Products Overview
Our Burner block is a high-performance refractory product engineered for industrial furnace burner lining service. According to the structure and service condition of burner, we successfully developed series of corundum-mullite based and mullite based burner blocks. These products have good properties such as high strength, good thermal resistance, and excellent performance for industrial furnace burner lining service.
The Burner block product family is offered in two engineering-proven SZ chemistry grades. The CH-SZ65 grade features Al2O3 content minimum 65% for general industrial furnace burner lining service, with Bulk Density minimum 2.45 g/cm3, Cold Crushing Strength minimum 40 MPa after 110 °C drying for 24 hours and minimum 60 MPa after 1500 °C firing for 3 hours, and Permanent Linear Change maximum 0.5 percent after 1500 °C firing for 3 hours. The CH-SZ75 grade features Al2O3 content minimum 75% for higher-demand industrial furnace burner lining service, with Bulk Density minimum 2.6 g/cm3, Cold Crushing Strength minimum 50 MPa after 110 °C drying for 24 hours and minimum 65 MPa after 1500 °C firing for 3 hours, and Permanent Linear Change maximum 0.5 percent after 1500 °C firing for 3 hours.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Burner block grade is engineered to ASTM, GB/T, and ISO refractory standards.
