Abstract
A refractory brick that has a rear portion with a geometrical concavity on one side and a corresponding convex projection on the other side, the concavity and projection being matched so that the concavity mates with the corresponding projection of a similar refractory brick when the two are disposed in side-by-side relationship. Extending perpendicular from the base portion is a generally rectangular projection such that when a plurality of bricks are disposed in a side-by-side array, they are locked together by the mating concavities and projections, and the generally rectangular projections extend inwardly to form a thicker lining to withstand the force of a tap stream of molten metal for a longer duration.

An improved refractory brick comprising:
- (a) a base portion including:
- (i) a rear surface having a center and a first width across said rear surface, said first width being defined by rear portions of a side curved concave surface and an opposing side curved convex surface, the curvature of said concave surface being in mating geometrical relationship to said curved convex surface;
- (ii) a first essentially uniform vertical thickness, said first thickness being defined by an upper essentially planar surface and a lower essentially planar surface parallel to said upper surface;
- and
- (b) a semi-rectangular key or truncated wedge-shaped projection of thickness essentially equal to said first thickness extending from said base portion at a location opposite to that of said rear surfacer, said semi-rectangular projection having a front surface with a center, and wherein a centerline of said front surface and a center line of said rear surface are in axial alignment.
For an arcuate high temperature containment vessel, an improved refractory brick comprising:
- (a) a base portion including:
- (i) a slightly curved rear surface having a center and a first width across said rear surface, said first width being defined by rear portions of a side curved concave surface and an opposing side curved convex surface, the curvature of said concave surface being in mating geometrical relationship to said curved convex surface;
- (ii) a first essentially uniform vertical thickness, said first thickness being defined by an upper essentially planar surface and a lower essentially planar surface parallel to said upper surface;
- and
- (b) a semi-rectangular key or truncated wedge-shaped projection of thickness essentially equal to said first thickness extending from said base portion at a location opposite to that of said rear surface, said semi-rectangular projection having:
- (i) thickness defined by coplanar continuous extensions of said upper essentially planar surface and said lower essentially planar surface;
- and
- (ii) a front surface with a center;
- and wherein a centerline of said front surface and a center line of said rear surface are in axial alignment.
