Product Details

Refractory Fused Cast AZS Fire Bricks for boiler

Refractory Bricks are the most widely used materials both in glass contact and superstructure of glass melting furnaces.

The products have passed the ISO international certified,are made of high pure material, fired at high temperature by advanced technology,

Advantages of Refractory Bricks

high strength,high compression resistance,

good thermal shock resistance,

good perfomance in high temperature,

good thermal conductivity,

good erosion resistance and so on.Widely be used for linings of furnace in industries.
