以优质高铝矾土熟料为主要原料，加入部分工业氧化铝粉强化基质相，引入适量硅线石和化合物Ｍ，采用高效复合结合剂，试制出了显气孔率１７％，体积密度２．８８ｇ／ｃｍ￣３，荷重软化温度（变形３％）１５６０℃，耐急冷急热性＞３０次的优质不烧电炉顶砖。并浅析了耐剥落性提高的机理。制品经在某厂３０ｔ电炉上使用，平均寿命１４５次，最高达到２１０次。 High-quality bauxite clinker as the main raw material, adding part of the industrial alumina powder to strengthen the matrix phase, the introduction of the appropriate amount of sillimanite and compound M, the use of high-performance composite binder, trial developed a porosity of 17%, the bulk density of 2.88g / Cm ~ 3, the load softening temperature (3% deformation) 1560 ℃, quenching and tempering> 30 times the high quality non-burning furnace top brick. The mechanism of improving the spalling resistance was also analyzed. Products used in a factory 30t electric furnace, the average life expectancy of 145 times, up to 210 times.
