The Interfacial Behavior of Alumina-Magnesia Castables and
Focusing on alumina-magnesia castables an important lining material in ladles the interfacial behavior between the castable and different ladle slags with or without an AMF is studied in this paper. The results showed that the slag corrosion and especially the slag penetration of the alumina-magnesia castable are more severe under an AMF.

As the free-flow values increase the castables turn from ramming to self-flow. Even though self-flow castable is the preferable choice in the site the castables with flow values greater than 120 are prone to segregation a phenomenon that can be controlled if the matrix of these castables has a remarkable dilatant character.

Binders for Refractory Castables An Overview SpringerLink
· Abstract A binder for refractory castables is a bonding material that bonds a loose powdery mix retains its shape after casting and allows the cast shape to set and harden for handling and further processing. A binder also improves sintering as the castables are not compacted during shaping causing poor densification and strength. Initially plastic clay was used as a binder for castables

High Alumina Self-flow Castables with Different Binders
· Self-flow castables have been prepared by fixing the distribution coefficient q at 0 21 in the continuous particle size distribution model as proposed by Dinger-Funk. High alumina cement and silica sol were used at 4 and 6 mass- as binder and water was added during mixing till self-flowing consistency was achieved in the castable mix.
