Method for producing a metal strip using a casting rolling assembly and control and/or regulating device for a compound casting rolling assembly

Abstract

Producing a metal band using a casting roller composite plant, comprises casting a metal by a casting device (1, 1'), and hot forming the metal bands by at least one rolling mill (2). The casting roller composite plant is operated so that the metal band extends continuously between the casting device and the rolling mill. The metal band is continuously supplied to the rolling mill. The rolling mill has a desired thickness profile, according to which the rolling mill rolls the metal band. The thickness profile exhibits at least two different target thicknesses for different band sections. Producing a metal band using a casting roller composite plant, comprises casting a metal by a casting device (1, 1') and hot forming the metal bands by at least one rolling mill (2). The casting roller composite plant is operated so that the metal band extends continuously between the casting device and the rolling mill. The metal band is continuously supplied to the rolling mill. The rolling mill has a desired thickness profile, according to which the rolling mill rolls the metal band. The thickness profile exhibits at least two different target thicknesses for different band sections in the longitudinal direction of the metal band. The thickness profile is designed so that the first and / or the second target thickness are adjusted at least twice. Independent claims are also included for: (1) a control and / or regulating device (10) for a casting roller composite plant to produce longitudinally thick profiled metal strip, comprising a machine readable program code, which includes control commands and causes the control and / or regulating device to perform the method mentioned above; and (2) the casting roller composite plant to manufacture metal strip thick profiled in its longitudinal direction, comprising the casting device and the rolling mill, where the control and regulating device is operatively connected with the rolling mill.

Description

technical field [0001] The invention relates to a method for producing a rolled product, in particular a metal strip, by means of a strand direct rolling assembly comprising: a casting device for casting metal; and comprising at least one rolling stand Rolling mills for hot forming of metals, in which the billet direct rolling unit is operated in such a way that the rolling stock extends continuously between the casting unit and the rolling mill, wherein the rolling stock is continuously fed to the rolling mill machine, wherein a rated thickness variation curve is preset for the rolling mill, and the rolling mill rolls the rolled piece according to the rated thickness variation curve. Furthermore, the invention relates to a control device and / or a regulating device for a strand direct rolling assembly and a strand direct rolling assembly for producing a rolling stock whose thickness is profiled in its longitudinal direction. Background technique [0002] The present inventi...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is that the adjustment of the thickness with the casting rolls is inaccurate and difficult to control

In addition, only specific thickness variation curves can be produced

This limits the flexibility of the device

[0005] It is not currently possible to manufacture "spliced ​​panels" using conventional hot rolling mills

Because, the minimum achievable hot-rolled strip thickness is usually in the range between 1.2 and 1.5 mm, which is insufficient for spliced ​​plates which often require a minimum thickness of 0.6 mm

Therefore, for spliced ​​plates, the required thickness range can only be insufficiently met using conventional hot rolling mills.
