Embodiment Construction

[0065] figure 1 In side view, that is to say seen on the end faces of the casting rolls 2a, 2b, the arrangement for positioning the two casting rolls 2a, 2b opposite to each other around their longitudinal casting roll axes 2a', 2b' is schematically shown. device 1. The device 1 is a so-called twin-roll casting device, in which molten metal 4 is poured from a metal melting vessel 3 arranged above the device 1 into a casting gap 9 between two cooling casting rolls 2a, 2b rotating opposite each other. The molten metal 4 is conveyed to the casting rolls 2a, 2b via at least one nozzle arrangement 3a arranged above the casting gap 9, wherein a so-called casting pool 4a is formed above the casting gap 9 between the casting rolls 2a, 2b. The term "casting gap" 9 here refers to the region where the distance between the surfaces of the casting rolls or the gap width 9a is the smallest. Typically, the gap width 9 a of the casting gap 9 is approximately in the range of <10 mm, in part...

Abstract

The invention relates to a device and a method for positioning at least one of two casting rolls in a continuous casting process for producing metal strip. The device and the method make it possible to adjust or change the casting gap between the casting rolls during operation and thus to have an influence on the strip thickness and the strip profile of the metal strip produced.

Description

technical field [0001] The invention relates to a device for positioning at least one of two casting rolls for the production of metal strip. The invention also relates to a method for positioning at least one of two casting rolls during a casting process for producing a metal strip. Background technique [0002] A device and a method of the type mentioned at the outset are already known from DE 698 13 424 T2. The continuous casting of metal strip is described here with the aid of a twin-roll casting device in which molten metal is introduced into the casting gap between two opposing, rotating and cooled casting rolls or casting rolls. The molten metal is fed onto the casting rolls via at least one nozzle arrangement arranged above the casting gap, a so-called casting pool forming above the casting gap between the casting rolls. The term "casting gap" here refers to the area where the distance between the surfaces of the casting rolls is the smallest. In this case, the us...
