Zero Expanded Fused Silica Brick for Glass Furnace Hot repaire do not need to stop the Furnace
Zero Expanded Fused Silica Brick for Glass Furnace Hot repaire do not need to stop the Furnace
The zero-expanded fused silica brick is made of high-purity fused silica. By adding a small amount of admixture and adopting a specific firing system, the zero-expanded fused silica brick realizes the dense sintering of the product and controls the formation and development of the crystalline phase of the amorphous fused silica. Zero Expanded fused silica brick products have high SiO2 content and are all in amorphous state, and their thermal expansion rate is close to zero. Zero expanded fused silica brick has excellent thermal shock stability, which can well meet the thermal repair of glass furnaces to refractory materials. Performance requirements.
Zero Expanded Fused Silica Brick Specifications:
1.Zero Expanded Fused Silica Brick SiO2 content is more than 99%, excellent in corrosion resistance and acid resistance
2. Zero Expanded Fused Silica Brick Fe2O3 content is less than 0.1%, no pollution to products (such as glass, etc.)
3. Zero Expanded Fused Silica Brick flux index (Al2O3+2R2O) is less than 0.3%
4. Zero Expanded Fused Silica Brick 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, Zero Expanded Fused Silica Brick 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.
