Product introduction of wear resistant castable
Corundum wear-resistant castables are refractory castables prepared with corundum as aggregate and powder plus some binders, and the aluminum content of corundum series castables is relatively high, so the use effect is also relatively good.
Features of wear resistant castable
- Good thermal strength
- High strength and wear resistance
- Good anti-stripping performance
- High density and low porosity
- Good thermal shock stability
- Good slag resistance and corrosion resistance
