Abstract

Process for rolling profiled rolling material comprises using a grooved roll which can be axially moved and consisting of a lower roll (UKW) which is pushed against the bearing surface of the upper roll (OKW). The stopping positions, length of movement and the calculated central positions are stored, and the course of the spring constant of the roll stand is calculated from these values and stored. An Independent claim is also included for a lower roll of the grooved roll comprising an axial bearing (AXU) having an outer ring connected to a cylinder piston arranged in a cylinder housing.

Description

Die Erfindung betrifft ein Verfahren zum Walzen von profiliertem Walzgut in Walzgerüsten mit Kaliberwalzenpaaren, deren Kaliber jeweils beidseitig von Anlaufbunden begrenzt sind (siehe z.B. die US-A-3 901 059).The invention relates to a method for rolling profiled rolling stock in roll stands with pairs of caliber rollers, the calibers of which are on both sides of start-up coils are limited (see e.g. US-A-3 901 059).

Beim Walzen von profiliertem Walzgut, wie Profil-Stählen, besonders solchen mit asymmetrischen Profilen, wie Z-Spundbohlen, Schienen, Relingeisen, Klemmplatten, Laufplatten, Hubmastschienen entstehen neben den vertikalen auch große axiale Walzkräfte, die je nach Profilart und Querschnittsgröße 1000 bis 2000 kN erreichen können. Diese axialen Walzkräfte verursachen ggfs. eine Verschiebung zwischen den Walzen, und der dadurch verursachte Querversatz der Walzkaliber führt zu fehlerhaften Profilen im Walzgut.When rolling profiled rolling stock, such as section steels, especially those with asymmetrical profiles, such as Z-sheet piles, rails, railing iron, clamping plates, Tread plates, mast rails are created in addition to the vertical also large ones axial rolling forces that, depending on the profile type and cross-sectional size, 1000 to 2000 can reach kN. These axial rolling forces may cause a shift between the rolls, and the resulting cross offset of the roll calibers leads to faulty profiles in the rolling stock.

Um diesen Querversatz zu vermeiden, hat man an beiden Seiten der Kaliber kreisringförmige Anlaufbunde mit steil geneigten, einander zugewandten Anlaufflächen zur Aufnahme dieser axialen Walzkräfte angeordnet Mit diesen wird beim Walzen ein geschlossener Kraftfluss zwischen beiden Walzen herbeigeführt. Diese Anordnung führt aber zu einem hohen Walzenverschleiß, hervorgerufen durch die Reibbewegungen zwischen den Kontaktflächen der oberen und unteren Anlaufbunde und erfordert zur Reduzierung des Verschleißes einen zusätzlichen hohen Aufwand an Schmiermitteln. Der trotz dieses Aufwandes nicht zu vermeidende Verschleiß an den Anlaufbunden macht es notwendig, die Walzen nach einem Einsatz mehr oder weniger stark abzuschleifen, damit für die steilen Anlaufbundseiten (etwa 87°) auch bei kleiner werdendem Durchmesser ihre funktionsgerecht gleiche axiale Position erhalten bleibt.In order to avoid this transverse offset, one has circular rings on both sides of the caliber Collars with steeply inclined, facing contact surfaces arranged to absorb these axial rolling forces a closed flow of force between the two rollers is brought about. This arrangement but leads to high roller wear caused by the rubbing movements between the contact surfaces of the upper and lower collars and requires additional effort to reduce wear of lubricants. The wear that cannot be avoided despite this effort on the start-up coils it is necessary to use the rollers after use grind to a greater or lesser extent so that for the steep sides of the collar (about 87 °) their functionally identical even with a decreasing diameter axial position is maintained.

