Low Price High Alumina Refractory Clay Insulation Brick 230x114x15mm 230x114 For Furnace Lining

Clay brick is a special brick made of refractory clay, which has good high temperature resistance.
For kilns, lining furnaces, fireplaces and fireboxes. These bricks are manufactured in a similar way to regular bricks,
Except during combustion - refractory bricks are exposed to very high temperatures
The refractoriness of the brick is greater than 1580°C.

In addition, we also have SK36, SK37, SK38, SK40 refractories
Choose high alumina bricks. They have a higher aluminum content than clay bricks and can be used at higher temperatures. if your
Kilns require higher temperature and longer service life, it is recommended that you choose refractory high alumina bricks.
