Description

Gegenstand der vorliegenden Erfindung ist ein Kompaktwalzblock mit zwei parallelen Linien, insbesondere für Drähte, in Übereinstimmung mit den allgemeinen Merkmalen des Anspruchs 1.The present invention relates to a compact rolling block with two parallel lines, especially for Wires, in accordance with the general characteristics of claim 1.

Technischer BereichTechnical part

Der Block wird auch in einem Heißwalzwerk zur Parallel-Simultanfließerzeugung von Mehrfachdraht, auch unmittelbar verbunden mit einer in Linie befindlichen Stranggußanlage angewendet.The block is also used in a hot rolling mill for parallel simultaneous flow generation of multi-wire, also immediately connected to a continuous casting plant in line applied.

Ältere TechnikOlder technology

Dem derzeitigen Stand der Technik entsprechend sind verschiedene Produktionsmethoden für den Strangguß und das Heißwalzen bekannt, die meistverwendete betrifft den Guß und das Fließwalzen von Knüppeln , die nach und nach dünner gewalzt werden, bis die Stange oder der Metalldraht den gewünschten endgültigen Querschnitt erreicht hat. Are in accordance with the current state of the art different production methods for continuous casting and that Hot rolling is known, the most common is cast and the flow rolling of billets that are gradually thinning be rolled until the rod or metal wire has reached the desired final cross section.

Bei kleinen Querschnitten versteht es sich, daß die Arbeit sehr kostenintensiv wird, sowohl aufgrund der Arbeitszeit als auch wegen der Kompliziertheit und der Kosten, so daß zur Gewährleistung der Produktivität die Walzgeschwindigkeit ständig und kontinuierlich erhöht werden muß, wobei der Wert von 100 m/sek. bei gespultem Metalldraht bei weitem überschritten wird.With small cross sections, it is understood that the work becomes very costly, both because of the working hours as well as the complexity and cost, so that the rolling speed to ensure productivity must be increased continuously and continuously, whereby the value of 100 m / sec. with coiled metal wire is exceeded by far.

Derzeit wird das Splitwalzverfahren angewendet.The split rolling process is currently used.

Diese Lösung besteht in der Herstellung von zwei Stangen aus einer vorhergehenden Bearbeitung unter Walzen des Knüppels zur Anfertigung von Walzmaterial von zunehmend geringerem Querschnitt zum Zwecke der Trennung des in zwei Stangen vorgeschobenen Walzmaterials, das um 90° gedreht und bis zur endgültigen Stärke weiter gewalzt wird (JP-A-60-130401).This solution consists in the production of two bars from a previous processing under rolling the Billets for the production of rolling stock from increasing smaller cross section for the purpose of separating the two Rods of advanced rolling stock rotated 90 ° and rolling to the final thickness (JP-A-60-130401).

Vom gleichen Knüppel ausgehend ist es auch möglich, 4 Stahlstangen mit zwei hintereinander erfolgenden, auf derselben Walzunterlage erfolgenden Splits herzustellen.Starting from the same stick, it is also possible to 4 Steel bars with two successive, on to produce the same rolling stock splits.

Dieses Verfahren beginnt mit einem Knüppel (z.B. 160 x 160 mm), der aus einem Wärmeofen mit einer Stundenproduktion von beispielsweise 37 Tonnen/h stammt.This process starts with a stick (e.g. 160 x 160 mm) from a heating furnace with an hourly production of, for example, 37 tons / h.

Es können auch vorgeschaltete, auch horizontal angeordnete Spulmaschinen z.B. des Typs "EDEMBOR" für Metalldraht mit einem Durchmesser von < 5,5 mm unter Verwendung mehrerer Linien vorgesehen sein.Upstream, even horizontally arranged ones can also be used Winding machines e.g. type "EDEMBOR" for metal wire with a diameter of <5.5 mm using several Lines can be provided.

Die Verwendung von mehreren Linien erhöhen jedoch die Kompliziertheit und die Ausmaße der Anlage.However, using multiple lines increases the Complexity and size of the facility.

