Products Overview
Our Clay insulating brick is a high-performance refractory product engineered for masonry industrial furnaces and other thermal furnaces and equipment insulation and furnace lining service. The clay heat-insulating bricks made by advanced and unique technology have the characteristics of high compressive strength and good thermal shock resistance. After use, the hot melt amount of the furnace wall can be reduced and the thermal efficiency of the furnace can be improved. Used in the insulation of masonry industrial furnaces and other thermal furnaces and other thermal equipment and furnace lining.
The Clay insulating brick product family is offered in four engineering-proven NG chemistry grades. The NG-0.5 grade features Bulk Density minimum 0.5 g/cm3 for general industrial furnace insulation service, with Cold Crushing Strength minimum 1.5 MPa, Reheating Line Change maximum 2.5 percent after 1250 °C drying for 3 hours, Thermal Conductivity maximum 0.18 W/m.k at average 350 °C, Load Softening Temperature minimum 1160 °C at 0.1 MPa, Fe2O3 content maximum 2.5 percent, and Maximum Service Temperature 1150 °C.
