Feature: Long Time Materials
Type: Refractory Material
Zero expansion silica brick
Main feature:
1. SiO2 content is more than 99%, excellent in corrosion resistance and acid resistance
2. Low Fe2O3 content is less than 0.1%, no pollution to products (such as glass, etc.)
3. Low flux index (Al2O3+2R2O) is less than 0.3%
4. The thermal expansion rate is close to zero, and there is no need to reserve expansion joints during repair to increase the tightness of the masonry.
5. Excellent thermal stability, the product will not burst during hot repair, and can be directly repaired without stopping the furnace at high temperature.
6. After repairing (hot repair), no peeling or the like will occur, and long-term use is safe and reliable.
Silica bricks Application
Widely used in high temperature thermal equipment such as glass melting furnace, coke oven and hot air furnace. Especially high temperature thermal equipment can be repaired without stopping the fire.
