摘要
采用优质矾土、微膨胀料,引入一定量ZrO2,添加特种化学结合剂,经二次混练成型,700~800℃热处理后,制成特种高铝砖。在电炉顶上应用,其使用寿命超过烧成优质Ⅰ等高铝电炉顶砖的平均寿命。
The special high alumina brick was made from high quality Yangquan bauxite and fireproof expansion materialwith two kinds of chemicai binders,by secondary mixing and pressing and heat treatment at 700-800℃. Its mean ser-vice life is longer than that of Ⅰgrade high alumina brick for EAF roof.
