Low price high alumina refractory clay insulation bricks 230x114x15 mm 230x114 for furnace lining

Clay brick is a special brick made of refractory clay and has good high temperature resistance.
For use in kilns, linings, fireplaces and fireboxes. These bricks are made in a similar way to regular bricks;
Except during the combustion process - refractory bricks are exposed to very high temperatures
The refractoriness of bricks is greater than 1580℃.

Choose high alumina bricks. They have a higher aluminum content than clay bricks and are used at higher temperatures. if your
Kilns require higher temperatures and longer service life, so it is recommended that you choose refractory high-alumina bricks.
