Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Gießguts aus flüssigem Metall nach dem Oberbegriff von Anspruch 1.The invention relates to a method for producing a cast material from liquid metal according to the preamble of claim 1.
Nach dem Stand der Technik sind insbesondere zur Herstellung von Aluminiumlegierungen Horizontal-Blockgießmaschinen bekannt, die nach Art einer umlaufenden Raupengießmaschine funktionieren. Eine solche Gießmaschine ist z.B. aus
Bei einer herkömmlichen Horizontal-Blockgießmaschine kann die Neigung einer Einheit bestehend aus der oberen und unteren Gießraupe relativ zur Horizontalen eingestellt bzw. verändert werden. Hierzu umfasst diese Blockgießmaschine eine Spindelhubvorrichtung, die mit den vier Eckbereichen der Blockgießmaschine in Wirkverbindung steht. Zur Ausrichtung der aus den Gießraupen gebildeten Einheit sind beim Einsatz der Spindelhubvorrichtung Messdosen und Messuhren installiert. Nachteilig hierbei ist, dass die Stellmotoren bzw. Aktuatoren der Spindelhubvorrichtung nicht synchronisiert sind, dass definierte Positionen für die Gießraupen nicht wiederholt angefahren werden können, dass keine aktive Gießspaltbeeinflussung möglich ist, und dass lange Rüstzeiten erforderlich sind, um die aus den Gießraupen gebildete Einheit auf einen neuen Betriebszustand einzustellen. Ein weiterer Nachteil besteht darin, dass eine Lage der Gießraupen relativ zueinander nicht exakt angesteuert werden kann, wobei eine Automatisierung mittels eines Steuer-/Regelkonzepts ebenfalls nicht gegeben ist.In a conventional horizontal ingot casting machine, the inclination of a unit consisting of the upper and lower casting bead can be adjusted or changed relative to the horizontal. For this purpose, this ingot casting machine comprises a spindle lifting device which is in operative connection with the four corner areas of the ingot casting machine. To align the unit formed from the casting beads, measuring cells and dial gauges are installed when the spindle lifting device is used. The disadvantage here is that the servomotors or actuators of the spindle lifting device are not synchronized, that defined positions for the casting beads cannot be repeatedly approached, that no active influence on the casting gap is possible, and that long set-up times are required to open the unit formed from the casting beads to set a new operating state.

Entsprechend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Herstellen eines Gießguts aus flüssigem Metall hinsichtlich einer Variabilität des Herstellungsprozesses zu optimieren.Accordingly, the invention is based on the object of optimizing a method for producing a cast material from liquid metal with regard to the variability of the production process.
Diese Aufgabe wird durch ein Verfahren mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in dem abhängigen Anspruch definiert.This object is achieved by a method with the features specified in claim 1. Advantageous developments of the invention are defined in the dependent claim.
Die vorliegende Erfindung sieht ein Verfahren zum Herstellen eines Gießguts aus flüssigem Metall vor. Hierbei wird das flüssige Metall in eine sich bewegende Gießform vergossen, die zwischen Kühlblöcken, die an entlang von jeweils zwei gegenüberliegend angeordneten endlosen horizontalen Umlaufbahnen in einer Transportrichtung bewegten Tragelementen angebracht sind, gebildet ist. Gemäß einer Variante dieses Verfahrens ist vorgesehen, dass die Neigung einer Einheit gebildet aus der oberen und unteren Raupe relativ zur Horizontalen insbesondere beim Angießen eingestellt wird, indem zumindest ein Aktuator, der mit der aus der oberen und unteren Raupe gebildeten Einheit wirkverbunden ist, angesteuert wird. Nach einer alternativen Variante des Verfahrens ist vorgesehen, dass die Neigung entweder der oberen oder der unteren Raupe in Richtung ihre Längsachse relativ zu der jeweils anderen Raupe verändert wird, indem zumindest ein Aktuator, der mit einer Rahmeneinrichtung, an der eine für diese Raupe eine endlose Umlaufbahn bildende Führungsschiene angebracht ist, wirkverbunden ist, angesteuert wird. Die Ansteuerung des zumindest einen Aktuator erfolgt durch eine Steuerungseinrichtung.The present invention provides a method of making a cast from liquid metal. In this case, the liquid metal is poured into a moving casting mold which is formed between cooling blocks which are attached to support elements which are moved in a transport direction along two oppositely arranged endless horizontal circulating tracks. According to a variant of this method it is provided that the inclination of a unit formed from the upper and lower bead is set relative to the horizontal, in particular during casting, in that at least one actuator, which is operatively connected to the unit formed from the upper and lower bead, is controlled . According to an alternative variant of the method, it is provided that the inclination of either the upper or the lower caterpillar is changed in the direction of its longitudinal axis relative to the respective other caterpillar by at least one actuator, which is connected to a frame device, on one of which is an endless one for this caterpillar Orbit forming guide rail is attached, is operatively connected, is controlled. The at least one actuator is controlled by a control device.
