Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Musterblechen aus Stahl, wie Riffel- oder Lupenblechen.The invention relates to a method for producing sample sheets of steel, such as corrugated or magnifying sheets.
Eine Einrichtung zur Herstellung eines Musterbleches mit einer Grunddicke von 2 mm und einer Musterhöhe von 2,5 mm ist aus der GB-A-4393 - A. D. 1893 bekannt. Zur Walzung von Musterblechen dieser Art sind schmale Walzgerüste vorgesehen, mit denen lediglich sehr schmale Musterbleche hergestellt werden konnten.A device for producing a sample sheet with a basic thickness of 2 mm and a sample height of 2.5 mm is known from GB-A-4393 - A.D. 1893. For rolling sample sheets of this type, narrow roll stands are provided, with which only very narrow sample sheets could be produced.
In heutiger Zeit werden Musterbleche zwecks Ermöglichung großer Breiten durch Warmwalzen von Breitband auf Breitbandstraßen hergestellt, wobei es bisher mit Schwierigkeiten verbunden bzw. ein ungelöstes Problem war, Musterbleche mit den eingangs beschriebenen Dimensionen herzustellen, denn es traten dabei Oberflächenfehler und Ungleichmäßigkeiten in der Musterhöhe, Verfestigungen und unerwünschte Markierungen, sog. »stretch marks«, auf. Es wurde auch das Auftreten von rauhen Kanten, Warzen u. dgl. beobachtet. Man ist daher dazu übergegangen, die Grunddicke des Bleches im Vergleich zur Musterhöhe relativ groß zu halten. Üblicherweise beträgt das Verhältnis der Grunddicke zur Musterhöhe mindestens 3 : 1, wobei als minimale Grunddicke 3 mm eingehalten wird. Solche Musterbleche haben ein verhältnismäßig hohes Gewicht und sind daher als Bekleidungselemente, z. B. für Lastkraftwagen, bisher nicht einzusetzen gewesen. Bei der Herstellung solcher Musterbleche ist im letzten Gerüst der Breitbandstraße eine Musterwalze als Oberwalze mit eingeschnittenem Muster eingebaut. Die Walzung dieser Musterbleche erfolgte bisher trocken, d. h. ohne Verwendung eines Schmiermittels.Nowadays, sample sheets are manufactured by hot-rolling broadband on broadband lines to enable large widths to be produced, although it has hitherto been difficult or an unsolved problem to produce sample sheets with the dimensions described at the outset, since surface defects and unevenness in the pattern height, hardening occurred and unwanted markings, so-called “stretch marks”. The appearance of rough edges, warts and the like. Like. observed. It has therefore started to keep the basic thickness of the sheet relatively large compared to the sample height. The ratio of the basic thickness to the sample height is usually at least 3: 1, whereby the minimum basic thickness is 3 mm. Such sample sheets have a relatively high weight and are therefore as clothing elements, for. B. for trucks, have not previously been used. In the production of such sample sheets, a sample roller as an upper roller with a cut pattern is installed in the last stand of the broadband mill. The rolling of these sample sheets has hitherto been carried out dry, i. H. without using a lubricant.
Die Erfindung stellt sich die Aufgabe, ein Verfahren der eingangs beschriebenen Art zur Herstellung von Musterblechen vor, leichtem Gewicht auf einer Breitbandstraße zu schaffen, bei dem die bisher auftretenden Schwierigkeiten und Nachteile, wie z. B. »stretch marks« und andere Oberflächenfehler, vermieden werden.The invention has for its object to provide a method of the type described above for the production of sample sheets, light weight on a broadband line, in which the difficulties and disadvantages previously encountered, such as. B. "stretch marks" and other surface defects can be avoided.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Einwalzung des Musters in das Blech unter Schmierung vorgenommen wird.This object is achieved in that the pattern is rolled into the sheet with lubrication.
Als Schmiermittel wird vorteilhaft eine Mischung von Schmieröl, Wasser und Dampf verwendet.A mixture of lubricating oil, water and steam is advantageously used as the lubricant.
Vorzugsweise wird das Verfahren derart ausgeübt, daß die im letzten Walzgerüst der Breitbandstraße als Oberwalze eingesetzte Musterrolle direkt, insbesondere durch Aufsprühen des Schmiermittels auf die Musterrollenoberfläche, geschmiert wird.The method is preferably carried out in such a way that the pattern roll used as the top roll in the last roll stand of the broadband mill is directly lubricated, in particular by spraying the lubricant onto the pattern roll surface.
Die Schmierung von Arbeitswalzen in einer Breitbandstraße durch indirekte Zuführung des Schmiermittels ist an sich bekannt (»Stahl und Eisen«, 92 [1972], Nr. 22, Seite 1115). Man hat diese Maßnahme für die ersten Gerüste vorgeschlagen, um Sekundärzundereinwalzungen zu vermeiden; doch hat sich diese Maßnahme kaum bewährt, weil durch die Zuführung des Schmiermittels beim Bandanstich Schwierigkeiten beim Greifen des Bandes aufgetreten sind. Bei der Schmierung gemäß der Erfindung besteht keine derartige Gefahr, da durch das Muster auf der Musterrolle ein einwandfreier Bandanstich auch bei Schmierung gewährleistet ist.The lubrication of work rolls in a broadband line by indirect supply of the lubricant is known per se ("Stahl und Eisen", 92 [1972], No. 22, page 1115). This measure has been proposed for the first stands in order to avoid secondary rolling in; however, this measure has hardly proven itself because the supply of the lubricant when tapping the tape caused difficulties in gripping the tape. With the lubrication according to the invention there is no such risk, since the pattern on the pattern roll ensures that the tape is tapped properly even when lubricated.
Das erfindungsgemäß hergestellte Blech ist in der Zeichnung näher erläutert, wobei die Fig. 1 und 1a ein Riffelblech und die Fig. und 2a ein Lupenblech, jeweils in Draufsicht und im Schnitt veranschaulichen.The sheet produced according to the invention is explained in more detail in the drawing, with FIGS. 1 and 1a illustrating a corrugated sheet and FIGS. And 2a illustrating a magnifying sheet, each in plan view and in section.
Aus den Fig. 1 und 1a ist ein Musterblech mit rautenartigen Erhebungen ersichtlich, deren Höhe (Musterhöhe) mit a bezeichnet ist. Die Grunddicke des Bleches ist mit b bezeichnet; b zu a stehen in dem oben angegebenen Verhältnis, u. zw. 1,3 : 1.1 and 1a a sample sheet with diamond-like elevations can be seen, the height (sample height) of which is denoted by a. The basic thickness of the sheet is designated by b; b to a are in the ratio given above, u. between 1.3: 1.
In gleicher Weise ist in den Fig. und 2a ein Lupenblech mit Lupenerhebungen dargestellt, wobei die Lupenhöhe mit a und die Grunddicke mit b bezeichnet ist. Auch hier wird das Verhältnis b zu a = 1,3 : 1 eingehaltenIn the same way, a magnifying glass sheet with magnifying glass elevations is shown in FIGS. And 2a, the magnifying glass height being designated a and the basic thickness being designated b. The ratio b to a = 1.3: 1 is also observed here
