Abstract

A refractory component for forming a refractory lining includes a refractory brick, and a support member having at least one surface fixed to the refractory brick.

Claims (30)

1 . A refractory component for forming a refractory lining, comprising

a refractory brick; and

a support member having at least one surface fixed to the refractory brick.

2 . The refractory component according to claim 1 , wherein the support member is co-molded with the refractory brick.

3 . The refractory component according to claim 1 , further comprising a plurality of anchors, wherein the plurality of anchors fix the support member to the refractory brick.

4 . The refractory component according to claim 3 , wherein the plurality of anchors are integrally formed with the support member.

5 . The refractory component according to claim 3 , wherein the anchors comprise a positive lock.

6 . The refractor component according to claim 5 , wherein the positive lock comprises at least one of a hook, a wave rod, a tapered rod, or a headed rod.

7 . The refractory component according to claim 1 , wherein the support member comprises a steel plate.

8 . The refractory component according to claim 1 , wherein the support member comprises a planar member.

9 . The refractory component according to claim 8 , wherein the planar member is at least one-quarter inch thick.

10 . The refractory component according to claim 1 , wherein the at least one of the anchors or the support member is pressed into the brick.

11 . The refractory component according to claim 1 , wherein the refractory brick comprises a resin brick, a pitch bonded brick.

12 . The refractory component according to claim 11 , wherein the brick comprises a magnesium-carbon brick or an alumina-carbon brick.

13 . The refractory component according to claim 1 , further comprising at least one mounting tab attached to the support member, the at least one mounting tab configured to mount the refractory component to a support structure.

14 . A Ruhrstahl-Heraeu (RH) snorkel, comprising:

a snorkel can having an inner radial surface, an outer radial surface, a top surface and a bottom surface; and

an outer lining attached to at least one of the outer radial surface, or the bottom surface, where the outer lining is formed from a plurality of refractory components according to claim 1 .

15 . The RH snorkel according to claim 14 , wherein the snorkel comprises a cylinder.

16 . The RH snorkel according to claim 14 , further comprising a cooling device arranged on the outer radial surface of the snorkel can.

17 . The RH snorkel according to claim 14 , further comprising a monolithic refractory disposed at least in a space between the outer radial surface of the snorkel can and the refractory component.

18 . A method of forming a refractory component for a Ruhrstahl-Heraeu (RH) snorkel, comprising:

fixedly attaching a support member to a refractory brick; and

attaching a plurality of mounting tabs to the support member.

19 . The method according to claim 18 , further comprising securing the plurality of mounting tabs to an outer surface of the RH snorkel.

20 . The method according to claim 18 any one of claims 18-19 , wherein fixedly attaching includes pressing the support member into the brick.

21 . The method according to claim 18 , wherein fixedly attaching includes placing a first surface of the support member against a first surface of the refractory brick, and pressing anchors through the support member and into the refractory brick to secure the support member to the refractory brick.

22 . The method according to claim 18 , wherein fixedly attaching includes co-molding the support member with the refractory brick.

23 . The method according to claim 22 , wherein co-molding the support member into the refractory brick includes attaching anchors to the support member, and co-molding the support member and anchors into the refractory brick.

24 . The method according to claim 18 , further comprising attaching mounting tabs to a second surface of the support member.
