Abstract

A refractory article including a body having central opening extending through at least a portion of the body, the central opening having a receiving surface having a convex curvature. In an embodiment, the body can include a coupling protrusion extending from a portion of an upper surface of the body and a coupling depression on a portion of a bottom surface of the body.

First claim

What is claimed is:

1 . A refractory article comprising:
a body including:
an upper surface;
a bottom surface;
a side surface extending between the upper surface and bottom surface, wherein the side surface comprises an elliptical contour;
a central opening extending through at least a portion of the body;
a coupling protrusion extending from a portion of the upper surface; and
a coupling depression on a portion of the bottom surface.

2 . The refractory article of claim 1 , wherein the body comprises a ceramic including a carbide, a boride, a nitride, an oxide, or any combination thereof.

3 . The refractory article of claim 1 , wherein the body comprises silicon carbide.

4 . The refractory article of claim 1 , wherein the upper surface comprises a first upper surface portion and a second upper surface portion, wherein the central opening separates the first upper portion and second upper portion.

5 . The refractory article of claim 4 , wherein the coupling protrusion includes a first coupling protrusion portion on the first upper surface portion and a second coupling protrusion portion on the second upper surface portion, and wherein the central opening separates the first coupling protrusion portion and the second coupling protrusion portion.

6 . The refractory article of claim 5 , wherein the coupling protrusion comprises a tapered shape as viewed in cross-section.

7 . The refractory article of claim 1 , wherein the coupling depression defines a cavity having a taper angle greater than 90 degrees.

8 . A high temperature storage system, comprising a plurality of the refractory articles of claim 1 including a first refractory article and a second refractory article, wherein the coupling protrusion of the first refractory article is disposed within the coupling depression of the second refractory article, and the body of the first refractory article and the body of the second refractory article are configured to rotate relative to each other while engaged.

9 . A refractory article comprising:
a body having central opening extending through at least a portion of the body, the central opening defined by a first inner side surface, second inner side surface, and a receiving surface extending between the first inner side surface and second inner side surface, wherein at least a portion of the receiving surface comprises a convex curvature.

10 . The refractory article of claim 9 , wherein the body includes an upper surface, a bottom surface, and a side surface extending between the upper surface and bottom surface, and further comprises a coupling protrusion extending from a portion of the upper surface, and a coupling depression on a portion of the bottom surface.

11 . The refractory article of claim 10 , wherein the side surface comprises an elliptical contour.

12 . The refractory article of claim 10 , wherein the side surface comprises a circular contour.

13 . The refractory article of claim 9 , wherein the coupling depression has a depth, and the coupling protrusion has a height, and wherein the depth is greater than 50% of the height and not greater than 200% of the height.

14 . The refractory article of claim 13 , wherein the height is within a range of at least 1 mm to not greater than 50 mm, and wherein the depth is within a range of at least 1 mm to not greater than 100 mm.

15 . The refractory article of claim 9 , wherein the coupling depression has a width, and the coupling protrusion has a width, and wherein the width of the coupling depression is at least 2% greater than the width of the coupling protrusion and not more than 90% greater than the width of the coupling protrusion.

16 . The refractory article of claim 15 , wherein the coupling depression comprises a width of at least 2 cm and not greater than 200 cm, and wherein coupling protrusion comprises a width of at least 1 cm or at least 2 cm and not greater than 150 cm.

17 . A refractory article comprising:
a body including:
an upper surface;
a bottom surface;
a central opening extending through at least a portion of the body;
a coupling protrusion extending from a portion of the upper surface; and
a coupling depression on a portion of the bottom surface, wherein the coupling depression defines a cavity having a taper angle greater than 90 degrees.

18 . The refractory article of claim 17 , wherein the central opening is defined by a first inner side surface, second inner side surface, and a receiving surface extending between the first inner side surface and second inner side surface, wherein at least a portion of the receiving surface comprises a convex curvature.

19 . The refractory article of claim 17 , wherein the body further comprises a secondary opening spaced apart from the central opening and disposed between the bottom surface and the central opening.

20 . The refractory article of claim 17 , wherein the body comprises alpha-phase silicon carbide.
