Abstract

The brick is so constructed that the tapering surface have identical cylindrical curvature, on surface being concave and the other convex. This enables vessels of a considerable range of size to be lined satisfactorily with refractory (e.g. dolomite and/or magnesite) bricks without leaving gaping joints requiring to be specially filled later. The bricks can be made by the normal methdo of stamping, pressing, etc. A typical bricks has a foot adn which lies against the metal wall of the vessel, a head end facing the molten metal contents and the cylindrically curved side or taper surfaces. The centres of curvature of the curves lie on the dias. of the curves, which intersect on the centre plane of the disc. Any mfg. variations in the bricks are accommodated by slight rotation of the bricks round the centre of curvature of the concave face of one brick and/or the convex face of the next adjacent brick. The magnitude of the radius of curvature is a function of the thickness of the brick to be used.
