摘要
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。
Tbe good quality non-roasting top brick with sensible porosity of 17%, volume density of 2. 88g/cm,load test temperture 1560℃(defomation 3%)and resistance to quick heat and quick cold >30 times has be developed The main material of this brick is good quality alumina grog,added in part industrial aluminium oxide powder for strengthening matrix phase,introduced into reasonable quantity of sillimanite and compound M and used high effective complex bond.This paper also analyzes the mechanism of increasing resistance to peeling。 The averge service life of this brick is 145 times and the maximum can be up to 210 times,which is used in 30t electric furnace、The service life is increased by a factor of 2 times compared with original used brick.
