iron ditch castables using corundum as the main raw material, appropriate with silicon carbide, carbonaceous materials, clay, high alumina cement, ultrafine powder, admixture and made. In order to ensure that the product has the characteristics of large density, high strength, resistance to erosion, erosion resistance, non-sticky slag, easy construction, large amount of iron and long life, Dry, do not burst and other characteristics, greatly reducing the repair time, to avoid the turn of the trench due to the impact of iron production.
