Abstract

The invention relates to a rolling device (1) comprising at least two working rollers (2, 3) and a roll gap (4) between the working rollers (2, 3) for guiding through and rolling a rolling stock (5) such as, for example, a strip (6) preferably of metal and optionally an arrangement of support rollers (7, 8), wherein furthermore at least one measuring device (11) is provided for measuring a backslip of the rolling material of the rolling stock in front of the roll gap (4), wherein furthermore a control or regulating unit (13) is provided which drives control members for adjusting the flatness of the rolling stock on the basis of the signals of the measuring device (11).

Claims (9)

1. A rolling device (1) comprising at least two working rollers (2, 3) and a roll gap (4) between the working rollers (2, 3) for guiding through and rolling a rolling stock (5) such as, for example, a strip (6) preferably of metal and optionally an arrangement of support rollers (7, 8), characterised in that furthermore at least one measuring device (11) is provided for measuring a backslip of the rolling material of the rolling stock in front of the roll gap (4), wherein furthermore a control or regulating unit (13) is provided which drives control members for adjusting the flatness of the rolling stock on the basis of the signals of the measuring device (11).
2. The rolling device (1) according to claim 1, characterised in that a flatness measuring device (12) is furthermore provided after the roll gap, which device provides signals for the control and regulating unit (13), whereupon these drive the control members (15, 16, 17, 18, 19) for adjusting the flatness of the rolling stock in response to the signals of the measuring device (11) and the flatness measuring device (12).
3. The rolling device according to claim 1, characterised in that the control member for adjusting the flatness of the rolling stock is a control member for adjusting the inclination of the working rollers (2, 3) and/or the support rollers (7 8), the flexure of the working rollers and/or the intermediate rollers (2, 3) and/or the support rollers (7, 8), the axial displacement of the working rollers (2, 3) and/or the intermediate rollers (2, 3) within the framework of a continuously variable crown (CVC) displacement, a minimal quantity lubrication and/or a temperature control or temperature regulations of the strip and/or the working rollers.
4 The rolling device according to one of the preceding claims, characterised in that at least one measuring device (11) for measuring a backslip of the rolling material of the rolling stock before the roll gap (4) is an optically or mechanically measuring device.
5. A method for operating a rolling device (1) comprising at least two working rollers (2, 3) and a roll gap (4) between the working rollers (2, 3) for guiding through and rolling a rolling stock (5) such as, for example, a strip (6) preferably of metal, characterised by detecting a backslip of the rolling material of the rolling stock before the roll gap (4) and triggering at least one control member for adjustment of the flatness of the rolling stock according to the detected backslip.
6. The method according to claim 5, characterised in that the adjustment of the flatness of the rolling stock is made with additional allowance for flatness measuring signals which represent the flatness of the rolling stock after the roll gap.
7. The method according to one of the preceding claims 5 or 6, characterised in that the backslip of the rolling material of the rolling stock before the roll gap (4) is detected optically or mechanically.
8. The method according to claims 1-6, characterised in that the strip tension situation is detected by means of a roller which dips into the strip, attached near the roll gap, for example, an anti-crimping roller.
9. The method according to claim 8 characterised by two load cells below the mounting of the roller for simultaneously detecting the difference strip tension for adjusting first-order flatness errors (inclination errors) and the global strip tensile stress or strip tensile force at the inlet of the roll mill.
