The invention relates to a device for determining the surface evenness of a strip in strip treatment installations, said device reducing the dead ranges, shortening the response time, increasing the process speed, and preventing the strip to be measured from being influenced during the measurement. To this end, the strip is guided over a tension roller for a strip treatment installation, and the traction exerted on the strip is increased or reduced between the feeding point of the tension roller and the delivery point of the tension roller, a measuring sensor arranged on the periphery of the tension roller being used to detect the tension distribution in the strip.

The invention relates to a strip coating method according to which the strip is guided through two opposite coils of a strip guiding device upstream or downstream of a coating device. Said strip guiding device comprises a position sensor for determining the position of the strip between the coils, current suppliers for the coils and a layer thickness sensor for determining the layer thickness of the coating applied to the strip. The inventive method comprises the following steps: determining a desired layer thickness profile, determining an actual layer thickness profile using the layer thickness sensor, determining a layer thickness control variable by comparing the actual layer thickness profile with the desired layer thickness profile, determining a desired position value for the strip position between the opposite coils using a higher order layer thickness controller whose input signal is the layer thickness control variable, determining an actual position value of the strip between the opposite coils using the position sensor, determining a position control difference by comparing the actual position value with the desired position value, impinging at least one of the coils with current, the current being adjusted in accordance with the output signal of a position controller whose input signal is the position control variable.

The invention relates to a method for determining the surface profile of a coated strip (5) which is transported through a device by a device and influenced by least one actuator, in addition to a method for regulating control variables for said process. Distance measurements are carried out in an offset manner and in relation to the direction in which the strip run, involving the following steps: the distance between the sensor (8) and the surface of the strip (5) is determined for at least one measuring point; the characterising values of a surface profile equation are calculated from the determined distance values by means of a switched Kalman filter; the surface profile of a coated strip guided through a device is determined in a precise manner and the adjustable variables are regulated in a precise manner.

Die Erfindung betrifft eine Vorrichtung zum Messen von Langprodukten in Walzwerken wie beispielsweise zum Erfassen der Geradheit, Dicke, Länge und Parallelität von Spezialprofilen, die mit Hilfe eines horizontal längs des Langkörpers (3) verfahrbaren Meßkopfes (4) und in dem Meßkopf (4) befindlichen Sensoren (15, 18, 19) eine Messung mit geringem Aufwand erlaubt und eine vollständige Automatisierung des Meßvorgangs ermöglicht.
摘要:
Bei einer Vorrichtung zum Richten von Metallband (5) mit parallel zueinander angeordneten Führungsrollen (1-4,6) befindet sich in dem Zwickel zweier Führungsrollen (2,6) eine Richtrolle (7), die das Band zwischen zwei Berührungslinien (9,10) formschlüssig umschlingt, längs derer die Führungsrollen über das Band in mittelbarer Berührung mit der Richtrolle stehen. Auf diese Weise ist es möglich, auch hochfestes Band zu richten, ohne daß Zugkräfte aufgebracht werden müßten, die das für den Transport des Bandes durch die Vorrichtung erforderliche Maß überschreiten.

Bei einer Vorrichtung zum Richten von Flanschprofilen, beispielsweise Doppel-T-Trägern, mit mehreren oberhalb und gegebenenfalls zusätzlich unterhalb des Richtguts (5) angeordneten Richtwerkzeugen (3,4;11,12;15,16), beispielsweise etwa T-förmigen Richtscheiben, zum Einleiten der Richtkraft in den Flansch verläuft die wirksame, die Richtkraft ausübende Mantelfläche (9) der Richtscheiben winklig in bezug auf die jeweilige Richtachse bzw. Flanschkante, während flanschstützende Flächen der Richtscheiben den Flansch seitlich abstützen.
