(1) clay refractory brick (2) high alumina refractory brick
The major category is classified as permanent layer, working lining. Specific varieties: Air permeable brick (corundum). steel ladle brick (magnesia or corundum), permanent layer castable (high alumina), reinforcing material for ladle bottom, repair material for the edge of tank and so on.
Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials
Alumina-magnesia castable is OK for small steel ladle
