4.Low impurities

light weight mullite brick for furnaces

 

 

Insulating mullite firebricks: It covers six temperature classes: 1300C, 1400C, 1500C, 1550C, 1600C,

includes standard brick, special-shaped brick, and refractory mortar. Our brick mainly are used in

the field of lining and backing of the hot surface of cracking heater, reborner, hot-blast furnace,

heating furnace, soaking pit, heat treatment furnaces, resistance furnace, heating device, refining

device, tunnel kiln, roller kiln, shuttle kiln, top-hat kiln and glass tank furnace in the industries of

metallurgy, petrochemical, building materials, ceramics, machinery etc.
