The coal-fired power plant coal pulverizing, ash, dust, coal conveying system, in the operation of the equipment due to driving by the medium of friction, collision and impact erosion, such as identity, the influence of system easy to leak, cause pollution. It is the power plant to improve the production of peace and civilization, to create the first class of the hard work. To this end, the power plants responded to the differences in the treatment of leakage; Among them, the wear-resisting ceramic lining plate is the ideal treatment leakage material, its wear resistance, practicability, economy is superior to other wear-resisting material.
1. Main performance characteristics of wear-resistant ceramic lining:
Wear resistant ceramic lining plateis 3 oxidation 2 aluminium as the main raw material, with rare metal oxide as the flux, through 1700 ℃ high temperature sintering of special alumina ceramic, subdivided with special rubber and high strength organic or inorganic binder combination product. It has the following main properties and features:
(1) hardness of the night, its rockwell hardness is 85-90.
(2) good wear resistance and long service life, its wear resistance is equal to 266 times of manganese steel and 171.5 times of high chromium cast iron.
(3) it has a wide range of use, and it has the adhesive type lining board which is suitable for direct feeding of low temperature; It has the impact type lining of the material impact. There is a straight adhesive lining for wind conveying powder with high temperature. It has a type of rapid tubular composite lining. There is a viscose ceramic fan blade with high speed running.
