Abstract

Various embodiments of the present inventions encompass a variety of methods and devices for attaching labels, tags, or identification devices to hot metals.

Claims

1. A high temperature resistant label for use in identifying hot metal comprising:

a high temperature resistant material comprising;

at least one layer of glass fabric material;

at least one layer of mica paper; and

a polymeric adhesive, said adhesive securing said glass fabric material to said mica paper, wherein said high temperature resistant material is formed to a desired size and shape;

an identification means applied to one side of said high temperature resistant material;

a thin metal layer formed to the same size and shape as said high temperature resistant material, said thin metal layer is attached to the other side of said high temperature resistant material opposite said identification means; and

an attachment means wherein the attachment means is metal fasteners;

wherein the high temperature label remains attached to the surface of metals having a temperature between 900-1000°

C., and wherein said high temperature resistant material is attached to said thin metal layer by an attachment means, wherein said attachment means is provided by said metal fasteners, which act to secure said high temperature resistant material to said thin metal layer and protrude through said thin metal layer to contact and bond with said hot metal as said hot metal cools.

2. The high temperature resistant label of claim 1, wherein said glass fabric material comprises glass cloth.

3. The high temperature resistant label of claim 1, wherein said polymeric adhesive comprises a silicone polymer.

4. The high temperature resistant label of claim 3, wherein said glass fabric material has a thickness of about 30 microns to about 100 microns and said mica paper has a thickness of about 40 microns to about 80 microns.

5. The high temperature resistant label of claim 1, wherein said high temperature resistant material has a thickness of about 70 microns to about 200 microns.

6. The high temperature resistant label of claim 1, wherein said polymeric adhesive is applied under pressure to secure said glass fabric material to said mica paper.

7. The high temperature resistant label of claim 1, wherein said identification means is selected from the group consisting of a bar code, a symbol, words, numbers, an alphanumeric combination, and an imprint.

8. The high temperature resistant label of claim 1, wherein said thin metal layer is selected from the group consisting of metal foil, aluminum, steel, copper, a metal alloy and magnets.

9. The high temperature resistant label of claim 1, wherein said metal fasteners are selected from the group consisting of screws, nails, pins and nut and bolt assemblies.
