Fused Silica Brick

Application of fused silica brick
Model Number: Fused silica-99
Certification: ISO9001
Minimum Order Quantity: 1 TONS



Fused silica bricks are also called zero-expansion silica bricks or thermal shock-resistant silica bricks.

Fused silica bricks have good thermal shock stability, soft weight temperature, different physical and chemical indicators, and close to zero expansion rate. It is mainly used for maintenance of glass kiln and coke oven in hot state. It does not expand at high temperature and has good rapid cooling and rapid heating. The chemical properties of zero-expansion silica bricks are good and stable at high temperature; after repairing the glass melting furnace, there is no impurity pollution, no erosion and peeling phenomenon, and it is reliable for long-term use. Compared with traditional hot-repair products, zero-expansion silica bricks are easy to use, reduce the labor intensity of operators in harsh environments, and can be repaired during the operation of the glass melting furnace, saving energy and improving economic benefits

Product features of fused silica bricks

1. Good thermal shock stability; after more than 30 cycles of water cooling at 1100°C, the product has no dimensional change, no cracking, no deformation, and can be directly repaired at high temperature without stopping the furnace.

2. The thermal expansion rate is close to zero.

3. The softening temperature under load is high, reaching 1680°C. The chemical properties are good and stable at high temperatures. After the glass kiln is repaired, there is no impurity pollution, no erosion and peeling, and it is reliable for long-term use.

Production Equipment

Production capacity: Our factory actively response to government environmental protection policy, we designed and built the fully automatic controlled high temperature gas tunnel kiln (1700℃), and got capacity of annual output 70,000 tons of high quality refractory products.
