Particle Distribution Design in a Self-Flow Alumina
A self-flow refractory castable (SFRC) without cement requires a matrix of fine particles and a broad size distribution of coarse particles (aggregate). The matrix ensures the rheological behaviour and performs the binding role of the absent refractory cement. The presence of the aggregate coarse particles hinders the flowability index (FI) but improves the castable mechanical strength and

Refractory castable technology for kiln mouth of cement
· In foreign countries corundum and high aluminum steel fiber reinforced refractory castable are widely used in the front kiln mouth of cement kiln and their service life can reach 2 to 8. The castable has high aluminum content and high strength. Therefore the thermal shock resistance is poor easy to crack and spalling reduce the service life.
