Product Introduction
Corundum Self-Flowing Castable for RH Vacuum Degassing Furnace is formulated with high-purity corundum as the base material and an advanced low-cement composite bonding system. The material features excellent flowability and self-leveling characteristics, enabling dense placement without vibration and ensuring superior construction efficiency.The castable exhibits low porosity, high mechanical strength, excellent resistance to vacuum spalling, and outstanding resistance to molten steel and slag penetration. It also offers exceptional thermal stability and durability under severe RH refining conditions.Designed specifically for precision applications in RH vacuum degassing furnaces, it is ideal for joint filling, repair work, surface leveling, and other areas requiring fine casting and high-quality refractory installation.
