In the steel industry there is also a tendency to use refractory castables with high alumina and spinel contents. Both Al 2 O 3 -spinel and Al 2 O 3 -MgO refractories are widely used as a steel ladle lining below the slag line although in recent years the Al 2 O 3 -MgO refractories have been replaced by Al 2 O 3 -spinel due to their superior
