Introduction
Ramming Mixes for EAF Bottom is made by superior compound materials, additive, and bonding agent according to the particle most compact accumulation theory and is sintered rapidly through the magnesia particle and matrix fine powder and then forms the stable mono block sinter layer, having the advantages of anti molten steel strong penetrability, anti-erosion, easy sinter, high density of accumulation, easy construction and so on.
