Silica bricks are made from silica≥ 96%, adding mineralizers and binders, and going through processes such as mixing, molding, drying, and sintering.
characteristic:
Silica brick is an acid refractory material with strong resistance to acid or erosion.
The high soft temperature is an excellent characteristic of silica brick, generally 1640~1680℃.
Usage:
Silica bricks are mainly used to build the carbonization chamber, combustion chamber and partition walls of coke ovens (about 73% of the refractory materials used in a coke oven are silica bricks), the kiln roof, pool walls, and high temperature load-bearing parts of hot blast stoves. , carbon roasting furnace and other thermal kilns
