Abstract
A lower wall brick for a cement kiln comprises a square base body. The base body comprises a base layer in the center, insulating layers arranged on the upper surface and the lower surface of the base layer, anti-seismic layers arranged on the outer surfaces of the insulating layers and working layers arranged on the outer surfaces of the anti-seismic layers; square grooves are formed in the surfaces of the anti-seismic layers, high-temperature-resistant cotton is filled into the grooves in a covering mode, four through square holes which are symmetrical two by two are formed in the base body surface, square connecting rods are arranged in the square holes in a penetrating mode, adjacent base bodies of the lower wall bricks for the cement kilns are fixedly connected through the square connecting rods, the thickness of the base layer ranges from 15 mm to 15.5 mm. The composite brick body is simple in structure, good in high-temperature-resistant and anti-seismic effects, long in service life, convenient to maintain and capable of achieving pile forming like ordinary bricks, greatly simplifying operation difficulty and prolonging the service life of cement rotary kiln.
Description
Technical field
The present invention relates to refractory material and make field, particularly relate to cement kiln refractory brick.
Background technology
Cement kiln parapet brick exploitation, breaks and uses castable method for many years.Castable pore is large, intensity difference, and service life is short, affects rotary kiln simultaneously and normally runs and output.Reach company and produce loss seriously, often maintenance labour intensity is large.And castable due to structural rigidity own poor, anti-seismic performance is weak, and Long-Time Service easily causes material body to come off, and it is also large to build difficulty during maintenance, cannot pile up shaping, have much room for improvement as general masonry.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of composite shaped block body, structure is simple, high-temperature resistant anti-shock is effective, long service life, and maintenance is convenient, can pile up shaping as general masonry, enormously simplify operation easier, improve the cement kiln parapet brick in cement rotary kiln service life.
For realizing the object of the invention, provide following technical scheme: cement kiln parapet brick, it is characterized in that comprising square matrix, described matrix comprises the basic unit at center and is arranged at the thermal insulation layer of basic unit top and bottom, be arranged at the antidetonation layer of thermal insulation layer outer surface and be arranged at the working lining of antidetonation layer outer surface, described antidetonation layer surface offers square groove, fill out in groove and be covered with refractory wool, described matrix surface offers 4 symmetrical between two through square holes, square connecting rod is equipped with in square hole, by square connecting rod, adjacent cement kiln parapet brick matrix is connected and fixed, described groundwork thickness is 15mm ~ 15.5mm.
As preferably, the crimping of basic unit, thermal insulation layer, antidetonation layer and working lining equal high temperature is fixing.High temperature crimping is another key problem in technology of the present invention, overcome the problem that prior art utilizes the shaping easy separation of binding agent connection to come off, substantially increase service life, and moulding process is simple, reduce cost of manufacture, the technique of matrix high temperature crimping is the common practise of those skilled in the art, does not do concrete introduction.
As preferably, described basic unit is composite mullite layer.
As preferably, thermal insulation layer is the aluminosilicate property layer of low heat conduction.
As preferably, antidetonation layer is silicon carbide layer.
As preferably, working lining is wear-resistant ceramic layer.
The selection of above-mentioned each layer material is all drawn by long-term experiment, and the performance of material more similar than other exceeds at least 20%, improves service life and quality.
As preferably, described antidetonation layer thickness is 1/2 of groundwork thickness, and thermal insulation layer and working lining thickness are 1/3 of basic unit.The selection of thickness is selected by working environment, by the thickness of the above-mentioned each layer of proportioning, carrying high performance while, has greatly saved cost.
Beneficial effect of the present invention: the present invention's success is convenient at Subscriber Unit test construction, resistance to erosion.Overall structure is stablized, thus is cement rotary kiln production raising productivity effect, extends service life.The technical indicator of brick body of the present invention: (1) bulk density >=2.65g/cm3 apparent porosity≤18% compressive resistance >=100Mpa refractoriness under load >=1600 DEG C .Al2O3 >=65SiC >=10%.
