wearable refractory castable

refractory castable Description Wearable corundum refractory castable uses aggregate of fused white corundum, compact fused corundum and brown corundum or vice white corundum, mixed with superfine powder, high-efficient water reducing agent. It has the features of good fluidity and being convenient for construction. It is an ideal high temp and wear proof lining material of some thermal equipment, such as circulation sulfuration bed boiler and rotary kiln.refractory castable Features ·High strength at both high and low temp ·Excellent wear resistance ·Thermal shock resistance ·Anti-peeling-off ·Stable bulk at high temperature ·Long service liferefractory castable Application Coal burners, circulation sulfuration bed boilers, linings of catalytic cracking, sulphur relovery devices mouth of rotary kiln and mouth of cooling machine, etc. Properties ⁄Brand HC-3.1 HC-3 HC-2.9 Chemical Composition % Al2 O3 95 92 85 SiO2 0.5 0.6 10 CaO 2.5 2.5 3.0 Bulk Density g⁄cm3 110°C×24h 3.1 3.0 2.9 1450°C×4h 3.0 2.9 2.8 Compressive Strength Mpa 110°C×24h 115 110 95 1100°C×4h 110 105 86 1450°C×4h 105 100 80 Modulus of Rupture Mpa 1100°C×4h 8 10 11 1450°C×4h 12 13 14 Heating Linear Change % 1450°C×4h ±0.3 ±0.3 ±0.4 Wear Resistance cm3 4.5 5.0 5.0
