KRNC high alumina balcined bauxite 55% 70% 80% 90% Al2O3 bauxite ore refractory aggregate
Introduction
High alumina high strehgth refractory castable is one of the unshaped refractory materials. It is made of refractory aggregate, refractory powder, binders and other additives. It is loose, no fixed shape, high liquidity, casting and vibration molding, can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don't need calcination.
Features
1. High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
5. Good resistance to flake performance.
6. Good thermal shock stability.
7. Scouring resistance
8. Good hot strength.