Eine andere Möglichkeit zur Aufnahme der Axialkräfte besteht darin, anstelle der Anlaufbunde starke Drucklager zu verwenden, die die Axialkräfte über Halteelemente und den Ständer des Walzgerüstes aufnehmen. Dabei kommt es jedoch aufgrund großer elastischer Verformungen von z.B. 1 bis 4 mm pro 1000 kN je nach Baugröße und Walzgerüstform wegen der Vielzahl der an dem Kraftfluss beteiligten Bauelemente ebenfalls zu einem Querversatz der Kaliber der Walzen.Another way to absorb the axial forces is instead of Starting collars use strong thrust bearings that support the axial forces via holding elements and pick up the stand of the roll stand. But it does happen due to large elastic deformations of e.g. 1 to 4 mm per 1000 kN each by size and roll stand shape because of the variety of the power flow components involved also to offset the caliber of the rollers.

Wenn bestimmte Walzprofile aus walztechnologischen Gründen zwischen den einzelnen reversierenden Walzstichen jeweils um 180° gedreht werden müssen, führt dies zu einer entsprechenden Umkehr der Richtung der Axialkräfte mit der Folge einer Vergrößerung der Verschleißerscheinungen.If certain rolled sections between the individual reversing rolling passes must each be turned through 180 °, this leads to a corresponding reversal of the direction of the axial forces with the Result of an increase in the signs of wear.

Der Erfindung liegt die Aufgabe zugrunde, diese Verfahren zum Walzen profilierten Walzgutes mit Kaliberwalzen deren Kaliber beidseitig von Antaufbunden begrenzt sind, so zu verbessern, dass der Verschleiß an den Anlaufbunden wesentlich verringert und der Schmiermittelaufwand erheblich herabgesetzt werden.The invention is based, profiled these methods for rolling Rolled goods with caliber rolls, the caliber of which is bounded on both sides by tying-up are to be improved in such a way that wear on the starting collars is essential are reduced and the amount of lubricant is reduced considerably.

Diese Aufgabe wird dadurch gelöst, dass bei Verwendung mindestens einer Kaliberwalze, die axial positionsverschiebbar ist, diese Verschiebewalze unter definierter Last mit ihren Anlagebundflächen gegen die einen und die anderen Anlagebundflächen der anderen Walze verschoben, die Anschlagpositionen, die Länge des Verschiebeweges, die errechnete Mittenposition dieses Verschiebeweges gespeichert und die Verschiebewalze in eine kaliberfluchtende Position zu der anderen Walze gebracht wird, und dass die Verschiebewalze mit ihren Anlagebundflächen mit jeweils schrittweise definiert erhöhter Last gegen die eine und die andere Anlagebundfläche der anderen Walze verschoben, die Werte der jeweiligen Lasten, der Anschlagpositionen und der Verschiebewege gespeichert und aus diesen der Verlauf der Federkonstanten des Walzgerüstes errechnet und gespeichert wird, und dass die Verschiebewalze aus ihrer kaliberfluchtenden Position dann entgegen den während des Walzens zu erwartenden Axialkräften um einen, aus dem Verlauf der Federkonstanten errechneten Wert verschoben und während des Walzens in dieser Position über Positionsregeleinrichtungen gehalten wird.This object is achieved in that when using at least one caliber roller, which is axially position shiftable, this shift roller under defined Load with their investment areas against one and the other investment areas the other roller shifted, the stop positions, the length of the displacement path, the calculated center position of this displacement path is saved and the shift roller in one caliber aligned position to the other Roll is brought, and that the shift roller with its contact collar surfaces with incrementally defined loads against one and the other Contact surface of the other roller shifted, the values of the respective loads, the stop positions and the displacement paths saved and from these the course of the spring constants of the roll stand is calculated and saved and that the shift roller then out of its caliber-aligned position contrary to the axial forces to be expected during rolling the value of the spring constant and shifted during the Rolling is held in this position via position control devices.

Das erfindungsgemäße Verfahren bringt neben den oben erwähnten Möglichkeiten der Verschleißverringerung und der Schmiermitteleinsparung noch den weiteren sehr wesentlichen Vorteil mit sich, dass die beiden Kaliberwalzen während des Walzprozesses praktisch ständig in einer kaliberfluchtenden Position gehalten werden können und damit zu besonders guten Qualitäten von Profilprodukten führen, dies insbesondere auch dann, wenn das Walzen dieser Produkte ein Drehen des profilierten Walzstabes zwischen den Reversierstichen erfordert.In addition to the possibilities mentioned above, the method according to the invention brings the reduction in wear and the lubricant saving still another very important advantage that the two caliber rollers during the Rolling process kept practically constantly in a caliber aligned position can be and thus lead to particularly good qualities of profile products, this is particularly the case when the rolling of these products involves turning of the profiled roller rod between the reversing stitches.

