High RUL Low Creep Rate quartzite Checker Silica Fire Brick
Introduction:
Low Creep Rate Silica Checker Brick is fired in high temperature with quartzite as its raw material and adding a little mineralizer. Low Creep Rate Silica Checker Brick' mineral composition includes tridymite, ashlar and vitric formed in high temperature.
There are 50~80% quartzose content, 10~30% cristobalite and 5~15% quartz and glass phase content in the better sintering Low Creep Rate Silica Checker Brick. Fire brick and refractory brick.
Low Creep Rate Silica Checker Brick is mainly made of top class silica, via shaping and burning under the high temperature,
possesses high temperature resistant,high strength and low impurities,etc.
Low Creep Rate Silica Checker Brick is mainly used for blast furnaces and hot blast stove.
The most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.
Lighter weight,Low thermal conductivity,low impurities,high insulating properties,high CCS and exact tolerance.
Light weight silica brick:
1) Silicon oxide is above 94%.
2) Good acid erosion resistance.
3) High softening point
Package:
Low Creep Rate Silica Checker Brick are packed on wooden pallet and then polyethylene film is placed over it,finally the package is tied up with steel strips or as your request
