"Verfahren zum Walzen von Zinkblöcken11 "Method of Rolling Zinc Ingots 11
Die vorliegende Erfindung betrifftjein Verfahren"zum Walzen von Blöcken aus Zink oder Zinklegierung.The present invention relates to each method "for rolling Zinc or zinc alloy blocks.
Bei der bekannten Technik des Walzens von Blöcken aus Zink oder Zinklegierung wird der Block zwischen Walzen eingeführt, deren Abstand und Walzdruck derart gesteuert bzw. geregelt werden, daß der Block zwischen den Walzen aufgenommen und von ihnen mitgenommen wird. Damit diese Aufnalüe stattfinden kann, ist es bei den üblichen Betriebsbedingungen generell notwendig, den Berührungswinkel auf einen Wert zu begrenzen, der es nichterlaübt, ,eine Verringerung der ursprünglichen Dicke um mehr als 5©$ zu erzielen.In the known technique of rolling ingots of zinc or Zinc alloy, the block is inserted between rollers, their spacing and rolling pressure are controlled so that the Block is picked up between the rollers and taken away from them. So that this recording can take place, it is with the usual Operating conditions generally necessary, the contact angle to limit a value that does not allow, a decrease in original thickness by more than 5 © $.
Unter diesen Bedingungen müssen gerade wegen des geringen Kontaktwinkels mehrere Durchstiche vorgenommen werden, um zu der gewünschten Querschnittsverringerung zu kommen. Es bedarf dazu einer ge— wissen Zahl von BedienungsvorgSngen und von Steuerungen der Einrichtungen, die die Dauer des gesamten WalzVorganges verlängern. Under these conditions, precisely because of the small contact angle, several punctures have to be made in order to achieve the desired one Cross-sectional reduction to come. It requires a certain know the number of operating processes and controls of the devices that extend the duration of the entire rolling process.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Walzen von Blöcken aus Zink: oder Zinklegierung zu schaffen, das es ermöglicht, die Blockdicke bei einem einzigen Durchstich auf mindestens 4o# des ursprünglichen Wertes zu verringern, d.h. eine Dickenabnahme von mindestens 6o& bezogen auf die ursprüngliche Dicke, zu erzielen.The present invention is based on the object of a method for rolling ingots of zinc: or zinc alloy to create that makes it possible to reduce the block thickness to at least 4o # of the original value with a single puncture, i.e. a decrease in thickness of at least 6o & related to to achieve the original thickness.
Das erfindungsgemäße Verfahren ist im wesentlichen dadurch gekennzeichnet, daß die absolute Temperatur des Blockes zu Beginn des Walzens zwischen 65 und 8o# der absoluten Schmelztemperatur des den Block bildenden Zinks oder der Zinklegierung beträgt.The method according to the invention is essentially characterized in that that the absolute temperature of the ingot at the beginning of the rolling is between 65 and 8o # of the absolute melting temperature of the zinc or the zinc alloy forming the block.
Vorteilhafterweise liegt die absolute Temperatur des Blockes zuThe absolute temperature of the block is advantageously too

Gemäß einer besonders vorteilhaften Durchführung des erfindungsgemäßen Verfahrens werden beim Walzen des Blockes die Walzzylinder nur auf der Austrittsseite des Walzproduktes gekühlt, um dadurch jede Temperaturverringerung des Blockes vor seiner Aufnahme zwischen die Zylinder zu verhindern.According to a particularly advantageous implementation of the invention In the process, when the ingot is rolled, the rolling cylinders are only cooled on the exit side of the rolled product, thereby preventing any decrease in temperature of the block before it is received between the cylinders.
Beispielsweise erlaubt das erfindungsgemäße Verfahren, ein mit dem Block aus gewöhnlichem Zink, dessen Temperatur zu Beginn des Walzens 25o°C beträgt, gewalzt wird, die Dicke dieses Blockes von IjJ mm in einem einzigen Durchstich zwischen Walzzylindern von loo mm Durchmesser auf J5 mm mit einer Geschwindigkeit von 3o m/min zu verringern.For example, the inventive method allows a with the block of ordinary zinc, the temperature of which is 25o ° C at the beginning of the rolling, is rolled, the thickness of this block of IjJ mm in a single puncture between rolling cylinders from 100 mm in diameter to 5 mm at a speed of 3o m / min to decrease.

Durch das erfindungsgemäße Verfahren ist es möglich, Verringerungen der Bloekdicke zu erreichen, die mit den herkömmlichen Verfahren zwei oder drei aufeinanderfolgende Durchstiche erfordern wurden.The method according to the invention makes it possible to achieve reductions the bloek thickness, which with conventional methods require two or three consecutive punctures became.
Unter den Vorteilen, die das erfindungsgemäße Verfahren gegenüber
den durch die bekannten Einrichtungen in die Praxis eingeführten Verfahren zum Walzen von Zinkblöcken aufweist, können
die erheblich »iedrigeren Investitionskosten, weniger Bedienungspersonal
und im Falle der Verwendung von Walzzylindern kleinen Durchmessers ein erheblich geringer Gesamtenergieverbrauch erwähnt
werden.Among the advantages which the method according to the invention has over the methods for rolling zinc blocks introduced into practice by the known devices can be
the considerably lower investment costs, fewer operating personnel and, in the case of the use of small-diameter rolling cylinders, a considerably lower total energy consumption are mentioned.
