Kiln Mouth Castable
Al₂O₃+SiC: ≥85
CaO:≤2.2
- Commodity name： Kiln Mouth Castable
Description
Introduction
The outlet of cement rotary kiln is subject to attack of cool air, hot clinker and extremely high stress, leading to common pre-wear of lining material with cracking, spalling and bursting. The optimization of alumina, SiC and calcium aluminate (CA) cement additions makes the castable have high thermal shock resistance, high strength and high flexibility to prolong their utilization.
