Description

Verfahren zum spanlosen Ablängen gegossener Stränge während des Gießens Werden hochschmelzende Metalle beispielsweise nach dem Stranggießverfahren vergossen, so entstehen Stränge beträchtlicher Länge. Um nun einerseits die Bauhöhe bzw. Baulänge der Stranggießmaschine in brauchbaren Grenzen zu halten und um anderseits die erzeugten Stränge wegbefördern zu können, müssen sie nach erfolgter Erstarrung, jedoch noch im heißen Zustand, in transportfähige und für die Weiterverarbeitung geeignete Längen zerteilt werden. Für diesen Arbeitsgang sind bereits eine Reihe von Verfahren bekannt, z. B. das Warmsägen, Autogenschneiden, Einlegen von Schamotteringen u. dgl. mehr. Wird das Warmsägen oder Autogenschneiden angewendet, so ist zu beachten, daß die .Schneidvorrichtung in gleicher Geschwindigkeit mit dem Strang mitbewegt werden muß. Dies führt naturgemäß zu verhältnismäßig komplizierten maschinellen Einrichtungen, die nicht nur kostspielig sind, sondern auch besonderer Pflege bedürfen und eine verhältnismäßig hohe Reparaturanfälligkeit aufweisen.Process for the non-cutting cutting to length of cast strands during casting If high-melting metals are cast using the continuous casting process, for example, this creates strands of considerable length. Now, on the one hand, the overall height or overall length to keep the continuous casting machine within usable limits and on the other hand to keep the generated To be able to transport strands away, they still have to after solidification, however when hot, in transportable lengths suitable for further processing be cut up. A number of processes are already known for this operation, z. B. hot sawing, oxy-fuel cutting, inserting fireclay rings and the like. If hot sawing or oxy-fuel cutting is used, it must be ensured that the .Cutting device can be moved along with the strand at the same speed got to. Naturally, this leads to relatively complicated mechanical equipment, which are not only expensive, but also require special care and a have a relatively high susceptibility to repair.

Durch umfangreiche Versuche gelang es nun, ein Verfahren zu entwickeln, das sich durch ganz besondere Einfachheit und Betriebssicherheit auszeichnet. Beim erfindungsgemäßen Verfahren wird die Tatsache ausgenutzt, daß eine auf engen Querschnitt begrenzte äußerst schroffe Abkühlung zu einem zur Strangachse normalen Abreißen des Stranges führt. Überraschenderweise hat sich dabei gezeigt, daß die auf diese Art und Weise hervorgerufenen Bruchflächen nicht nur in der Tat normal zur Strangachse stehen, sondern überdies in hohem Maße eben sind, so daß sie in bezug auf die Weiterverarbeitung durchaus den Trennflächen, wie sie mit Block- oder Knüppelbrechern hergestellt werden können, entsprechen.Extensive tests have now made it possible to develop a process which is characterized by its very special simplicity and operational reliability. At the The method according to the invention takes advantage of the fact that a narrow cross-section limited extremely abrupt cooling to a tear normal to the strand axis of the strand leads. Surprisingly, it has been shown that on this This way the fracture surfaces are not only in fact normal to the strand axis stand, but are also to a large extent flat, so that they can be processed further definitely the parting surfaces as they are produced with block or billet crushers can correspond.

Die technische Durchführung des Verfahrens ist außerordentlich einfach, -sie besteht in der Anwendung einer den Strang umgebenden schlitzförmigen Düse, die in gleicher Geschwindigkeit mit dem Strang bewegt wird, aus der ein schmaler Wasserstrahl mit erhöhter Geschwindigkeit austritt und auf den Strang auftrifft. Diese partiell äußerst schroffe Abkühlung läßt man so lange einwirken, bis die Trennung erfolgt ist.The technical implementation of the process is extremely simple, - it consists in the use of a slot-shaped nozzle surrounding the strand, which is moved at the same speed with the strand from which a narrow one Water jet emerges at increased speed and strikes the strand. This partially extremely abrupt cooling is allowed to act until separation is done.

Besonders vorteilhaft ist dieses Verfahren anwendbar bei härtbaren Stählen und bei legierten Stählen. Wirtschaftlich bedeutet dieses Verfahren einen .großen Fortschritt, da es gegenüber den bisher üblichen Verfahren nahezu überhaupt keine Kosten verursacht.This method can be used particularly advantageously in the case of curable Steels and alloy steels. Economically, this process means one .big progress, as it is almost entirely possible compared to the previously usual procedures incurs no costs.