Zweck der vorliegenden Erfindung ist es, die Leistungen zu verbessern und die Ausmaße der Walzlinien, insbesondere der Drahtwalzlinien, auf ein Minimum zu begrenzen und gleichzeitig die Struktur des Walzblockes so weit wie möglich zu vereinfachen.The purpose of the present invention is to achieve the benefits improve and the dimensions of the rolling lines, especially the Wire rolling lines to be kept to a minimum and at the same time the structure of the rolling block as far as possible to simplify.

Wie beansprucht, umfaßt der Kompaktwalzblock zwei horizontale, parallele Walzlinien (L1, L2) mit drei peripheren Übertragungsachsen (2, 3, 4) an den Spitzen eines gleichschenkligen Dreiecks, in welchem die beiden unteren peripheren Achsen (3, 4) vertikale Gerüste bewegen, die nach außen geneigt sind (VL, VR) und die obere periphere Achse horizontale Gerüste trägt, die entgegengesetzt geneigt sind (OL, OR), deren Rollen allesamt rechtwinklig denkungsgleich mit den besagten zwei Walzlinien (L1, L2) sind.As claimed, the compact roll block comprises two horizontal, parallel rolling lines (L1, L2) with three peripheral transmission axes (2, 3, 4) at the tips an isosceles triangle in which the two lower peripheral axes (3, 4) move vertical frameworks, which are inclined outwards (VL, VR) and the upper one peripheral axis carries horizontal scaffolds that are oppositely inclined (OL, OR), their roles all at right angles to the two in question Rolling lines (L1, L2) are.

Wie aus den oben angesprochenen Abbildungen hervorgeht, umfaßt der Walzblock insbesondere:

  • einen einzelnen Motor (M) mit einer einzelnen Motorachse (1), welche die Bewegung mittels eines Zahnradgetriebes (11) auf drei Zahnräder überträgt, die in Form eines gleichschenkligen Dreiecks (21, 31, 41) radial angeordnet und jeweils mit peripheren Übertragungswellen (2, 3, 4) ausgestattet sind, auf welchen jeweils ein Walzgerüst (OR, VR, VL) angestiftet ist, wobei ein jedes Walzgerüst mit einem Kopfwalzrollenpaar (RR) versehen ist, welches die Rotationsübertragung mittels eines konischen Vorgeleges (c1) und die Zwischenübertragung (c2) von den besagten peripheren Übertragungswellen (2, 3, 4) empfängt;
  • wobei zwei der besagten peripheren Wellen sich als periphere Basiswellen (3, 4) auf der Höhe unterhalb der Basiswinkel des besagten gleichschenkligen Dreiecks befinden und die dritte Welle sich als obere periphere Welle (2) an der oberen Spitze des besagten gleichschenkligen Dreiecks befindet, wobei
  • die beiden peripheren Basiswellen (3, 4) die jeweiligen Walzgerüste auf der rechten und der linken Seite (VR, VL) mit den Walzrollenpaaren (RR) für vertikales Walzen nach rechts und nach links (VRR) nach oben bewegen;
  • die besagte obere Welle (2) alternativ ein Gerüst nach rechts (OR) und ein Gerüst nach links (OL) mit dem entsprechenden Kopfrollenpaar (RR) für horizontales Walzen (ORR) unterstützt, wobei
  • die Positionierung der besagten peripheren Wellen (2, 3, 4), die Neigung und die Ausmaße der besagten Walzgerüste (OR, VL, VR) sowie die Position der entsprechenden Walzrollenpaare (RR) so ausgelegt ist, daß die jeweiligen Walzkanäle aller besagter Walzrollen (RR) auf zwei Längswalzlinien (L1, L2) zusammentreffen, die von einer Seite zur anderen symmetrisch, jeweils oberhalb der besagten peripheren Basiswellen (3, 4) und unterhalb sowie seitlich der besagten peripheren oberen Welle (2) verlaufen unter abwechselnder Anordnung von vertikalen Gerüsten und Walzrollen (VL/VR-VRR) und horizontalen Gerüsten und Walzrollen (OL/OR-ORR), wobei der Wechsel von einem horizontalen, rechten Walzgerüst (OR-ORR) bestimmt wird, das im Wechsel mit einem linken horizontalen Walzgerüst (OL-ORR) agiert, wobei vorgesehen ist, daß auf der gegenüberliegenden Seite ein entsprechendes vertikales Walzgerüst, jeweils links (VL-VRR) und rechts (VR-VRR) in etwa auf derselben Höhe eintritt.
As can be seen from the figures mentioned above, the rolling block includes in particular:
  • a single motor (M) with a single motor axis (1) which transmits the movement by means of a gear transmission (11) to three gears, which are arranged radially in the form of an isosceles triangle (21, 31, 41) and each with peripheral transmission shafts (2 , 3, 4), on each of which a roll stand (OR, VR, VL) is pinned, each roll stand being provided with a pair of head rolls (RR) which transmit the rotation by means of a conical gear (c1) and the intermediate transfer ( c2) from said peripheral transmission waves (2, 3, 4);
  • wherein two of said peripheral waves are peripheral peripheral waves (3, 4) at the level below the base angles of said isosceles triangle and the third wave is upper peripheral waves (2) at the top of said isosceles triangle, wherein
  • the two peripheral base shafts (3, 4) move the respective roll stands on the right and left side (VR, VL) with the roller pairs (RR) for vertical rolling to the right and to the left (VRR) upwards;
  • said upper shaft (2) alternatively supports a stand to the right (OR) and a stand to the left (OL) with the corresponding head roller pair (RR) for horizontal rolling (ORR), whereby
  • the positioning of said peripheral shafts (2, 3, 4), the inclination and the dimensions of said roll stands (OR, VL, VR) and the position of the corresponding pairs of rolls (RR) are designed so that the respective rolling channels of all said rolls ( RR) meet on two longitudinal rolling lines (L1, L2), which run symmetrically from one side to the other, each above the said peripheral basic shafts (3, 4) and below and to the side of the said peripheral upper shaft (2) with an alternating arrangement of vertical stands and rolling rolls (VL / VR-VRR) and horizontal stands and rolling rolls (OL / OR-ORR), the change being determined by a horizontal, right rolling stand (OR-ORR), which alternates with a left horizontal rolling stand (OL- ORR) acts, whereby it is provided that a corresponding vertical roll stand, on the left (VL-VRR) and right (VR-VRR), enters at approximately the same height on the opposite side.

