描述

粘土质拱脚砖产品介绍

粘土质拱脚砖的造型由一个直角三角形和两个互为余角的倾斜角组成,Al ₂O ₃含量一般在30%~40%,Fe₂O₃含量小于2.0~2.5%。粘土质拱脚砖属于弱酸性耐火制品,能抵抗酸性熔渣和酸性气体的侵蚀。

粘土砖质拱脚砖用来高温窑炉拱形窑顶使用,是拱形窑顶的重要组成部分,它对窑炉的寿命有着决定性的影响。因此拱角需要能承受高温作用,重量轻,保温性能好,它的结构应严密不漏气,并有利于窑内气流的合理分布。

粘土质拱脚砖具有耐高温、热膨胀系数稳定、荷软温度高、耐酸性腐蚀等特性,广泛应用于工业窑炉拱形窑顶的建造中,例如隧道窑拱顶中一般使用倾斜角为45°或60°的粘土质拱脚砖。
