Light Weight Mullite Insulation Refractory Corundum mullite Brick
Product Description
1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Corundum-Mullite Refractory Bricks allow direct contact of fire, suitable ofr various atmosphere.
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely.
Product specification: standard form, normal standard, shaped and special shaped bricks.
Corundum-Mullite Refractory Bricks Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.

Features:
(1) strong resistance to erosion and scouring of molten iron and slag;
(2) good thermal shock resistance and re-burning volume
(3) strong anti-oxidation ability;
(4) easy to construct, can be quickly baked without bursting, easy to repair and dismantle;
(5) when used, no harmful gas, no sticky iron, long life. These features make them complementary and should be compatible with each other.
