Yellow CCS 40Mpa 1650C Alumina Silicate Refractory Brick
Yellow CCS 40Mpa 1650C Alumina Silicate Refractory Brick
Introduction:
Yellow Silica Dense Brick is fired in high temperature with quartzite as its raw material and adding a little mineralizer. Yellow Silica Dense 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 Yellow Silica Dense Brick. Fire brick and refractory brick.
-
Yellow Silica Dense 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. -
Yellow Silica Dense 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.
