Abstract

The invention relates to an intermediate stand guide ( 3 ) on a vertical roll stand ( 1 ) of a rolling line for guiding the rolled material into a horizontal roll stand ( 2 ) or out of a horizontal roll stand ( 2 ) having at least one guide element ( 4 ), which is mounted on the vertical roll stand ( 1 ) and is adjustable jointly with an adjustment movement of a vertical roll ( 6 ) assigned thereto and which follows the adjustment movement of the vertical roll ( 6 ), wherein the guide element ( 4 ) is arranged set back transversely to the rolling direction by a predefined offset dimension (X′) to the edge of the vertical roll ( 6 ) engaged with the rolled material, wherein the guide element ( 4 ) is connected to a traverse ( 5 ) of the vertical roll stand ( 1 ) and the offset dimension (X′) is pre-definable via an installation distance of the vertical roll ( 6 ) to the traverse ( 5 ) of the vertical roll stand ( 1 ).

First claim

The invention claimed is:

1 . An intermediate stand guide on a vertical roll stand of a rolling line for guiding the rolled material using at least one guide element, which is mounted on the vertical roll stand and is adjustable jointly with an adjustment movement of a vertical roll assigned thereto and which follows the adjustment movement of the vertical roll, wherein the guide element is arranged set back transversely to the rolling direction by a predefined offset dimension to the edge of the vertical roll engaged with the rolled material, wherein the guide element is connected to a traverse of the vertical roll stand and the offset dimension is pre-definable via an installation distance of the vertical roll to the traverse of the vertical roll stand, and wherein the at least one guide element is connected to a horizontal roll stand in addition to being fastened to the vertical roll stand;
wherein the installation distance of the vertical roll to the traverse of the vertical roll stand is pre-definable by means of one or more compensation plates of predefined thickness; wherein at least one compensation plate is detachably connected to a chock accommodating the vertical roll.

2 . The intermediate stand guide as claimed in claim 1 , wherein the guide element is fastened on the traverse using an overload safeguard.

3 . The intermediate stand guide as claimed in claim 1 , wherein at least one intended breakpoint and/or at least one other yielding fastening of the guide element is provided as an overload safeguard.

4 . The intermediate stand guide as claimed in claim 1 , wherein the guide element is connected to the traverse of the vertical roll stand via a connecting part.

5 . The intermediate stand guide as claimed in claim 4 , wherein the fixing of the connecting part relative to the traverse is made adjustable transversely to the rolling direction.

6 . The intermediate stand guide as claimed in claim 1 , wherein the guide element is mounted at least in one upper and/or lower guide bed of a vertical roll stand post of the vertical roll stand.

7 . The intermediate stand guide as claimed in claim 6 , wherein the guide element is mounted in a sliding manner in the upper and/or lower guide bed of the vertical roll stand post.

8 . The intermediate stand guide as claimed in claim 1 , wherein the position of the guide element is adjustable relative to the vertical roll.

9 . The intermediate stand guide as claimed in claim 1 , wherein the guide element has an L-shaped or C-shaped guide profile.

10 . The intermediate stand guide as claimed in claim 1 , wherein the guide element is supported at least on one side on a guide table.

11 . The intermediate stand guide as claimed in claim 10 , wherein the guide element is supported via at least one plain bearing so it is displaceable on the guide table.

12 . The intermediate stand guide as claimed in claim 1 , wherein the guide element has at least one replaceable wear plate.

13 . A method for guiding the rolled material in a rolling line using an intermediate stand guide as claimed in claim 1 , wherein the offset dimension is set via a detected installation distance of the vertical roll to the traverse of the vertical roll stand.

14 . The method as claimed in claim 13 , wherein the adjustment movement of at least one vertical roll of the vertical roll stand is monitored by sensors to set and monitor the position of the vertical roll and/or the guide element.

15 . The method as claimed in claim 1 , wherein the movement and/or position of the guide element is monitored relative to the position of the vertical roll.

16 . The method as claimed in claim 1 , wherein wear of the vertical roll and/or the guide profiles is detected by sensors and taken into consideration in the adjustment of the vertical roll and/or the guide elements.

17 . The intermediate stand guide as claimed in claim 1 , wherein the position of the guide element is hydraulically adjustable relative to the vertical roll, and wherein the guide element is supported at least on one side on a guide table mounted on a horizontal roll stand post of the horizontal roll stand.
