The main component of acid Refractory is silica, commonly used in Silica brick and clay brick. Silica brick is more than 94% silicon oxide products, using raw materials such as Silica, waste silica brick, its acid slag corrosion resistance, high softening temperature, repeated calcination volume does not shrink, even a little expansion; But it is easy to be corroded by alkaline slag and has poor thermal shock resistance. Silica brick is mainly used in coke oven, glass furnace, acid steel furnace and other thermal equipment. The clay brick is mainly made of fireclay and contains 30% ~ 46% alumina. It is a weak acid Refractory with good thermal vibration resistance and corrosion resistance to acid slag.
