LQ White Corundum Castable
LQ White Corundum Castable


Corundum(White fused alumina) taking high-quality aluminum oxide powder as raw material is refined and crystallized after fused. It is high purity, good self-sharpening, acid corrosion, high temperature, thermal performance and stability which is slightly higher than corundum hardness, toughness slightly lower high purity, good self-sharpening, strong grinding capacity, low heat, high efficiency, acid corrosion, high temperature thermal stability. It is also can be Made for mould which is grinding high carbon steel, high speed steel and stainless steel and some fine-grained abrasives, and also can be used for precision casting and advanced refractories.
Advantages:
High purity, good self-sharpening,
Acid corrosion, high temperature,
thermal performance and stability
high purity, good self-sharpening,
strong grinding ability,
efficient high acid corrosion,
high temperature thermal stability.
