High Alumina Refractory Castable for blast furnace
Refractory castable,High alumina refractory castable,Alumina refractory castable
introduction :
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,Has 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. In general the use of the site casting, vibration or tamping pouring molding method, a preform can also be made pre-formed components.
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
