High quality Fused silica brick fire brick excellent thermal shock resistance for glass kiln
Fused silica brick are also called zero expansion silica bricks or thermal shock-resistant silica bricks.
Fused silica brick has the characteristics of extremely low thermal expansion coefficient, excellent resistance to rapid cooling and heating, good high-temperature structural strength, and high SiO2 content. This product can be widely used in the rapid thermal repair projects of various coke ovens. The product does not crack and flake during use, and has close to zero low thermal expansion performance, which makes the coke oven safe and reliable for long-term use after repair.
Characteristics of Fused silica brick:
1. SiO2 content is greater than 99%, excellent corrosion resistance
and acid resistance
2. Low Fe2O3 content is less than 0.1%, no pollution to products
(such as molten glass, etc.)
3. Low flux index (Al2O3+2R2O) is less than 0.3%
4. The thermal expansion rate is close to zero, so there is no need
to reserve expansion joints when repairing, which increases the
tightness of the masonry.
5. Excellent thermal stability, the product will not explode during
hot repair, and it can be directly repaired under the condition of
high temperature without stopping the furnace
6. After repair (hot repair), there will be no peeling, etc., and
it is safe and reliable for long-term use
Lower price Fused silica brick for coke oven, glass melting furnace hot repair
Advantages of Fused silica brick products:
1 The thermal shock is stable, the product will not burst during
hot repair, and the repair operation can be carried out directly
under the high temperature of the furnace;
2 The expansion rate is low, no need to reserve expansion joints
when repairing, increasing the tightness of the masonry;
3 No expansion at high temperature, good extreme cold and extreme
heat, high softening temperature under load;
4 High purity, no pollution to molten glass;
5 Cutting, grinding and drilling can be carried out according to
the requirements of the construction site;
6 No impurity pollution, no erosion and peeling phenomenon,
long-term use is safe and reliable;
7 The volume density is small, and compared with other hot repair
materials, it reduces the purchase cost.
