Wear Resistant Sidewall Block Alumina Industrial Kiln Refractory Materials
Quick Detail:
1, Low permanent linear change on reheating
2, Good Thermal Shock Stability
3, High dense structure
Description:
Wear-Resistance bricks are made of raw materials such as high-grade
bauxite and Australia imported zircon sand, which are melted and
founded in high temperature electric furnace. It is mainly used in
areas that require high abrasion and temperature resistance, such
as gliding rail bricks in steel pusher metallurgical furnaces, the
tapping platform (tapping spout) for tapping platform (tapping
spout) style walking beam furnaces, and also as the interior for
destructors.
Applications:
1, Sulfuric cracking furnace
2, Fibrous glass furnance
