Another possibility is to drive the guide elements as tightly as possible, but this has limits as the sheets are usually wide at the top and ends and get stuck in the side guides

Embodiment Construction

[0029] exist figure 1 A rolling stand 2 of a thin-strip rolling mill, not further shown here, is shown symbolically, by means of which the sheet metal 4 is rolled. The rolling stand 2 is characterized by a drive side OS and a control side DS. The sheet rolling mill comprises a plurality of such rolling stands 2 which are arranged consecutively along a center line M in a rolling direction 6 . During rolling, the sheet metal 4 is transported in the rolling direction 6 . In this case, each next rolling pass is usually carried out on the respective next rolling stand 2 in the rolling direction 6 .

[0030] The sheet metal 4 has two end faces 8 , 10 and two side faces 12 , 14 . Depending on which end face enters the respective rolling stand 2 as the first and second end face, the end faces are referred to as top and end. top according to figure 1 and figure 2 refers to the end face 8 , while the end is formed by the opposite end face 10 .

[0031] Ideally, the sheet 4 is re...

Abstract

The method involves detecting whether side surfaces (12, 14) of a parallelogram shaped board (4) are offset relative to each other in a rolling direction (6) during discharging the board from a rolling stand (2). Guide elements (16, 18) are asymmetrically adjusted relative to a middle line (M) after centering during a rolling pass when the side surfaces are offset relative to each other. One of the guide elements (18) for one of the side surfaces (14), which enters into the stand as first during the rolling pass, is displaced from the middle line as the other guide element. Independent claims are also included for the following: (1) a computer program comprising instructions for performing a method for rolling boards by a rolling stand (2) a data carrier comprising instructions for performing a method for rolling boards by a rolling stand (3) a control device.

Description

technical field [0001] The invention relates to a method for rolling sheet metal by means of at least one rolling stand. The invention also relates to a computer program, a data carrier and a control device for a rolling stand. Background technique [0002] Guide elements are provided on the sides for the straight edge guidance of a rectangular plate in the rolling stand of a sheet rolling mill, said guide elements providing a straight, symmetrical course of the plate. This guide element acts as a center and then "rises" slightly again. Here, they do not rest directly on the side of the sheet metal, but are positioned at a distance from the side, so that a gap of several centimeters width, in particular 3 to 5 cm, is formed between the guide element and the side of the sheet metal. When rolling rectangular plates or sheets, it often happens that the edges of the sheets do not enter the roll gaps in the rolling stands of the sheet rolling mill with straight edges. This occ...
