Corundum self flowing wear-resistant castable

This product uses various artificial synthetic materials such as high-quality high alumina bauxite, corundum, and silicon carbide as the main materials according to different grades, and is matched with various additives, high-efficiency water reducing agents, flow agents, etc. This improves the material flow performance. Main features: Without increasing water consumption, relying solely on the self weight and potential energy difference of the material itself to generate flow. In a non vibrating state, it can be constructed in crevices and areas that cannot be vibrated, with excellent construction quality. It is mainly used in areas where the lining of CFB and other thermal equipment is difficult to construct and severely scoured and worn.
