Application of Phosphate Brick in New Hanfa Cement Production Furnace
Aug 16,2017
Phosphate brick in the hot surface temperature can be maintained at about 600 ~ 800 ℃. Hot surface layer of the thermal expansion rate of only 0.6% to 0.7%, then the refractory brick is relatively stable, easy to burst, if exposed to 1700 ℃ above the flame, the hot surface temperature of 1500 ℃ or more, hot surface refractory brick expansion rate It may reach 1.5% (such as chrome magnesia brick), the temperature rise refractory temperature stress exceeds the strength of the brick itself, cracking peeling can not be avoided.
Phosphate brick C2S and C2F content is high, is conducive to clinker reaction and hang the kiln, but the kiln temperature changes frequently, the kiln is not easy to hang hanging, when hanging off, phosphate brick is often in the local brick Of the case, seriously affecting the life of phosphate brick.
