所述的复合凝胶粉为锆凝胶粉和铝凝胶粉的复合粉，其重量比为1:2，所述的均化矾土的氧化铝含量＞85%。。
所述改性镁钙砂是指镁钙砂用H2C2O4进行浸渍和碳酸化处理，使镁钙砂表面形成抗水化的包覆膜。
所述烧结微孔铝尖晶石为氧化铝含量≥78％，闭口微孔的孔径≤5微米，闭口微孔占总气孔的80%以上。
所述珍珠陶土的铝含量≥30%。
所述改性纯铝酸钙水泥为水泥生产过程中加入了5%的铝尖晶石，3%碳酸锆再经高温烧结制造出来的特性水泥，改性铝酸钙水泥的铝含量≥75%。
本发明的有益效果是：
本发明可以减少铁水内硫磷等元素对铁水工作层内衬的侵蚀破坏反应，减少铁水包工作层的粘渣，大幅增加了铁水包工作层的抗热震性能，有效提高了整体浇注铁水包工作层的使用寿命，比常规同类型的铁水包工作层寿命提高30%以上。
