Abstract
Method and geometrical arrangement of refractories within a high temperature vessel. A protuberance near the periphery of the vessel opening is formed on an inner surface and a ring of trapezoidally-shaped refractory brick is positioned such that a sloping surface of each of the trapezoidally-shaped brick is preferably initially in contact with an adjacent surface of the protuberance. When the interior of the vessel is heated and the brick expand, they tend to ride upwardly, with the sloping surfaces urging the brick inwardly thereby increasing lateral friction therebetween, thereby holding them in place and preventing them from moving even when the vessel is tilted or turned upside down.
