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

Silica refractory brick is mainly used for the partition wall of the carbonization chamber and the combustion chamber of the coke oven, the regenerator and the slag chamber of the steel-making open hearth, the soaking furnace, the refractory material of the glass melting furnace and the firing kiln of the ceramics, etc. The dome of the kiln and others load bearing part. It is also used for high temperature load-bearing parts of hot blast stoves and acid open hearth furnace tops.
