Mullite insulating brick description

The mullite insulating brick is an insulating refractory product made of mullite as a main raw material. The mullite insulating brick is resistant to high temperature, high strength, low thermal conductivity, and can directly contact the flame. It is suitable for the lining of various industrial furnaces.The refractoriness of mullite insulating bricks can reach above 1790 °C. Load softening start temperature 1600-1700 ° C, normal temperature compressive strength 70-260MPa, good thermal shock resistance, high strength, low temperature creep rate, low expansion coefficient, low thermal coefficient, acid slag corrosion. The utility model can greatly reduce the weight of the high temperature furnace body, reform the structure, save materials, save energy and improve production efficiency.

Mullite insulating brick application

Mainly used for high temperature air temperature metallurgical hot blast furnace above 1400 °C, torpedo car affected by molten iron impact, slag line, roof of steelmaking electric arc furnace, material channel of glass melting furnace, regenerator chamber arch, superstructure, ceramic sintering kiln, Ceramic roller kiln, tunnel kiln, electric porcelain drawer kiln, oil cracking system dead corner lining, glass kiln and various electric furnace lining, clarification pool wall, cement, lime rotary kiln lining, etc., can directly contact the flame.
