BG-96A Glass furnace use silicon brick
1. Glass furnace use silicon brick Introduction :
Silica bricks are mainly acidic refractories composed of lin quartz, cristobalite and a small amount of residual quartz and glass phases. Its silica content accounts for more than 96%, it has anti-acid slag erosion performance, high temperature and high temperature, long-term use at high temperature without deformation, and can extend the service life of 7-8 years.

3. Application
It is mainly used in the coke ovens, blast furnaces and glass kiln of metallurgy, building materials, light industry, chemical industry, electronics and other industries, such as large scorpion, chest wall, regenerator roof and target wall.
Mainly used for the carbonization chamber of the coke oven and the partition wall of the combustion chamber.
The regenerator and sediment chamber of the steelmaking open hearth, the refractory of the soaking furnace, the refractory of the glass melting furnace and the firing kiln of the ceramics, etc., the vaults and other load-bearing parts of the furnace, used for the high-temperature load-bearing parts of the hot blast stove and the acid flat furnace top.
4. Packing
High-quality silicon brick packaging: steel frame packaging, wooden box packaging, wooden pallet packaging, etc. (made according to customer requirements)
