High temperature refractory alumina castable for hot blast furnace
High temperature refractory alumina castable for hot blast furnace
Details of our refractory castable material
Refractory castable is one of the unshaped refractory materials.
1.It is made of refractory aggregate, refractory powder, binders and other additives.
2.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.
3.It is one of the new type refractory material of don't need calcination.
Advantages feature of refractory castable material
1.Easy to construction
2.High mechanical strength
3.High density, low porosity
4.Good thermal shock resistance
5.High refractoriness, High refractoriness under load
6.Good abrasion resistant, Good resistance to flake performance
