  • Brief Introduction

    AMR silica brick has excellent creep resistance at high temperature, low thermal expansion at high temperature, and strong resistance to load deformation at high temperature. At the temperature of the regenerator, increased insulation at the top of the regenerator will not cause deformation problems.

    Advantages: 
    • Excellent Thermal Shock Resistance
    • Volume Stability
    • High Strength
    • Low Apparent Porosity at Elevated Temperatures 
    Applications: It has been used extensively for coke oven hot repairs, glass tank crown as well as regenerator crown and separate wall repairs.