Im Sinne der vorliegenden Erfindung ist die Transportrichtung, in der die Tragelemente mit den daran angebrachten Kühlblöcken entlang der jeweiligen Führungsschienen und der hierdurch ausgebildeten Umlaufbahnen bewegt werden, gleichbedeutend mit der Gießrichtung, in der das flüssige Metall in die sich bewegende Gießform, die zwischen den Kühlblöcken in den geraden Abschnitten der gegenüberliegenden horizontalen Umlaufbahnen gebildet wird, vergossen wird.In the context of the present invention, the transport direction in which the support elements with the cooling blocks attached to them are moved along the respective guide rails and the thereby formed orbits is synonymous with the casting direction in which the liquid metal enters the moving casting mold between the cooling blocks is formed in the straight sections of the opposite horizontal orbits, is potted.
Die genannte Verstellung der aus den Raupen gebildeten Einheit oder zumindest einer Raupe relativ zur jeweils anderen Raupe bezüglich ihrer Neigung wird durch die Ansteuerung zumindest eines Aktuators erreicht, der mit einer Rahmeneinrichtung, an der die den Raupen zugeordneten Führungsschienen angebracht sind, wirkverbunden ist. Der zumindest eine Aktuator wird mittels der Steuerungseinrichtung in Abhängigkeit von zumindest einer vorbestimmten Prozessgröße kraftgeregelt, wobei diese Prozessgröße eine Kontaktkraft der oberen Raupe zu einer seitlichen Führungseinrichtung ist.The mentioned adjustment of the unit formed from the caterpillars or at least one caterpillar relative to the other caterpillar with regard to its inclination is achieved by controlling at least one actuator which is operatively connected to a frame device on which the guide rails assigned to the caterpillars are attached. The at least one actuator is force-regulated by means of the control device as a function of at least one predetermined process variable, this process variable being a contact force of the upper bead with a lateral guide device.
Der Erfindung liegt die wesentliche Erkenntnis zugrunde, dass durch eine Ansteuerung des zumindest einen Aktuators eine reproduzierbare Einstellung für die Raupengießmaschine möglich ist, nämlich hinsichtlich der Neigung entweder der aus der oberen und unteren Raupe gebildeten Einheit relativ zur Horizontalen, oder einer Raupe relativ zur jeweils anderen Raupe. Eine Verstellung bzw. Veränderung der Neigung der kompletten Einheit gebildet aus der oberen und unteren Raupe in ihrer Neigung relativ zur Horizontalen kann insbesondere beim Angießen, d.h. beim Beginn eines Gießprozesses, erfolgen. Hierdurch kann die Strömungsgeschwindigkeit des flüssigen Metalls innerhalb der Gießform reguliert werden. Beispielsweise kann durch ein Anheben des hinteren Bereichs der beiden Raupen, d.h. im Auslaufbereich der Gießform, erreicht werden, dass für die sich bewegende Gießform in bzw. entlang der Transportrichtung eine größere "Steigung" entsteht, weil der Auslaufbereich der Gießform höher angeordnet ist als deren Einlaufbereich. Alternativ hierzu kann zu Beginn des Gießvorgangs vorgesehen sein, den Auslaufbereich der Gießform nach unten zu schwenken, so dass die Schwerkraft dazu beiträgt, das flüssige Gießgut in die Gießmaschine bzw. deren sich bewegende Gießform zu bringen Hierdurch kann der Wärmeübergang vom Gießgut zur Kokille, d.h. zu den Kühlblöcken und somit die Temperaturführung des Gießguts bzw. eines daraus erzeugten Bands beeinflusst werden. Eine solche Veränderung der Neigung der Einheit gebildet aus der oberen und unteren Raupe kann auch automatisiert während des Gießprozesses erfolgen.The invention is based on the essential knowledge that by controlling the at least one actuator a reproducible setting for the caterpillar casting machine is possible, namely with regard to the inclination of either the unit formed from the upper and lower caterpillars relative to the horizontal or one caterpillar relative to the other Caterpillar. An adjustment or change of the inclination of the complete unit formed from the upper and lower bead in its inclination relative to the horizontal can take place in particular during casting, ie at the beginning of a casting process. This allows the flow rate of the liquid metal within the casting mold to be regulated. For example, by lifting the rear area of the two caterpillars, ie in the outlet area of the casting mold, a greater "slope" is created for the moving casting mold in or along the transport direction, because the outlet area of the casting mold is arranged higher than its Inlet area. Alternatively, it can be provided at the beginning of the casting process, the outlet area of the To pivot the casting mold downwards so that gravity contributes to bringing the liquid cast material into the casting machine or its moving casting mold. This allows the heat transfer from the cast material to the mold, ie to the cooling blocks and thus the temperature control of the cast material or one of it generated bands are affected. Such a change in the inclination of the unit formed from the upper and lower bead can also take place automatically during the casting process.
