Product Description

High aluminum poly light insulating brick

Characters of High aluminum poly light insulating brick

High aluminum poly light insulating refractory bricks use special grade bauxite as main raw material and poly light ball sintered form, and with high strength, small firing linear change and low thermal conductivity. It can be used at temperature 1400-1500 ºC and can direct contact with the flame.
 
Applications of High aluminum poly light insulating brick

Suitable for the various types of high-temperature furnace, pyrolysis furnace, hot stove, ceramic kiln, electric porcelain drawer and all kinds of resistance furnace lining. Widely used in metallurgy, electric power, petroleum, chemical industry, ceramics and other industry furnaces.
