High Grade Bauxite Silica Mullite Bricks For Cement Kilns , High Temperature Insulation
Description:
Silica-mullite bricks are made with raw material high grade bauxite and SiC and special sintering process. Silica-mullite bricks are characterized by high density, good performance of abrasion resistance and thermal shock resistance. It can constantly form protective layer for reducing accrection formation, long application cycle,etc.
Application:
The bricks are used for the transition zone, calcining zone, cooling zone of medium and small cement kiln.
