Characteristics of aluminum-magnesium refractory castable

Aluminum-magnesium refractory castable is composed of fused magnesia, sintered magnesia, fused magnesia or sintered magnesia spinel, fused corundum, alumina powder, alumina powder and so on.

The aluminum-magnesium refractory castable has good thermal shock resistance due to the presence of aluminum-magnesium spinel or the formation of magnesia spinel in the heating process, resulting in expansion and micro-cracks, which buffering the thermal stress inside the material. At the same time, due to the large amount of aluminum-magnesium spinel in the castable, it has a strong permeability inhibiting effect on the slag.