Wie man ersehen kann, wird der Walzblock auf diese Weise stark kompaktiert und besitzt die gleiche Anzahl von vertikalen Walzgerüsten (im dargestellten Fall: drei) auf der rechten (VR) und der linken (VL) Seite bei den beiden unteren, peripheren Wellen (3, 4), während 2xn Walzgerüste auf die obere Welle (2) jeweils zur Hälfte auf der linken (OL) und zur Hälfte auf der rechten (R) Seite aufgepreßt sind, die im wesentlichen beide gleich aufgebaut sind. As can be seen, the billet is made this way highly compact and has the same number of vertical rolling stands (in the illustrated case: three) the right (VR) and the left (VL) side of the two lower, peripheral shafts (3, 4), while 2xn mill stands on the upper shaft (2) half on the left (OL) and half pressed on the right (R) side are, which are both essentially constructed the same.

Auf diese Weise wird verständlich, daß auch die Produktionskosten des gesamten Walzblockes stark vermindert, die Probleme im Zusammenhang mit Wartung und Ersatzteilaustausch vereinfacht und nicht nur die Walzrollenpaare, sondern auch die einzelnen Walzgerüste leicht ersetzt werden können, da sie allesamt gleich sind.In this way it is understandable that the Production costs of the entire billet greatly reduced, the problems related to maintenance and Replacement parts simplified and not just that Pairs of rolls, but also the individual roll stands can be easily replaced as they are all the same.

Die besagten drei peripheren Übertragungswellen (2, 3, 4), zusammen mit den besagten zwei Wellen oder Walzlinien (L1, L2) bilden im vertikalen Querschnitt eine Struktur in der Form der Spitzen eines gleichschenkligen Fünfecks.Said three peripheral transmission waves (2, 3, 4), together with said two shafts or rolling lines (L1, L2) form a structure in the vertical cross section Shape of the tips of an isosceles pentagon.
