ULTRA-FLO 51 is designed as a lining material for ladles and can also be used for lining copper-alloy ladles and tundishes. It exhibits excellent volumetric stability and thermal insulation performance, making it ideally suited for use as the lining in pouring ladles where minimal temperature drop during service and superior heat retention are required. Made primarily from high-purity aluminum-silicon-based materials, it is a low-cement castable that offers outstanding workability, high strength, and exceptional resistance to slag and molten iron erosion.
