Fused silica brick is produced from high-purity fused silica sand with high purity, few impurities and SiO2 greater than or equal to 99%. The fused silica brick supplied by our company has high strength of about 60MPa, good thermal shock stability, water cooling at 1100 ℃ for about 50 times and low apparent porosity of 14-18%. This product is a high-quality refractory brick with excellent acid atmosphere corrosion resistance, no crack and peeling, It has been well used on the top of glass furnace, coking furnace and steel rolling furnace
The product has approximately zero expansion rate, which solves the problem of poor thermal stability of ordinary silica brick, and can meet the requirements of rapid temperature rise. There is no need to dry the furnace for a long time. It can be used after laying the furnace. The product size does not change, crack or deform, and can be repaired directly without stopping the furnace
