Corundum Castable

Corundum castable also has different grades and is also a low-cement castable made using micro-powder technology.

Corundum castable is a castable with an aluminum content of more than 90%.

Corundum castable is a high grade castable in the refractory castable series. Corundum castable also has different grades and is also a low-cement castable made using micro-powder technology.

  1. Because corundum castable has good high temperature resistance
  2. Wear resistance, erosion resistance, good air tightness, rapid setting and high early strength.

The application scope of corundum castables is mainly in high temperature areas, erosion and severe erosion areas. Such as the cement rotary kiln mouths, steel industry and the power industry boiler furnace.

Corundum castables can be made into composite types by adding different materials, such as chrome corundum castables, composite brown corundum castables, white corundum castables, and sintered corundum castables.