Ergänzend und/oder alternativ kann vorgesehen sein, dass die Neigung nur einer Raupe relativ zur jeweils anderen Raupe veränderlich ist bzw. verstellt wird. Hierdurch kann entweder eine exakte Planparallelität der beiden Raupen an ihren gegenüberliegenden Trums erreicht werden, oder auch ein gezielt keilförmiges Gussbandprofil eingestellt werden.In addition and / or as an alternative, it can be provided that the inclination of only one caterpillar is variable or adjusted relative to the other caterpillar. In this way, either an exact plane parallelism of the two caterpillars can be achieved on their opposite strands, or a specifically wedge-shaped cast strip profile can be set.
Die vorstehend genannten Möglichkeiten, entweder die Neigung einer aus den beiden Raupen gebildeten Einheit relativ gegenüber der Horizontalen und/oder die Neigung einer der beiden Raupen relativ zur jeweils anderen Raupe gezielt zu verändern, verbessert die Einstellbarkeit des Gießspalts bzw. der zwischen den beiden Raupen bewegten Gießform. In Folge dessen wird das Gussprofil optimiert und eine Reproduzierbarkeit der Qualität (Profil) des Gießguts erreicht. Des Weiteren wird durch eine Automatisierung der genannten Verstell-Funktionen eine Verkürzung der Rüstzeiten erreicht und eine Handhabung der Anlage erleichtert.The aforementioned possibilities of changing either the inclination of a unit formed from the two caterpillars relative to the horizontal and / or the inclination of one of the two caterpillars relative to the other caterpillar improves the adjustability of the casting gap or that moved between the two caterpillars Casting mold. As a result, the cast profile is optimized and the quality (profile) of the cast material can be reproduced. Furthermore, by automating the mentioned adjustment functions, the set-up times are shortened and handling of the system is made easier.
Im Zusammenhang damit, dass eine Steuerungseinrichtung vorgesehen ist, mittels welcher der zumindest eine Aktuator angesteuert werden kann, kann eine Betätigung dieses Aktuators elektromotorisch, pneumatisch oder hydraulisch erfolgen.In connection with the fact that a control device is provided by means of which the at least one actuator can be controlled, this actuator can be actuated by an electric motor, pneumatically or hydraulically.
In vorteilhafter Weiterbildung der Erfindung kann der zumindest eine Aktuator mittels der Steuerungseinrichtung in Abhängigkeit von zumindest einer vorbestimmten Prozessgröße positionsgeregelt werden. Diese vorbestimmte Prozessgröße kann gewählt sein aus der Gruppe gebildet aus insbesondere der Produkttemperatur, dem Verschleiß beteiligter Maschinenkomponenten, der Sorte des vergossenen Metalls, einer Umlaufgeschwindigkeit der Raupen, der gewählten Gießdicke und/oder der Gießbreite des Gießguts.In an advantageous development of the invention, the at least one actuator can be position-regulated by means of the control device as a function of at least one predetermined process variable. This predetermined process variable can be selected from the group formed in particular from the product temperature, the wear of the machine components involved, the type of metal being cast, the speed of the caterpillars, the selected casting thickness and / or the casting width of the cast material.
In vorteilhafter Weiterbildung der Erfindung kann der zumindest eine Aktuator mittels der Steuerungseinrichtung in Abhängigkeit von einer weiteren vorbestimmten Prozessgröße kraftgeregelt sein, wobei diese Prozessgröße aus der vergossenen Metallsorte gebildet ist.In an advantageous development of the invention, the at least one actuator can be force-regulated by means of the control device as a function of a further predetermined process variable, this process variable being formed from the cast metal type.
In vorteilhafter Weiterbildung der Erfindung kann vorgesehen sein, dass in der Steuerungseinrichtung, mittels welcher der zumindest eine Aktuator angesteuert wird, ein Modell hinterlegt ist. Auf Grundlage dieses Modells ist eine Automatisierung für die Ansteuerung des zumindest einen Aktuators auch während des Gießprozesses möglich, um damit die Neigung entweder von einer Raupe relativ zur jeweils anderen Raupe, oder aber der aus beiden Raupen gebildeten Einheit zu verändern. Beispielsweise kann auf Grundlage eines hinterlegten Modells eine elektrisch synchronisierte Einstellung der Raupe(n) erfolgen, wodurch es möglich ist, eine Raupe in jedweder Richtung gezielt anzustellen und eine hierfür definierte Position einfacher anzufahren.In an advantageous development of the invention, it can be provided that a model is stored in the control device by means of which the at least one actuator is controlled. On the basis of this model, automation for the control of the at least one actuator is also possible during the casting process in order to change the inclination either of one caterpillar relative to the other caterpillar, or of the unit formed from both caterpillars. For example, an electrically synchronized setting of the caterpillar (s) can take place on the basis of a stored model, which makes it possible to position a caterpillar in any direction in a targeted manner and to move to a position defined for this purpose more easily.
