Technical field
The invention belongs to technical field of refractory materials, and in particular to kilneye castable after a kind of cement rotary kiln.
Background technique
New type nonaqueous cement rotary kiln has the characteristics that kiln temperature is higher, kiln is fast faster, alkali corrodes exacerbation, structure is more complicated,
Traditional cement kiln refractory is no longer satisfied the use of new dry process rotary kiln, it is necessary to corresponding exploitation has excellent performance,
Adapt to the novel refractory of new dry process rotary kiln.The operating temperature of kilneye is usually between 1100~1200 DEG C afterwards, relatively
Although decreasing in preceding kilneye temperature, as liner, then being difficult to produce using preceding kilneye castable under the conditions of this temperature
Raw sufficiently sintering, and by even more serious abrasion and washed away than preceding kilneye, in addition each start-stop kiln can make kilneye position
Change dramatically occurs for temperature, and alkaline volatile matter in kiln etc. is enriched at this position, these severe working conditions cause the position
Refractory lining used often damages, and damage is mainly manifested in peeling chip off-falling, and since alkali erosion seriously causes structure to be destroyed
Local shedding caused by and.
Kilneye castable experienced one from single selection corundum Low Cement Castable, the low cement of High-Alumina after cement kiln
Castable is extended to the process including more materials such as mullite, mullite silicon carbide.Corundum pouring material is at high cost, high
Aluminum castable thermal shock resistance is poor, and the castable inoxidizability of silicon carbide-containing matter is poor, is all difficult to reach in terms of service life
To synchronous with cement kiln liner tile.Titanium calcium aluminate was widely applied in recent years as a kind of novel material, in titanium calcium aluminate
Principal crystalline phase is calcium hexaluminate and titanium calcium aluminate, and secondary crystal phase is by the high temperature phase composition such as a small amount of Calcium dialuminate, aluminium titanates, calcium titanate, tool
Have that thermal stability is good, not aquation, the features such as thermal expansion coefficient is low, and thermal shock resistance is good, and wear-resisting property is excellent.Patent
CN107311677A, CN107285786A, CN105036774B etc. are disclosed using titanium calcium aluminate as raw material preparation fire resisting
Material, but usage mode, application field, in terms of be not able to satisfy cement rotary kiln after kilneye to refractory material
Application requirement.
