A substantially planar slab has two opposite edges castellated in such fashion that two such slabs may be interengaged with the slabs in the same plane with the castellations of one edge of one slab interfitting the castellations on the other edge of the other slab. The sides of the castellations are inclined in a direction not normal to the plane of a major face of the slab. Such slabs are useful for lining containers for molten metal, and when forming such a lining all joint faces of the interengaging castellations not lying in vertical planes can be arranged to slope downwardly away from the interior of the molten metal container. The thickness of the slabs, the angle of the castellations, the period of the castellations and the inclination of the slabs can be so chosen relative to the angle of repose of a loose fill of refractory material under the slabs that the loose fill particulate refractory material does not penetrate the joints between adjacent slabs.
A container for molten metal having a floor and sidewalls and having an inner wall lining made up of a plurality of slabs of refractory heat insulating material having generally vertically generally planar major faces, at least some of the slabs having two opposite edges castellated, said castellated edges including a plurality of teeth with slots defined between the teeth, said slots extending from one major slab face to the other, with interengaging castellation teeth forming the joints between the slabs, all joint faces of the castellation teeth not lying in vertical planes slope downwardly away from the interior of the molten metal container.
A container for molten metal having a floor and sidewalls and having an inner wall lining made up of a plurality of slabs of refractory heat insulating material, with loose fill of refractory material between the container sidewalls and the inner wall lining, at least some of the slabs having two opposite edges castellated, said castellated edges including a plurality of teeth with slots defined between the teeth, said slots extending from one major slab face to the other, with interengaging castellation teeth forming the joints between the slabs, wherein the thickness of the slabs, the angle of the castellation teeth with respect to the vertical and horizontal, the dimensions of the castellation slots, and the inclination of the slabs are so chosen relative to the angle of repose of the loose fill refractory material behind them that the loose fill particulate refractory material does not penetrate the joints.
