Description

KAISERLICHESIMPERIAL

PATENTAMT.Y&PATENTAMT.Y &

Vorliegende Erfindung stellt ein Verfahren und die zur Ausführung desselben dienende Vorrichtung zum Dünnwalzen von Blechen dar und bezweckt vor allem, Bleche von beliebiger Feinheit und beliebiger Länge herzustellen. The present invention provides a method and the one for carrying out the same Device for the thin rolling of sheet metal and aims above all to sheet metal of any To produce delicacy and any length.

Dies war nach dem bisherigen Walzverfahren insofern unmöglich, weil das Dünnwalzen der Bleche von einer gewissen Stärke ab aus ver- (j schiedenen Gründen, namentlich zur Vermeidung von allzugrofsen Wärmeverlusten und Verlusten durch Bildung von Zunder, in Packeten vor sich gehen mufste. Uebermäfsige Wärmeverluste, sowie Zunderbildung vermindert Erfinder nun dadurch, dafs er das Blech, sobald es nach dem gewöhnlichen Verfahren auf einem Triowalzwerk bis zu einer gewissen Stärke herabgewalzt ist, auf eine Rolle aufwickelt. - In diesem Zustande wird es abermals geglüht, M wobei ein Aufwickeln der Rolle durch umgelegte belastete Ketten oder dergl. vermieden wird. Das Glühen kann in einem gewöhnlichen Ofen geschehen, worauf es in eine Schutzkappe A eingehängt und dicht vor das Walzwerk gefahren wird. Die Schutzkappe kann selbst erwärmt sein, oder aber es kann der ganze Ofen vor das Walzwerk gefahren werden. Die Rolle ist in der Hülle A drehbar gelagert, so dafs die Walzen, wenn einmal das vordere Ende erfafst ist, das Blech selbstthätig dem Verbrauch entsprechend von der Rolle abwickeln und es durch den in dem unteren Theil der Klappe oder Ofen vorgesehenen Schlitz herausziehen.This was so far impossible after the previous rolling process because the thin rolls of sheets of a certain strength from from comparable (j various reasons, notably to avoid allzugrofsen heat losses and losses due to formation of scale in Packeten proceed was obliged. Uebermäfsige heat losses, and the formation of scale is now reduced by the inventor by winding the sheet onto a roll as soon as it has been rolled down to a certain thickness on a trio rolling mill by the usual method The annealing can be done in an ordinary furnace, whereupon it is hung in a protective cap A and moved close to the rolling mill. The protective cap itself can be heated, or the entire furnace can be in front of the rolling mill The roller is rotatably mounted in the casing A , so that the rollers, once the v at the lower end, unwind the sheet automatically from the roll as it is used up and pull it out through the slot provided in the lower part of the flap or oven.

Das Walzwerk besteht aus zwei dünnen Arbeitswalzen I, sowie aus vier Abstützwalzen II. Die untere Walze I, sowie deren beide Abstützwalzen sind beiderseitig in einem im Walzenstuhl geführten Kopf gelagert, der durch einen Kolben K getragen wird. Jeder dieser Kolben K pafst in einen Cylinder, welcher während des Walzens mit dem Wasser eines Accumulators in Verbindung gesetzt wird. Diese Anordnung ist -zur Ausführung des neuen Verfahrens von grofser Wichtigkeit, da durch sie die Dicke des zu walzenden Bleches nicht durch starr eingestellte Druckschrauben bestimmt wird, sondern das Resultat einer Pressung ist, die einerseits durch die Gröfse des hydraulischen Druckes und andererseits durch die Weichheit des Walzgutes bestimmt ist. /Das aus den Walzen austretende Blech wird sofort wieder zu einer Rolle aufgewickelt, um schädliche Zunderbildung zu vermeiden und um eventuell abermals geglüht und ausgewalzt zu werden.'·,The rolling mill consists of two thin work rolls I and four support rolls II. The lower roll I and its two support rolls are mounted on both sides in a head guided in the roll frame and carried by a piston K. Each of these pistons K fits in a cylinder which is placed in contact with the water of an accumulator during rolling. This arrangement is of great importance for the execution of the new process, since it does not determine the thickness of the sheet to be rolled by rigidly set pressure screws, but is the result of a pressure which is determined on the one hand by the magnitude of the hydraulic pressure and on the other hand by the softness of the rolling stock is determined. / The sheet metal emerging from the rollers is immediately rewound into a roll in order to avoid harmful scale formation and to possibly be annealed and rolled out again. '·,

Das Aufwickeln geschieht selbstthätig auf eine Walze C, die in einem Gestell B so gelagert ist, dafs sie sich dem Dickwerden der Rolle entsprechend vertical verrücken kann; sie ruht auf zwei Walzen α und b, welche auf passende Weise in Umdrehung gesetzt werden, so dafs sie die Rolle fortwährend zu drehen bestrebt ist. Die Rolle wird durch einen Hebel (H) belastet. Damit sich das aus der Walze kommende Blech sofort um die Walze C herumlegen kann, ist in dem Bocke B ein Hebel </ gelagert, welcher die Walze C theilweise umfafst und in welchen kleineThe winding takes place automatically on a roller C, which is mounted in a frame B in such a way that it can move vertically as the roll becomes thick; it rests on two rollers α and b, which are set in rotation in a suitable manner, so that it tends to keep turning the roller. The roller is loaded by a lever (H). So that the sheet metal coming out of the roller can immediately lie around the roller C, a lever is mounted in the bracket B , which partially embraces the roller C and in which small ones

Rollen (r) gelagert sind. Sobald das Blech sich einmal um die Walze C herumgewickelt hat, kann der Hebel J herumgeklappt werden, da nunmehr das weitere Aufwickeln ohne Weiteres in dem Mafse der Blecherzeugung vor sich geht.Rollers (r) are stored. As soon as the sheet has wrapped itself around the roller C , the lever J can be swung around, since the further winding can now easily be carried out in proportion to the sheet production.

Patent-Ansprüche:Patent Claims: i. Verfahren zum Glühen und Auswalzen dünner langer Bleche, dadurch gekennzeichnet, dafs das Blech in zusammengerolltem Zustande geglüht und dann direct oder nach Unterbringung unter eine Schutzkappe A zwischen die Walzen geführt wird, wobei ein Aufrollen des Bleches im Ofen oder unter der Schutzkappe A stattfindet. Zur Ausführung des Verfahrens nach Anspruch ι eine Wickelvorrichtung, bestehend aus drei sich drehenden Walzen abc, von welchen die das Blech aufwickelnde Walze belastet ist und in diese Walze eine abklappbare Führung greift, welche das Umlegen der ersten Wickelung bewirkt.i. Process for annealing and rolling thin long sheets, characterized in that the sheet is annealed in the rolled-up state and then passed between the rollers either directly or after being placed under a protective cap A , the sheet being rolled up in the furnace or under the protective cap A. To carry out the method according to claim ι a winding device consisting of three rotating rollers abc, from which the roller winding the sheet is loaded and a foldable guide engages in this roller, which causes the first winding to be turned over.
