Under its self-weight, it could be degassed and leveled without vibration so as to become compact. The product has an appropriate setting and hardening time. It saves labor and effort. Its handling easy and convenient and it has high strength, long service life, high-temperature resistance, good thermal shock stability, corrosion resistance and erosion resistance. Corundum self-flow castable is divided into low cement, ultra-low cement and non-cement castables. This product is widely applied. It is suitable for filling the ladle bottoms, around the well blocks, and the EAF roof.
