Refractory Insulation Bricks/Mullite Insulation Refractory Brick /Fireclay Insulation bricks

ISO 9001:2000 Certificate Manufacturer

Zibo Shunzhou Refractory Co.,ltd is a specialized manufacturer and supplier of refractory, we can supply many kinds of refractory products, such as high alumina bricks,fireclay bricks,low porosity fireclay bricks, insulating bricks and many kinds of refractory castable,ramming mass etc.

We have exported toKorea, India, Germany, Canadaetc many countries, and they are satisfy with our products.

Insulation bricksare classified under temperature between 1300ºC and 1700ºC, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation

Refractory Insulation brickcan be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non ferrous foundries, petrochemical, ceramic, glass, cement and oil fired electric power generating plants.


Light weight and low thermal conductivity allows thinner furnace walls
Maintain stable structural strength throughout ambient to maximum service temperature
Low heat storage results in rapid cooling and heating operation
Low iron and impurities to enhance reducing atmosphere
High thermal shock resistance in preventing spalling
Non standard sizes and shapes are available upon request


Ceramic shuttle kilns
