Abstract

A refractory article can include a socket including a cavity that is configured to receive a post, a particulate material, and a binder. The binder is configured to bond the post to the socket. The refractory article can include a sleeve coupled to the socket and configured to bond the post to the socket. In an embodiment, the sleeve can bond to the binder. In another embodiment, a collar can be placed between the sleeve and the binder. The collar can be configured to bond the post to the socket. A method of forming a refractory article can include disposing a particulate material within a cavity of a socket and placing a binder material overlying the particulate material.

First claim

What is claimed is:

1. A refractory article, comprising:
a socket comprising a cavity configured to receive a post;
a particulate material contained within the cavity;
a binder disposed above the particulate material and configured to bond the post to the socket;
and

a sleeve coupled to the socket.

2. The refractory article of claim 1 , wherein the sleeve is abutting the socket and configured to bond the post to the socket.

3. The refractory article of claim 1 , wherein the sleeve is fastened to the socket.

4. The refractory article of claim 1 , wherein the sleeve is bonded to the binder.

5. The refractory article of claim 1 , wherein the sleeve is spaced apart from the binder.

6. The refractory article of claim 1 , further comprising a collar overlying the socket and configured to bond the post to the socket.

7. The refractory article of claim 6 , wherein the collar is disposed between the binder and the sleeve.

8. The refractory article of claim 1 , wherein the socket comprises a bottom wall comprising alumina, cordierite, mullite, a castable material, cement, fiber, or any combination thereof.

9. The refractory article of claim 1 , wherein the socket comprises a side wall comprising metal, metal alloy, silicon carbide, or a combination thereof.

10. The refractory article of claim 1 , wherein the particulate material comprises at least one of a ceramic, glass, polymer, metal, metal alloy, or a combination thereof.

11. The refractory article of claim 1 , wherein the particulate material comprises a silicon carbide, alumina grains, mullite grains, or any combination thereof.

12. The refractory article of claim 1 , wherein the binder comprises a refractory material.

13. The refractory article of claim 12 , wherein the refractory material comprises alumina.

14. The refractory article of claim 1 , wherein the collar, sleeve, or both comprise metal, metal alloy, silicon carbide, alumina, or a combination thereof.

15. A method forming a refractory article, comprising:
disposing a particulate material within a cavity of a socket;
placing a binder material overlying the particulate material and
coupling a sleeve to the socket.

16. The method of claim 15 , comprising fastening the sleeve to the socket.

17. The method of claim 16 , comprising drying the binder material and bonding the sleeve to the socket.

18. The method of claim 15 , comprising placing a collar overlying the socket.

19. The method of claim 18 , comprising drying the binder material and bonding the collar to the socket.

20. The refractory article of claim 1 , wherein the collar, sleeve, or both comprise an alloy including iron.
