Corundum wear-resistant castables are wear-resistant castables made of high-quality corundum, alumina, etc. as aggregates and powders, plus binders, appropriate heat-resistant stainless steel fibers, and appropriate admixtures. High wear resistance, high compressive strength, refractoriness up to 1900°C.
High cold and hot strength, good wear resistance, thermal shock resistance, anti-stripping and good volume stability under high temperature.
