company news about The main component of acid refractory materials

Acidic refractory materials with silicon oxide as the main ingredient, commonly used silica brick and clay brick. Silica brick containing more than 93% siliceous products, raw materials are used silica, silica brick scrap, with its acid-resistant slag erosion ability, load softening temperature is high, the volume does not shrink after repeated firing, and even a slight expansion; but its vulnerability to erosion of basic slag, thermal shock resistance is poor. Silica brick are mainly used for coke oven, glass melting furnaces, steel furnaces and other acidic thermal equipment. In refractory clay brick as the main raw material, thermal shock resistance, corrosion resistance to acid slag have wide application.
