Abstract
A unitary refractory ring having a sidewall surrounding and spaced from a center axis, and one or more lifting lugs distributed around the center axis. The lifting lugs extend from an inner face of the sidewall towards the center axis, and are located between lower and upper axial faces of the sidewall. Each lifting lug has a lower lug face extending radially towards the center axis from the inner face of the sidewall, and a backing structure extending upwards along an axial direction from the lower lug face towards the upper axial face of the sidewall. An assembly of refractory rings, and methods for making and assembling refractory rings are also provided.

A replaceable refractory ring-shaped liner adapted for lifting and placement within a cavity of a metallurgical vessel to form a section of an inner wall of the metallurgical vessel, the ring-shaped liner comprising:
- a continuous top surface;
- a continuous bottom surface;
- a continuous arcuate inner surface extending from the top surface to the bottom surface and defining a cavity, wherein the inner surface contacts material that is disposed within the metallurgical vessel;
- and a continuous arcuate outer surface opposite the inner surface and extending between the top surface and the bottom surface;
- wherein the inner surface comprises a plurality of protrusions intermediate the top surface and the bottom surface and extending into the cavity;
- wherein a plurality of spacings are defined between the protrusions of the plurality of protrusions;
- and wherein the ring-shaped liner comprises a heat resistant, refractory material and is configured to prevent passage of molten material through the inner surface to the outer surface.
