Description
Einrichtung zum Kühlen der Walzen eines Walzwerkes zum Herstellen von Bändern, Blechen, Drähten, Stangen, Profilen od. dgl. aus grob- oder feinstöckigem Metall Es ist bekannt, aus Pulver oder grobstöckigem Material, insbesondere aus Metallen,. kompakte Bänder durch Walzen herzustellen.Device for cooling the rolls of a rolling mill for manufacturing of strips, sheets, wires, rods, profiles or the like made of coarse or fine-grained material Metal It is known to be made from powder or coarse material, in particular from Metals ,. to produce compact strips by rolling.
Die beim Kaltwalzen auftretende Erwärmung der Walzen läßt sich in der Regel durch eine Innenkühlung in erträglichen Grenzen halten. Beim Warmwalzen reicht diese Kühlung in der Regel jedoch nicht mehr aus.The warming of the rolls that occurs during cold rolling can be seen in usually keep them within tolerable limits by internal cooling. When hot rolling However, this cooling is usually no longer sufficient.
Beim Warmwalzen von kompakten Metallen erzielt man daher eine Walzenkühlung durch Aufspritzen der Kühlflüssigkeit auf die Oberflächen der Walzen.Roll cooling is therefore achieved when hot rolling compact metals by spraying the cooling liquid onto the surfaces of the rollers.
Umgekehrt sollen die Walzen in der Regel nicht zu kalt sein, um ein zu starkes Abkühlen des Walzgutes im Walzspalt zu vermeiden. Insbesondere nach längeren Stillstandszeiten des Walzwerkes besteht die Möglichkeit, die Walzen durch Besprühen mit einer erwärmten Flüssigkeit, durch Glühhauben usw. zu temperieren. In vielen Fällen hat dabei die Flüssigkeit zugleich die Aufgabe, einen Schmierfilm zwischen Walze und Walzgut zu bringen, sei es, um die Reibungsverluste zu verringern oder gar ein Festkleben von Teilen des Walzgutes als Flitter an den Walzen zu vermeiden.Conversely, the rollers should not usually be too cold to get one to avoid excessive cooling of the rolling stock in the roll gap. Especially after longer When the rolling mill is idle, there is the possibility of spraying the rollers to regulate the temperature with a heated liquid, by means of annealing hoods, etc. In many Cases, the liquid also has the task of creating a lubricating film between Bringing the roll and rolling stock, be it to reduce the friction losses or even to avoid parts of the rolling stock sticking to the rollers as tinsel.
Wendet man dieses Verfahren auf das Walzen von nicht kompakten Metallen an, so besteht die Gefahr, daß das Mittel zum Kühlen oder Erwärmen der Walzen zwischen die Partikeln des Walzgutes oder in die Poren des noch nicht voll verdichteten Walzgutes gelangt. Je nach Art des Mittels würde damit eine enge Verbindung der Partikeln verhindert oder erschwert.If one applies this process to the rolling of non-compact metals on, there is a risk that the means for cooling or heating the rollers between the particles of the rolling stock or in the pores of the not yet fully compacted rolling stock got. Depending on the type of agent, this would create a close connection between the particles prevented or made difficult.
Der Erfindung liegt die Aufgabe zugrunde, eine intensive Kühlung der Walzenoberfläche zu erreichen, wobei eine Berührung des Kühlmittels mit dem zu walzenden Metall ausgeschlossen ist.The invention is based on the object of intensive cooling of the To achieve roll surface, with a contact of the coolant with the to be rolled Metal is excluded.
Zur Lösung der Aufgabe ist eine Vorrichtung zum Zwecke der Walzgutzuführung richtungsweisend, wobei eine Walze, gegebenenfalls auch beide Walzen, von je einem endlosen Band, insbesondere Stahlband, umschlungen werden und jedes Band von einer Rolle oder auch mehreren Rollen umgelenkt und gespannt wird.To achieve the object is a device for the purpose of the rolling stock supply pointing the way, with one roller, optionally also both rollers, of one each endless belt, in particular steel belt, are wrapped around and each belt by one Roll or several rolls is deflected and tensioned.
Die Erfindung besteht darin, daß jede Walze in bekannter Weise im Einzugsbereich für das Walzgut und im Walzspalt von einem endlosen Band umschlungen ist, das durch eine im Abstand von der Walze angeordnete Umlenkrolle gespannt ist, und daß in dem von dem Band nicht umschlungenen Bereich der Walzenoberfläche gleichfalls bekannte, ein Kühlmittel an die Walzen abgebende Sprühdüsen angeordnet sind. Damit wird mit Sicherheit verhindert, daß das Kühlmittel mit dem Walzgut in Berührung kommt, und zugleich eine intensive Kühlung der Walzenoberflächen und damit auch der Stahlbänder geschaffen.The invention consists in that each roller in a known manner in Infeed area for the rolling stock and wrapped in an endless belt in the roll gap which is tensioned by a deflection roller arranged at a distance from the roller, and that in the area of the roller surface which is not wrapped by the belt as well known, a coolant to the rollers dispensing spray nozzles are arranged. In order to the coolant is definitely prevented from coming into contact with the rolling stock comes, and at the same time an intensive cooling of the roll surfaces and thus also created of steel belts.
Die Erfindung wird an Hand der Zeichnung, die ein Ausführungsbeispiel in schematischer Darstellung zeigt, beschrieben: Mit 1 ist eine obere Walze und mit 2 eine untere Walze bezeichnet. Beide Walzen werden über ein bekanntes, nicht dargestelltes Kammwalzengetriebe angetrieben. Um die obere Walze 1 ist ein endloses Band 3, um die untere Walze 2 ein endloses Band 4 geschlungen. Mit 5 ist ein Metallpulver bezeichnet, welches von den Bändern 3 und 4 erfaßt wird und durch den Walzdruck der Walzen 1 und 2 zu einem Band, Profil 0d. dgl. ausgewalzt wird. Beide Bänder 3 und 4 werden von Rollen 6 und 7 umgelenkt und gespannt. Sprühdüsen 8 und 9 besprühen die Walzen 1 und 2 mit Kühlmittel. Mit 10 ist ein Abführrollgang für das gewalzte Band, Profil od. dgl. bezeichnet.The invention is based on the drawing, which shows an embodiment shows in a schematic representation, described: With 1 is an upper roller and with 2 denotes a lower roller. Both reels are known about a not illustrated pinion gear driven. Around the top roller 1 is an endless one Belt 3, around the lower roller 2 an endless belt 4 is looped. With 5 is a metal powder denotes which is caught by the belts 3 and 4 and by the rolling pressure of rollers 1 and 2 to form a strip, profile 0d. Like. Is rolled out. Both bands 3 and 4 are deflected and tensioned by rollers 6 and 7. Spray nozzles 8 and 9 rolls 1 and 2 with coolant. At 10 there is a discharge roller table for the rolled Band, profile or the like. Designated.
