High Quality Silica Brick - China

price: contact company for price

Silica brick is a kind of acid refractory mainly made from tridymite,

cristobalite and a small amount of residual quartz as well as glass

phase. The raw material is natural silica sand whose SiO2 content should

be more than 96% . The higher SiO2 content in silica sand, the higher

temperature silica bricks resist. Silica bricks are used in the roof and

superstructure of glass melting tanks as well as for hot repairs.

â–ºOur silica brick advantages

- - Adopts high quality silica and advanced technology, our silica bricks enjoy the advantages of high purity, long service life, good thermal conductivity, high refractoriness under load, and good creep resistance.

- - In addition, it has accurate size tolerance, pure color and luster appearance.

- - Because of the good thermal shock resistance of silica brick, it is mainly used in the continuous operating furnace.

- - Supporting the use of other high quality refractories, our silica brick can extent the service life of float glass furnace to 8 years and double the service life of bottle glass furnace.

â–º Applications

The silica brick can be widely used in coke oven, hot blast furnace, glass furnace and carbon furnace. In glass industry, it is mainly employed to build the doghouse crown, suspended wall of channel, top crown and inlet sealing. In detail, silica bricks plays the following role in different fields:

- - being the partition walls in coke oven carbonization and burning chamber;

- - metallurgy industry: used as refractories for steel making open hearth regenerator, slag pocket, soaking pit;

- - arch crown and other weight bearing areas in ceramic kilns, hot blast furnace and acid open hearth;

- - worked as building checker chamber, chute, combustion chamber, coking chamber and furnace arch in glass melting furnaces.

â–º Specifications

1. Higher SiO2 content of more than 96% , with true density of 2.34g/ cm3, thus it has good performance in corrosion of acid slag.

2. Excellent resistance in high temperature. The melting temperature under load is 1620- 1670℃. Durable, with no deformation under high temperature.

3. Good thermal shock resistance, High heat conductivity.

4. At 1450℃, there is 1.5- 2.2% overall expansion which makes the joint- cutting dovetailed, thus silica bricks have good air tightness and strong structure.
