A Series Insulating Bricks

According to JIS industry standard. we produce WAM A.B.C series insulating bricks, mainly supply to East Asia and Southeast Asia countries. WAM bricks have low iron content, low thermal conductivity, low thermal capacity, low impurities, low linear change and excellent characteristics for erosion resifttance atmosphere, also have high strength, good thermal shock resistance, advanced features of dimensional accuracy. The products are widely used in industruil Annealing furnace, Carbonization furnace, Tempering furnace, Cracking furnace, Roller kiln, Tunnel kiln, etc.

Advantages

Low Thermal Conductivity

More porosity brings excellent insulation effect,energy saving.

High Crushing Strength

High crushing strength under thermal state, volume stability.

Low Heat Storage

Little thermal storage when absorb more heat, energy saving effect is obvious.

High Purity

Low content of iron, alkaline and metal impurities.

Accurate Dimension

Precise brick size by machining, cutting and grinding special shapes, expediting bricklaying.

Customized

No longer are there design limitations caused by traditional standard brick shapes and sizes. The nominal cost of customized sizes is more than offset by the elimination of many mortar joints and significant labor savings.
