Square Mullite Silicon Carbide Bricks Rotary Kiln SiC Brick CE Approval
Rotary Kiln Silicon Carbide Bricks 2.65 G/Cm³ Bulk Density Square Size CE Approval
Silica-mullite bricks mainly designed for rotary kiln of cement industry. Silicon mullite bricks by adopting high grade bauxite and SiC as raw material and special sintering process, silica-mullite bricks are characterized by high strength, good performance of abrasion resistance and thermal shock resistance, constant forming protective layer for reducing accrection formation, long application cycle etc. Silica mulite fire bricks are used for the transition zone, calcining zone of medium and small cement kiln.