AEU verbunden. In den Lagereinbaustücken LBO und LAO lagert mit ihren beiden Zapfen ZO eine obere Kaliberwalze OKW und in den Lagereinbaustücken LBO und LBU mit ihren Zapfen ZU eine untere Kaliberwalze UKW. Beide Kaliberwalzen OKW und UKW sind mit nebeneinander liegenden Kalibern OKL und OKR bzw. UKL und UKR ausgestattet.As can be seen from Fig. 1, the roll stand consists of a drive side Roller stand WSA and an operator-side roller stand WSB. In this are in the operator-side roll stand WSB bearing chocks LBO and LBU and in the drive-side roller stand WSA bearing chocks LAO and LAU guided vertically and connected to adjusting devices AEO and AEU, respectively.

Ein an dem Zylindergehäuse ZG angeordneter und mit dem Zylinderkolben ZK verbundener, mit einer nicht dargestellten Steuereinrichtung verbindbarer Weggeber WG erlaubt es, die Verschiebebewegungen des Zylinderkörpers ZK mit Hilfe der Hydrauliksteuerung zu steuern und damit entsprechende axiale Verschiebebewegungen des Zapfen ZU der unteren Kaliberwalze UKW hervorzurufen.A arranged on the cylinder housing ZG and with the cylinder piston ZK connected displacement sensor that can be connected to a control device, not shown WG allows the displacement movements of the cylinder body ZK with the help to control the hydraulic control and thus corresponding axial displacement movements of the pin TO cause the lower caliber roller FM.

Aus Fig. 3 geht hervor, dass die Kaliber KO der oberen Kaliberwalze OKW und die Kaliber KU der unteren Kaliberwalze UKW, die einen Walzspalt KWS für das Walzgut bilden, beidseitig steil verlaufende, jeweils einander zugewandte Anlagebundflächen AOL und AUL bzw. AOR und AUR aufweisen. Zwischen diesen werden in der dargestellten axialen Mittenposition der beiden Walzen gleich große Spalte SPL und SPR gebildet.3 shows that the caliber KO of the upper caliber roll OKW and the Caliber KU of the lower caliber roll FM, which has a roll gap KWS for the Form rolling stock, steep faces on both sides, each facing the other AOL and AUL or AOR and AUR. Between these will be in the illustrated axial center position of the two rollers of the same size Column SPL and SPR formed.

Aus den Fig. 4 und 5 gehen die Positionen der unteren Kaliberwalze UKW bei der Verschiebung mit Hilfe des im Zylindergehäuse ZG verschiebbaren Zylinderkolbens (Fig. 2) und der diesen steuernden Einrichtungen hervor. Die untere Kaliberwalze UKW liegt, in Richtung des Pfeils PR nach rechts bewegt (Fig. 4) unter dem vorgegebenen Druck mit ihrer Anlagebundfläche AUL an der Anlagebundfläche AOL der oberen Kaliberwalze OKW an. Anschließend wird sie in Richtung des Pfeils PL nach links bewegt ( Fig. 5), unter dem gleichen Druck mit ihrer Anlagebundfläche AUR an der Anlagebundfläche AOR der oberen Kaliberwalze OKW an, wobei neben der Größe des Andruck-Drucks auch der Verschiebeweg gemessen und gespeichert werden. Auf die gleiche Weise werden die schrittweise erhöhten Andruckdrucke und die aus diesen resultierenden größeren Verschiebewege ermittelt und gespeichert.4 and 5, the positions of the lower caliber roller FM at Displacement with the aid of the cylinder piston which can be moved in the cylinder housing ZG (Fig. 2) and the controlling these devices.
