Abstract
One embodiment of the present invention discloses a method for operating a mill train, in particular used in a cold-rolling mill. The mill train includes operating rolls with a roll gap disposed in-between through which a rolled strip is guided. With the method of at least one embodiment, the thickness and the roll-in speed of the rolled strip are measured in front of the roll gap. The roll-out speed of the rolled strip after the roll gap is reconstructed with the aid of the tangential speed of the operating rolls. The thickness after the roll gap is then determined with the aid of the thickness and the roll-in speed in front of the roll gap and the reconstructed roll-out speed.
Claims18
A method for operating a mill train, wherein the mill train includes operating rolls, with a roll gap disposed in-between, through which a rolled strip is guided, the method comprising:
- measuring a thickness and a roll-in speed of the rolled strip in front of the roll gap;
- reconstructing a roll-out speed of the rolled strip, after the roll gap, with the aid of a tangential speed of the operating rolls;
- and
- determining the thickness after the roll gap with the aid of the measured thickness and the roll-in speed in front of the roll gap and the reconstructed roll-out speed.
A computer program product comprising a non-transitory computer readable medium having computer readable program codes embodied in the medium that, when executed, cause a computer to implement a method for operating a mill train, wherein the mill train includes operating rolls, with a roll gap disposed in-between, through which a rolled strip is guided, the method comprising:
- measuring a thickness and a roll-in speed of the rolled strip in front of the roll gap;
- reconstructing a roll-out speed of the rolled strip, after the roll gap, with the aid of a tangential speed of the operating rolls;
- and
- determining the thickness after the roll gap with the aid of the measured thickness and the roll-in speed in front of the roll gap and the reconstructed roll-out speed.
A digital computer provided with a memory including a computer program having instructions for implementing a method for operating a mill train, wherein the mill train includes operating rolls, with a roll gap disposed in-between, through which a rolled strip is guided, the method comprising:
- measuring a thickness and a roll-in speed of the rolled strip in front of the roll gap;
- reconstructing a roll-out speed of the rolled strip, after the roll gap, with the aid of a tangential speed of the operating rolls;
- and
- determining the thickness after the roll gap with the aid of the measured thickness and the roll-in speed in front of the roll gap and the reconstructed roll-out speed, when executed on the computer.
A mill train, comprising:
- an electronic circuit configured to realize a method for operating a mill train, wherein the mill train includes operating rolls, with a roll gap disposed in-between, through which a rolled strip is guided, the method including
- measuring a thickness and a roll-in speed of the rolled strip in front of the roll gap;
- reconstructing a roll-out speed of the rolled strip, after the roll gap, with the aid of a tangential speed of the operating rolls;
- and
- determining the thickness after the roll gap with the aid of the measured thickness and the roll-in speed in front of the roll gap and the reconstructed roll-out speed.
