Product Details

Fused Corundum Blocks with Good price and Premium Quality

Product Description

Main mineral component of corundum brick is corundum phase, it has excellent physical property

in high temperature, resistance to chemical corrosion. It is widely used in lining of ovens of

petrochemical industry; bottom of steel rolling mill and in the second-stage converters of the

300,000t ammonia synthesis furnaces, steel notch.

Application:

Fused corundum block is mainly used in key parts of the industrial furnace that require high

abrasion and temperature resistance, such as gliding rail bricks in steel pusher metallurgical

furnaces, the tapping platform (tapping spout) style walking beam furnaces, and also as the interior

for destructors.
