Introduction
Blast furnace swing runner castables are engineered for the severe service conditions of swing runners, where molten iron and slag cause intense thermal shock, mechanical impact and chemical erosion. Formulated with dense corundum, brown fused alumina and silicon carbide as primary raw materials, incorporating special anti-oxidants and ultra-fine powder bonding, the material delivers good workability, excellent thermal shock stability and strong resistance against slag and iron penetration. It does not adhere to slag or iron and is easy to dismantle. Available in two grades—JH-TB8-X and JH-TB10-X—with alumina content of 75% and 70% respectively, and SiC+C content of 8% and 12%, to match different service conditions.
