SILICA BRICK S-95A for Hot-Blast Stoves
CMAX Silica bricks are made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.
Application
CMAX Silica bricks are commonly applied in coke oven, hot blast stoves, glass furnace etc.
Features
High refractoriness under load
High mechanical strength
Excellent thermal shock resistance
Corrosion resistance.
CMAX Silica bricks are made from high quality quartz tail sand, lime and minaralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.
