## Abstract

Fluid containing support members of walking beam mechanisms for moving beams and the like in furnaces are insulated with refractory ceramic fiber blanket modules. The modules are wrapped about the support members and attched with attachment members. Protective coverings are provided to reduce exposure of the fiber materials from slag from the beams.

## Claims

### Claim 1

A method of installing refractory ceramic fiber module, composed of a folded blanket of refractory ceramic fiber extending between two end folds and having attachment members extending outwardly from said folds, to a support tube which supports a metal member during movement of the member in a furnace comprising the steps of:
(a) wrapping the blanket of the module about the tube; and
(b) attaching the attachment members to the tube.

### Claim 2 (depends on 1)

The method of claim 1, wherein said step of attaching comprises:
welding the attachment members to the tube.

### Claim 3 (depends on 1)

The method of claim 1, wherein said step of attaching comprises:
bolting the attachment members to the tube.

### Claim 4 (depends on 1)

The method of claim 1, wherein said step of attaching comprises:
attaching the attachment members to the tube at positions leaving portions of the tube uncovered by the blanket.

### Claim 5 (depends on 4)

The method of claim 4, further including the step of:
insulating the uncovered portions of the tube.

### Claim 6 (depends on 5)

The method of claim 5, wherein said step of insulating comprises:
applying a refractory mortar to the uncovered portions of the tube.

### Claim 7 (depends on 5)

The melthod of claim 5, wherein said step of insulating comprises:
(a) applying an inner layer of refractory ceramic fiber blanket to the uncovered portions of the tube; and
(b) covering the inner layer with a refractory mortar.

### Claim 8 (depends on 5)

The method of claim 5, wherein sad step of insulating comprises:
(a) applying refractory blanket stuffing to cover at least a portion of the uncovered portion of the tube;
(b) covering the stuffing with a protective member; and
(c) attaching the protective member to the tube.

### Claim 9 (depends on 5)

The method of claim 5, wherein said step of insulating comprises:
(a) applying refractory blanket stuffing to cover at least a portion of the uncovered portion of the tube;
(b) covering the stuffing and portions of the blanket with a protective member; and
(c) attaching the protective member to the tube.

### Claim 10 (depends on 1)

The method of claim 1, further including the steps of:
(a) forming a pocket between the blanket and the tube during said step of wrapping; and
(b) inserting refractory fiber insulation material into the pocket so formed.

### Claim 11 (depends on 1)

The metod of claim 1, wherein the tube has a skid rail member extending upwardly therefrom and the attachment members extend along the length of the folded blanket and outwardly from the blanket, at its ends and said step of attaching comprises:
attaching the attachment members to the skid rail member.

### Claim 12 (depends on 1)

The method of claim 1, wherein the attachment members extend outwardly through the blanket from the folds, and said step of attaching comprises:
attaching the attachment members to the tube at positions leaving portions of the tube uncovered by the blanket.

### Claim 13 (depends on 1)

The method of claim 1, wherein the attachment members extend outwardly through the blanket from the folds, and the tube has mounting ribs extending outwardly from side portions thereof, and said step of attaching comprises:
attaching the attachment members to the mounting ribs.
