Product Details
Performance & Advantages:
High-temperature volume stability;
Excellent thermal shock resistance;
Good wear resistance;
Resistance to chemical erosion.
Applications:
High-alumina refractory bricks are mainly used in key areas of lime kilns that require high temperature resistance, corrosion resistance, and wear resistance. These areas have extremely high requirements for the performance of the materials.Such as rotary kiln transition zone, preheater, and other thermal equipment requiring thermal shock resistance.
