Abstract

A method of X-H rolling of a parallel flange steel structural shape or beam with an H cross section using a compact rolling group. In the first universal mill frame the vertical roll have roll surfaces inclined to one another at an angle up to 10° whereas in the second universal mill frame the vertical rolls have cylindrical roll surfaces which divide the H opening cross section with lateral surfaces of the horizontal roll. The structural shape is rolled in the second universal mill frame to up to 100% of the reduction in the first rolling mill frame.

Description

Die Erfindung bezieht sich auf ein Arbeitsverfahren zum XH-Walzen von parallelflanschigen Stahlprofilen (-Trägem) mit H-Profil im Tandembetrieb in einer Kompaktwalzgruppe, die aus einem ersten Universalgerüst, einem diesem nachgeordneten Stauchgerüst und einem folgenden, zweiten Universalgerüst besteht, wobei die Walzen der Gerüste geneigt, bzw. vertikal zu den Achsen der Walzen verlaufende Walzflächen aufweisen.The invention relates to a working method for XH rolling of parallel-flanged steel profiles (trusses) with H-profile in tandem operation in one Compact rolling group consisting of a first universal scaffolding, this one downstream upsetting frame and a following, second universal frame consists, with the rollers of the frameworks inclined, respectively vertical to the axes of the Rolls extending rolling surfaces.

Als Rohmaterial für den Anstich in dieser Kompaktwalzgruppe wird entweder vorgewalztes Stranggußmaterial verwendet, wobei die Vorwalzungen auf einem konventionellen Breakdown-Gerüst oder aber in einer Vertikal-Horizontal-Reversierwalzgruppe bzw. einer Horizontal-Universal bzw. Vertikal-Horizontal-Universal-Reversierwalzgruppe erfolgen. Es können aber auch endabmessungsnahe stranggegossene Vorprofile dieser Kompaktwalzgruppe zugeführt werden.As raw material for the tapping in this compact rolling group is either pre-rolled continuous casting material used, the Vorwalzungen on a conventional breakdown stand or in a vertical-horizontal Reversierwalzgruppe or a horizontal universal or vertical horizontal universal Reversierwalzgruppe respectively. But it can also near-net-shape continuous cast pre-profiles of this compact rolling group be supplied.

Beim Walzen dieser H.-Profile nach diesem Arbeitsverfahren ergeben sich insb. bei schweren Trägem Nachteile eines großen und darüber hinaus in dem einen, gegenüber dem anderen Horizontalgerüst unterschiedlichen Verschleißes der Walzenflächen insb. der, der Horizontalwalzen. Dieser Verschleiß führt dazu, dass die Walzen häufig neu abgedreht werden müssen und damit zu einer erheblichen Erhöhung der Betriebskosten.When rolling these H. profiles according to this procedure, esp. At heavy wearers cons of a great and beyond in the one, compared to the other horizontal frame different wear of the Roller surfaces esp., The horizontal rollers. This wear causes that The rollers often have to be re-twisted and thus to a considerable Increase in operating costs.

Erfahrungen haben dabei gezeigt, dass es zweckmäßig ist, den Verschleiß der Horizontalwalzen im ersten Universalgerüst und den Verschleiß der Horizontalwalzen im zweiten Universalgerüst möglichst gleich zu halten, um dieses Nachdrehen der beiden Horizontalwalzensätze zu einem möglichst kostengünstigen Zeitpunkt gleichzeitig durchzuführen, um beim Abstimmen der Ballenbreite der beiden Walzensätze zueinander einen unnötig großen Materialverlust zu vermeiden. Diese Abstimmung des Verschleißverhaltens hat sich aber in der Praxis als sehr schwierig erwiesen.Experience has shown that it is appropriate to wear the Horizontal rolls in the first universal stand and the wear of the Horizontal rolls in the second universal stand as equal as possible to keep this Turning the two horizontal roller sets to a cost as possible Time to perform at the same time to adjust the bale width of the Both sets of rolls to each other to avoid an unnecessarily large loss of material. This tuning of the wear behavior has in practice as a lot difficult to prove.

Der Erfindung liegt die Aufgabe zugrunde, den Verschleiß der Horizontalwalzen zu verringern, für beide Gerüste aufeinander abzustimmen und möglichst gleich zu halten.The invention is based on the object, the wear of the horizontal rollers reduce, for both scaffolds to coordinate and as equal as possible hold.

Diese Aufgabe wird dadurch gelöst, dass bei Verwendung von Vertikalwalzen mit, zwischen 0 Grad und 10 Grad voneinander weg geneigten Walzflächen im ersten Universalgerüst und von Vertikalwalzen mit zylindrischen Walzflächen im zweiten Universalgerüst, die Seitenflächen der Horizontalwalzen, die mit den Walzenflächen der Vertikalwalzen das H-Kaliber bilden, Neigungen von 0,0 Grad bis 0,5 Grad aufweisen und in dem zweiten Universalgerüst jeweils eine Reduktion des Walzgutes zu bewirken, die 0 - 100% der im ersten Universalgerüst erzielten Abnahme beträgt.This object is achieved in that when using vertical rollers with, between 0 degrees and 10 degrees away from each other inclined rolling surfaces in the first Universal scaffolding and vertical rolls with cylindrical rolling surfaces in the second Universal scaffolding, the side surfaces of the horizontal rolls, with the roll surfaces the vertical rolls form the H caliber, slopes of 0.0 degrees to 0.5 degrees in each case in the second universal stand a reduction of To produce rolling stock, the 0 - 100% of the achieved in the first universal scaffolding Decrease is.

Die äußere Ballenlänge der Horizontalwalzen des zweiten Universalgerüstes kann dabei vorteilhaft dem Kammerinnenmaß des zu walzenden H-Trägers entsprechen.The outer bale length of the horizontal rollers of the second universal stand can thereby advantageously correspond to the chamber internal dimension of the H-beam to be rolled.

im Normalfall könnte man bei der Anwendung des Arbeitsverfahrens die Abnahmen von 100% der Abnahme im ersten Universalgerüst in den Folgestichen kaskadenförmig bis zum letzten Stich mit minimal 5% wählen. Es kann aber auch von Vorteil sein, aus Gründen der Temperaturverhältnisse einen Durchgang mit sehr geringer Abnahme in den beiden Universalgerüsten zu fahren, um dann die Abnahme in den Gerüsten anschließend wieder zu erhöhen.Normally, the use of the work procedure could be reduced of 100% of the decrease in the first universal scaffold in the following passes cascade to the last stitch with a minimum of 5%. But it can too be beneficial, for reasons of temperature conditions a passage with very to drive a small decrease in the two universal scaffolding, then the Decrease in scaffolding then increase again.

Die Anwendung des erfindungsgemäßen Arbeitsverfahrens erlaubt es, für das notwendige Nachdrehen der Walzen beider Universaigerüste einen gleichzeitigen und damit kostengünstigen Zeitpunkt zu ermitteln und durch diese Abstimmung auch die Materialverluste und somit die gesamten Fertigungskosten zu senken.The application of the working method according to the invention makes it possible for the necessary rewinding of the rolls of both Universaigerüste a simultaneous and thus cost-effective time to determine and by this vote also to reduce the material losses and thus the total production costs.

Claims (2)
