Corundum Refractory Catable Material Rafractory Castable Refractory Ramming Material
Corundum wear-resistance castable is made from special grade corundum, alumina, etc. as the aggregate and segregation, added with bond, moderate heat resistance stainless steel fibre and some additive. It is of good anti-stripping and shock resistance, is the ideal wear-resistance material for circulating fluidized bedboiler.
