convenient in Subscriber Unit test construction, resistance to erosion.Overall structure is stable,
So as to improve productivity effect for cement rotary kiln production, service life is extended.The technical indicator of brick body of the present invention：（1）Volume
Density >=2.65g/cm3 apparent porosities≤18% compressive resistance >=100Mpa refractoriness under load >=1600 DEG C .Al2O3 >=65
SiC≥10% 。
