Description

A kind of three layers of composite brick and preparation method thereof
Technical field
The invention belongs to and belong to technical field of refractory materials, specifically, relate to a kind of three layers of composite brick and preparation method thereof.
Background technology
Along with the continuous appearance of manufacture of cement new technology, the manufacture of cement main process equipment, to the maximization future development, increases output, improves quality, saves energy and reduce the cost, reduces costs the key that becomes increase benefit in production management.Existing refractory brick and insulating brick are mostly single material, during use, the brick of various performances need be used in conjunction with, if on relatively fixed equipment, as tunnel furnace, down-draft kiln, be used in conjunction with and can meet the demands, but, on the equipment of some relative movement, as rotary kiln, be used in conjunction with and just be difficult to meet the demands.Some producers and research unit are studied this and tackle key problems, and released the composite brick that some heavy material and light material combine, but because lightweight part-structure intensity is too low, can't meet service requirements, and heavy part and lightweight partly easily react because of the material problem, thereby have influence on product performance and result of use, therefore do not promote on a large scale, or take the heavy brick as main.
The rotary kiln of the 10000t/d of conch group of take is example, front transitional zone is used spinel brick, clinkering zone to use magnesia chrome brick, thermal conductivity large (>=2.7W/mK) due to front transitional zone spinel brick and clinkering zone magnesia chrome brick, make the kiln cylinder body outside wall temperature higher (greatly about 380 ℃ of left and right, can reach 420 ℃ during high temperature), can make so on the one hand the kiln cylinder body heat radiation increase, thereby strengthen heat consumption of clinker, cause that the grog unit cost increases; Very easily make on the other hand the cylindrical shell expanded by heating, cause kiln middle part support roller Wa Wendu to raise, especially using the normal operation to equipment of later stage or summer to bring larger hidden danger.Cylindrical shell is the excessively heat gain damage probability of mechanical means, accelerated barrel distortion, and barrel distortion has accelerated the physical disturbance of liner, consequently falls brick, stop kiln, affects the operation factor of cement rotary kiln.
