Embodiment Construction

[0027] figure 1 A hot-rolled strip coil 1 consisting of a coiled hot-rolled strip 2 is shown. The hot strip coil 1 has an axis S of symmetry. The axis of symmetry S runs perpendicular to the plane of the drawing through the center of the hot-rolled strip coil 1 .

[0028] The hot strip coil 1 is supported on three movable rollers. exist figure 1 One of these rollers is configured as drive roller 7 . The other two rollers are designed as passive, rotatably mounted support rollers 3 . Both the drive roll 7 and the other two support rolls 3 are solid elements which are in contact with a part of the side face 5 of the hot strip coil 1 . The hot strip coil 1 can be rotated about its axis of symmetry S by means of the drive roll 7 . Roller 3 or 7 is designed such that its side height is at least as large as the side height of hot-rolled strip coil 1 in the exemplary embodiment, that is to say said roller is on the side face 5 of hot-rolled strip coil 1 on the whole side height...

Abstract

The invention relates to a method for cooling a hot strip wound to a hot strip bundle, a device for cooling a hot strip bundle, a control and/or regulating device, and a metal strip. The invention relates to a device for cooling a hot strip bundle (1), a metal strip, a control and/or regulating device for a device for cooling a hot strip bundle (1), and to a method for cooling a hot strip (2) wound to a hot strip bundle (1), wherein the hot strip bundle (1) is twisted (100) and cooled by means of contact of the lateral surface (5) thereof with at least one element (3, 7). By twisting the hot strip bundle (1) about the axis of symmetry (S) thereof, a method and a device can be provided by means of which homogenous strip properties may be obtained for a cooling hot strip bundle in a compact manner.

Description

technical field [0001] The invention relates to a method for cooling a hot-rolled strip coiled into a hot-rolled strip coil by means of an intermediate support device different from a coiler. Furthermore, the invention relates to a device for cooling a hot-rolled strip coil and a control and / or regulating device for a device for cooling a hot-rolled strip coil. Finally, the invention relates to a metal strip. Background technique [0002] When hot-rolled strip is produced by means of a hot-rolling train, the hot-rolled strip is usually wound up on a coiler to form a hot-rolled strip coil at the end of the hot-rolling train. In this case, the hot-rolled strip usually already passes through a cooling section in which the desired structure and thus its properties of the hot-rolled strip are set. Examples of metals treated by such processes are steel, aluminum and copper. However, other strips of other metals are also processed in the hot rolling train. [0003] Especially f...
