Refractory Silica Brick
Brief description
1. High refractoriness under load.
2...High heat conductivity
3. Good thermal shock resistance
Typical Application
Silica Brickis mainly used for building of coke oven, also used in a variety of glass, ceramics, carbon calciner, the furnaces of refractory brick vault and other bearing parts, also used for high temperature bearing parts of the hot blast stove.
Advantage of Silica brick
Silica brick, refers to the refractory brick containing SiO2 over 93 %, the main varieties of refractory brick is acid. It is mainly used for building of coke oven, also used in a variety of glass, ceramics, carbon calciner, the furnaces of refractory brick vault and other bearing parts, also used in bearing parts of the high temperature of hot blast stove, but should not be used in below 600 º C and temperature fluctuations of thermal equipment.
