Refractory ring structure and related method

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 continuous protrusion intermediate the top surface and the bottom surface and extending into the cavity;
• 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.
