Abstract

The invention relates to a thermal insulation device (1) for thermal insulation of a metal product in a rolling mill, comprising a support element (2), on which a number of thermal insulation elements (3) is arranged. To extend the service life of such a device, the invention makes provision that at least one thermal insulation device (3) is formed by multiple side parts (4, 5, 6, 7, 8, 9), which enclose within them an accommodating space for a thermal insulation material, wherein at least two of the side parts (4, 5, 6, 7, 8, 9) are connected with each other at their adjoining side areas by a hinge-like connection (10).

First claim

The invention claimed is:

1. A thermal insulation device for thermal insulation of a metallic product in a rolling mill, comprising:
a support element;
at least one thermal insulation element; and
a thermal insulation material;
wherein each of the at least one thermal insulation elements are formed by multiple side parts which circumferentially enclose an accommodating space configured to hold the thermal insulation material,
wherein at least two of the side parts are connected to each other along adjoining sides by a connection adapted for pivoting the at least two side parts relative to each other, and
wherein the support element is configured to suspend and arrangement of the at least one thermal insulation element above the metallic product in the rolling mill.

2. The thermal insulation device of claim 1 , characterized in that the connection is formed by a number of hinges, which are arranged along the adjoining side areas.

3. The thermal insulation device of claim 2 , characterized in that each of the number of hinges is defined by a length and a diameter, with the length being at most 10 times the diameter.

4. The thermal insulation device of claim 1 , characterized in that the connection is formed by at least one spiral-shaped wire, which is threaded into boreholes that are made along the adjoining side areas.

5. The thermal insulation device of claim 1 , characterized in that the connection is formed by an at least sectional weakening of a mechanical strength, of at least one of the at least two side parts.

6. The thermal insulation device of claim 5 , characterized in that the at least one of the at least two side parts is a longitudinal plate extending along a longitudinal extent of the thermal insulation device, wherein the weakening is produced by at least one recess in the at least one of the longitudinal plates.

7. The thermal insulation device of claim 5 , characterized in that the at least one of the at least two side parts is a longitudinal plate extending along a longitudinal extent of the thermal insulation device, wherein the weakening results from the at least one of the longitudinal plates being assembled from at least two separate side piece sections connected with each other.

8. The thermal insulation device of claim 1 , characterized in that the side parts are formed by metal plates.

9. The thermal insulation device of claim 1 , characterized in that the thermal insulation material is formed at least in part by ceramic fibers.

10. The thermal insulation device of claim 1 , characterized in that a plurality of the number of thermal insulation elements are arranged both in a direction transverse to a feed direction of the metallic product and also in the feed direction of the metallic product.

11. The thermal insulation device of claim 1 , characterized in that at least one of the thermal insulation elements viewed in a feed direction of the metallic product, has a square, rectangular or trapezoidal shape.

12. The thermal insulation device of claim 1 , characterized in that the multiple thermal insulation elements are arranged next to each other in a direction transverse to a feed direction of the metallic product, wherein at least two adjoining ones of the multiple thermal insulation elements have a joint side part.

13. The thermal insulation device of claim 1 , characterized in that the multiple thermal insulation elements are arranged in a direction transverse to a feed direction of the metallic product and are penetrated by at least one rod.

14. The thermal insulation device of claim 13 , characterized in that the at least one rod penetrates lateral sections of the support element extending in a vertical direction, and is secured on the support element by attachment elements.

15. The thermal insulation device of claim 14 , wherein the attachment elements are bolts.

16. The thermal insulation device of claim 1 , characterized in that a gap is present in a vertical direction between the number of thermal insulation elements and the support element.

17. The thermal insulation device of claim 16 , characterized in that the gap is at least partially filled with insulating wool.

18. The thermal insulation device of claim 17 , characterized in that when the-insulating wool is placed in the gap, an extension of the gap in the vertical direction at most is 100 mm.

19. The thermal insulation device of claim 16 , characterized in that the gap is penetrated in the vertical direction by a number of connection elements, which are attached on the support element and on the thermal insulation elements.

20. The thermal insulation device of claim 19 , wherein the connection elements are spacer bolts.

21. The thermal insulation device of claim 16 , wherein the gap has a width of at most 30 mm.

22. The thermal insulation device of claim 16 , wherein the gap is at least partially filled with biocompatible ceramic fibers.

23. The thermal insulation device of claim 1 , characterized in that a plate thickness of the side parts differs at least in part.

24. The thermal insulation device of claim 23 , wherein the side parts comprise first side parts extending in a feed direction of the metallic product and second side parts extending perpendicular to the feed direction, and wherein the first side parts are thicker than the second side parts.

25. The thermal insulation device of claim 1 , characterized in that the number of thermal insulation elements in a direction transverse to a feed direction of the metallic product at least in part differ in width.

26. The thermal insulation device of claim 1 , characterized in that in a feed direction of the metallic product at least two of the number of thermal insulation elements are arranged to follow each other, wherein the two thermal insulation elements following each other in the feed direction have corresponding side parts that are configured to be different in thickness.

27. The thermal insulation device of claim 1 , wherein the connection is formed by an at least sectional weakening of a flexural strength of at least one of the at least two side parts.
