Rotary kiln introduces with the action of brick of light qualitative wear-resisting and energy-saving effect

March 15, 2024Nov 25, 2024


Rotary kiln pledges with the action of brick of light qualitative wear-resisting wear-resisting brick is used at cement to answer gently be like,pass kiln at the back of kiln 10~15m, use at 56.2~73.2m place commonly to the kiln of 5000t class cement of 4.8*74m, use at the positional office of 45.9~59.1m commonly to the kiln of 2500t class cement of 4.0~60m. Brick of light qualitative wear-resisting has inferior coefficient of thermal conductivity and temperature of inferior bate of bulk density loading and compression intensity to also be reduced somewhat, but the use that does not affect brick of light qualitative wear-resisting, because be in this one interval, the thermic load of stock is lesser, of solid stock erode and wear away lighter also, because this is on fireproof material configuration, main consideration is comfortable fight alkaline erode ability to be able to pass the actual application of brick of light qualitative wear-resisting in rotary kiln, had better heat preservation effect, in appearance of kiln cylindrical shell wind speed is 2.5m/s; The average temperature outdoor falls for the circumstance of 25, the cylindrical shell temperature that uses brick of light qualitative wear-resisting is 247 ℃ , use silicon not temperature of cylindrical shell surface is 289 ℃ . A day produces line of 5000t class grog to reduce nearly 42 ℃ through using temperature of cylindrical shell of brick of light qualitative wear-resisting, annual but 390t of managing mark coal. The surface of system of kiln of energy-saving effect cement of brick of light qualitative wear-resisting comes loose to heat up a loss hotly to include intake air heater, rotary kiln and cooling plane. Among them the 50% above that the heat loss due to radiation of rotary kiln occupies total heat loss due to radiation, the new-style and energy-saving brick that because this is developed,is used at rotary kiln with development is energy-saving to cement industry particularly important. New-style and energy-saving fireproof material is main with light qualitative aggregate and the small qualitative dose that make hole makes brick of light qualitative wear-resisting for raw material, it passes the density that reduces material and the coefficient of thermal conductivity that raise the porosity of material to reduce fireproof material, achieve the goal with energy-saving heat preservation thereby. Brick of this kind of light qualitative wear-resisting basically is used at the cent ungird of rotary kiln. Brick of light qualitative wear-resisting is used at cement to answer be like,pass kiln at the back of kiln 10-15m, use at 56.2m-73.2m place commonly to the act vigorously of cement of 5000 tons of class of 4.8m × 74m, use at the positional office of 45.9m-59.1m commonly to the kiln of cement of 2500 tons of class of 4.0mX60m. Brick of light qualitative wear-resisting has inferior coefficient of thermal conductivity and inferior bulk density. Loading bate temperature and compression intensity also are reduced somewhat, but the use that does not affect brick of light qualitative wear-resisting, because be in this one interval, the thermic load of stock is lesser, of solid stock erode and wear away lighter also, because this is on fireproof material configuration, main consideration is comfortable fight alkaline erode ability can. Pass the actual application of brick of light qualitative wear-resisting in rotary kiln, had better heat preservation effect, in kiln the circumstance that for 2.5m/s; the average temperature outdoor is 25 ℃ plays simplified and outside wind speed, the simplified temperature that uses brick of light qualitative wear-resisting is 247 ℃ , the simplified surface temperature of brick of use silicon beanstalk is 289 ℃ , a day produces limited company of rich in relief southern cement line of grog of 5000 tons of class pledges through using simplified temperature reduces wear-resisting brick gently nearly 42 degrees, everyday managing quantity of heat is 9010904.7 kilocalorie, annual but managing mark coal 390 tons. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
