Abstract
Description
Die trfindung betrifft eine Steuereinrichtung zum Zustellen der längsverschiebbaren Schleifscheibe einer Walzenschleifmaschine, auf der zum Nachschleifen die ungleichmäßigen Verschleiß aufweisende und unter ungleichmäßiger Temperaturverteilung über die Ballenlänge stehende Walze drehantreibbar eingespannt ist.The invention relates to a control device for adjusting the longitudinally displaceable grinding wheel of a Roll grinder on which for regrinding the uneven wear exhibiting and under uneven temperature distribution over the length of the bale standing roller is clamped to be driven in rotation.
In allen Flachwalzwerken müssen die Walzen nach einer bestimmten Zeit in den Walzenwerkstätten nachgeschliffen werden. Dieses Nachschleifen bezweckt, die beim Walzprozeß aufgetretene Abnutzung der Walzenoberfläche zu überarbeiten und die Walzenoberfläche und die Walzenform (Hohl- oder Balligschliff) wieder in den walztechnologisch notwendigen Zustand zu bringen.In all flat rolling mills, the rolls have to be reground after a certain period of time in the roll shops. The purpose of this regrinding is to rework the wear and tear on the roller surface that occurred during the rolling process and to bring the roller surface and the roller shape (hollow or crowned ground) back into the condition required for rolling technology.
Dazu müssen die Walzen z. B. an der Luft bis zum vollen Temperaturausgleich abkühlen, was Zeit in Anspruch nimmt und somit große Walzenparks und Bindung von Kapital bedeutet. Diese großen Walzenparks müssen vorhanden sein, damit immer fertig geschliffene Walzen zur Verfugung stehen.To do this, the rollers must z. B. cool in the air until full temperature equilibrium, which time in Claims and thus means large roll parks and capital commitment. These big roller parks must be available so that completely ground rollers are always available.
Um die Abkühlzeiten der Walzen zu verkürzen, hat man bereits Walzenkühleinrichtungen geschaffen, in denen die Walzen nach dem Ausbau aus den Walzgerüsten mit Wasser od. dgl. behandelt werden. Diese Einrichtungen sind aber sehr flächenintensiv und transportaufwendig und führen zu keinen zufriedenstellenden Ergebnissen.In order to shorten the cooling times of the rollers, roller cooling devices have already been created in where the rolls are treated with water or the like after they have been removed from the roll stands. However, these facilities are very space-intensive and transport-intensive and do not lead to satisfactory ones Results.
Aus der DE-AS 23 10 483 ist ein Verfahren und eine Vorrichtung zum Nachschleifen von Walzen bekannt, bei dem während des Schleifvorganges mittels differenzierter Kühlmittelzufuhr eine Vergleichmäßigung der Temperatur der Walze erreicht werden soll. Dieses Verfahren kann jedoch keine definierten Walzenprofile nach Beendigung des Schleifvorganges garantieren, da die Temperaturverteilung über die Walzenballenlänge nur geschätzt werden kann und nicht mit Sicherheit eine homogene Temperatur nach Schleifende vorliegt.From DE-AS 23 10 483 a method and a device for regrinding rollers is known, in which during the grinding process by means of a differentiated coolant supply an equalization of the Temperature of the roller should be reached. However, this method cannot have defined roll profiles after the end of the grinding process, guarantee that the temperature is distributed over the length of the roll barrel can only be estimated and a homogeneous temperature is not available with certainty after the end of the grinding process.
Von daher liegt der Erfindung die Aufgabe zugrunde, eine Steuereinrichtung der eingangs genannten Art zu schaffen, die ohne Vergleichmäßigung der temperaturThe invention is therefore based on the object of providing a control device of the type mentioned at the beginning create that without equalizing the temperature
ίο über die Ballenlänge der Wdze vor dem bzw. beim Nachschleifen auskommt, die außerdem den Walzenpark eines Flachwalzwerkes entscheidend verringert, ohne daß die notwendige Verfügbarkeit von fertig geschliffenen Walzen reduziert wird.ίο about the ball length of the root before or at Regrinding is sufficient, which also significantly reduces the number of rolls in a flat rolling mill, without reducing the necessary availability of completely ground rollers.
Nach der Erfindung wird die Aufgabe in der Weise gelöst, daß längs der Ballenlänge der Walze Temperaturfühler zum Messen der unterschiedlichen Walzentemperatur angeordnet sind, die zum Eingeben und Verarbeiten der Temperaturwerte an einen Rechner angeschlossen sind, durch den bei vorgegebenem Walzendurchmesser, Walzenmanterial und gewünschtem Schliff die Zustellung der Schleifscheibe steuerbar ist.According to the invention, the object is achieved in such a way that temperature sensors along the barrel length of the roller are arranged for measuring the different roller temperature, which are used for entering and Processing the temperature values are connected to a computer, through the given The infeed of the grinding wheel can be controlled by roll diameter, roll mantial and the desired grinding is.
Die Vorteile der Steuereinrichtung nach der Erfindung sind insbesondere darin zu sehen, daß sie keinerlei Wartezeiten zwischen Ausbau der Walze aus dem Walzgerüst und Schleifbeginn erfordert und einen genauen Walzenschliff bei beliebigem Temperaturprofil der Walze ermöglicht, wodurch der WalzenparkThe advantages of the control device according to the invention are particularly to be seen in the fact that they do not have any Waiting times between removing the roll from the roll stand and starting grinding requires and one enables precise roll grinding at any temperature profile of the roll, thereby reducing the number of rolls
mindestens um die Anzahl Walzen reduziert werden kann, die jeweils im Zwischenlager zum Zwecke des Temperaturausgleichs gelagert sind.can be reduced at least by the number of rollers that are in the intermediate storage for the purpose of Are stored temperature compensation.
Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert.The invention is explained in more detail below with reference to a drawing.
