Abstract

A heat-insulating device for use in a processing line for a metal strip to be transported along a strip conveying direction, preferably for use in a rolling mill, wherein the heat-insulating device has: at least one heat-insulating carriage which has a heat-insulating hood which, in order to reduce temperature losses, can be moved over the metal strip; and a transport, which has a drive for moving the heat-insulating carriage and is configured in such a way that the heat-insulating carriage can be moved out of the processing line and into the latter horizontally, preferably along a straight line.

First claim

The invention claimed is:

1. A heat-insulating installation for use in a processing line for a metal strip to be transported along a strip-conveying direction, the heat-insulating installation comprising:
at least one heat-insulating carriage which has a heat-insulating hood that is fixed in a horizontal orientation and is movable in a horizontal direction over the metal strip for minimizing temperature losses; and
a transporting means which includes a drive for relocating the heat-insulating carriage and is configured so that the heat-insulating carriage is driveable horizontally out of and into the processing line, wherein the heat-insulating carriage has an undercarriage that lies opposite the heat-insulating hood so that the undercarriage is disposed below the metal strip when the driven-in heat-insulating carriage is moved over the metal strip.

2. The heat-insulating installation according to claim 1 , wherein the heat-insulating carriage is driveable horizontally along a straight line.

3. The heat-insulating installation according to claim 1 , wherein the transporting means includes at least one rail and/or bar and/or roller.

4. The heat-insulating installation according to claim 1 , wherein the drive is hydraulic and/or electric and/or pneumatic and/or a combination thereof.

5. The heat-insulating installation according to claim 1 , further comprising a roller way provided along the processing line and having a plurality of rollers for transporting the metal strip, wherein the heat-insulating carriage is movable into and out of an intermediate space between two neighboring rollers.

6. The heat-insulating installation according to claim 1 , wherein the heat-insulating carriage has lateral heat insulations which, conjointly with the heat-insulating hood, configure a profile that is U-shaped in a cross section perpendicular to the strip-conveying direction.

7. The heat-insulating installation according to claim 1 , wherein the undercarriage has overpass elements capable of being brought into contact with the metal strip in order for the metal strip to pass over in a driven-in state of the heat-insulating carriage.

8. The heat-insulating installation according to claim 7 , wherein the overpass elements are ribs and/or rollers.

9. The heat-insulating installation according to claim 6 , wherein the heat-insulating hood, the lateral heat insulations, and the undercarriage configure walls of a tunnel that surrounds a heat-insulating space and through which the metal strip passes in a driven-in state of the heat-insulating carriage.

10. The heat-insulating installation according to claim 9 , wherein the tunnel has a lateral slot, and/or at least one portion of the tunnel walls is provided such that said portion is openable and closeable.

11. The heat-insulating installation according to claim 6 , wherein at least one of the lateral heat insulations is mounted so as to be pivotable.

12. The heat-insulating installation according to claim 1 , wherein the heat-insulating carriage has a platform.

13. A system for processing a metal strip, comprising: a roll table having rollers for transporting the metal strip along a strip-conveying direction; and at least one heat-insulating installation according to claim 1 , the heat-insulating carriage of said heat-insulating installation being capable of being driven into and out of an intermediate space between neighboring rollers of the roll table.

14. The system according to claim 13 , further comprising at least one induction heater capable of being driven into and out of an intermediate space that is not occupied by the heat-insulating carriage.

15. The system according to claim 13 , wherein the heat-insulating installation includes a plurality of heat-insulating carriages, further comprising a connecting element that connects the plurality of heat-insulating carriages to one another to form a grouping so that group-wise driving-in and driving-out of the heat-insulating carriages is enabled.
