Patent

CA 2088309

The present invention pertains to a system of sized bricks for lining spherical bottoms, especially of metallurgical vessels, wherein the individual sized bricks are defined by six, essentially flat surfaces, namely, the fire-side surface, the cold-side surface, the two lateral surfaces, as well as the inner and outer surfaces, and the said sized bricks are intended for arrangement in concentric rings (1, 2, 3, ..., A, B, C, ...), wherein the sized bricks within each of these rings (1, 2, 3, ..., A, B, C, ...) join each other with their lateral surfaces, and wherein the outer surfaces of the sized bricks of one ring (1, 2, 3, ..., A, B, C, ...) border on the inner surfaces of the sized bricks of the next ring (1, 2, 3, ..., A, B, C, ...). A simple modular design is obtained by providing two basic sizes of sized bricks, wherein the sized bricks of the first basic size have a defined distance (r) between the imaginary intersection line of the inner surface with the outer surface and the fire-side surface, and wherein the sized bricks of the second basic size have a defined distance, which is greater than in the case of the first basic size, between the imaginary intersection line of the inner surface with the outer surface and the fire-side surface, and by providing at least three positions within each basic size, wherein the sized bricks of different positions have lateral surfaces which are inclined differently to one another, and wherein the sized bricks of one position have parallel lateral surfaces.
