Abstract

A method and apparatus for making a molten film of metal, in particular a steel film, more uniform by strip casting, in which the molten material which is applied to a revolving belt is to have a thickness and properties which are as uniform as possible across the width of the film. To make the film more uniform over its width, forces are introduced into the metal film with a component which is directed oppositely to the direction in which the film is conveyed, which forces make the profile of the molten film of metal more uniform.

Description

Die Erfindung betrifft ein Verfahren zum Vergleichmäßigen eines durch Bändgießen erzeugten schmelzflüssigen Metallfilmes, insbesondere eines Stahlfilmes, entsprechend dem Oberbegriff des 1. Patentanspruches und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for leveling a band casting produced molten metal film, in particular a steel film, according to the preamble of claim 1 and a device for Execution of the procedure.

Die Erfindung ist überall dort anwendbar, wo ein schmelzflüssiger Metallfilm, insbesondere aus Stahl, auf ein Substrat, insbesondere auf ein umlaufendes Transportband, in Form einer Schmelze aufgebracht wird und eine möglichst gleiche Dicke und möglichst gleiche Eigenschaften über die Breite des Bandes aufweisen soll.The invention can be used wherever a molten metal film, in particular made of steel, on a substrate, in particular on a rotating one Conveyor belt, is applied in the form of a melt and the same as possible Thickness and the same properties as possible should have across the width of the belt.

Beim Bandgießen von Metall, insbesondere Stahl, kann entsprechend der benötigten Dicke beim Fertigwalzen sowie bei der erforderlichen Warmverformung zur Erzielung ausreichender Materialeigenschaften die Gießdicke des Bandes weitgehend optimal gewählt werden. Dabei ist es bekannt, das schmelzflüssige Metall durch entsprechende Verfahren und Vorrichtungen so zu kühlen, daß die Strangoberfläche des flüssigen Metallstranges durch Kontakt mit einem inerten Gas gleichmäßig gekühlt wird.When strip casting metal, especially steel, can be according to the required Thickness during finish rolling as well as with the required hot forming to achieve sufficient material properties, the casting thickness of the strip is largely optimal to get voted. It is known to pass through the molten metal appropriate methods and devices to cool so that the strand surface of the liquid metal strand cooled evenly by contact with an inert gas becomes.

Die DE 44 07 873 A beschreibt ein Verfahren und eine Vorrichtung zum Kühlen schmelzflüssigen Stahles, bei dem Düsen in einem Winkel zwischen 0 und 50 ° in Gießrichtung auf die Oberfläche des Stahlstranges gerichtet werden, wodurch die Stahloberfläche gleichmäßig und gezielt abgekühlt wird. Dadurch kann jegliche Verzunderung vermieden und eine gezielte Wärmeabfuhr erreicht werden, wodurch.die Oberflächenspannung gezielt beeinflußt wird und die gewünschte Qualität des Stahlstranges bzw. des Stahlbandes erreicht wird. Wichtig für die Qualität eines Bandes aus Stahl ist aber weiterhin seine gleichbleibende Dicke im Zusammenhang mit gleichbleibenden Materialeigenschaften über die Breite des Bandes, was nicht in jedem Fall ohne weiteres durch das Aufgeben auf das Transprtband erreichbar ist.DE 44 07 873 A describes a method and a device for cooling molten steel, with nozzles at an angle between 0 and 50 ° in Pouring direction be directed to the surface of the steel strand, causing the Steel surface is cooled evenly and specifically. Anyone can Scaling avoided and targeted heat dissipation achieved, which affects the surface tension and the desired quality the steel strand or the steel strip is reached. Important for the quality of a Steel strip is still related to its constant thickness with constant material properties across the width of the belt, which is not in in any case can be easily reached by posting on the conveyor belt.

Es ist daher Aufgabe der Erfindung, den Stand der Technik dahingehend zu verbessem, daß eine Möglichkeit gefunden wird, einen Film schmelzflüssigen Metalls vor und nach seinem Auftreffen auf das Transportband so zu verändern, daß er über seine Breite eine gleichmäßige Dicke mit gleichmäßigen Materialeigenschaften aufweist.It is therefore an object of the invention to the state of the art improve that a way is found a film of molten metal change before and after it hits the conveyor belt so that it over its width is a uniform thickness with uniform material properties having.

Diese Aufgabe wird verfahrensmäßig durch den Patentanspruch 1 und vorrichtungsmäßig durch den Patentanspruch 13 gelöst.This object is procedurally by claim 1 and solved in terms of device by claim 13.

Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.The sub-claims reflect advantageous embodiments of the invention.

Die erfindungsgemäße Lösung sieht vor, daß zum Vergleichmäßigen des aufgebrachten Metallfilmes auf dem Gießband über dessen Breite Kräfte eingeleitet werden, die eine Vergleichmäßigung des schmelzflüssigen Metalls bewirken.The solution according to the invention provides that the applied metal film initiated on the casting belt across its width forces become, which cause an equalization of the molten metal.

Vorteilhaft für die Erfindung ist, daß diese Kräfte über die Breite des Bandes entgegen der Transportrichtung des Metallfilmes in diesen so eingeleitet werden. Hierzu soll die auf das Transportband fließende Schmelze durch die Krafteinwirkung abgebremst werden. Strömt der Schmelzenfilm schneller als das Transportband, so ist der von der Schmelze ausgefüllte Querschnitt kleiner als der Querschnitt des sich synchron zum Transportband bewegenden Schmelzenfilmes (Sollquerschnitt). Ein solcher, nicht ausreichend ausgefüllter Querschnitt ist nachteilig.
Durch ein Abbremsen und Aufstauen der Schmelze wird ein gleichmäßiges Ausfüllen des Querschnittes erreicht. Ein zu starkes Abbremsen und eine Überhöhung des Schmelzenfilmes ist zu vermeiden. Anders als bei DE 44 07 873 A steht die geometrische Vergleichmäßigung, auch wenn es über einen Gasstrom erreicht wird, und nicht die Abkühlung im Vordergrund. Entsprechend ergeben sich wesentliche unterschiedliche Merkmale für die Gasströmung. Weiter begünstigt wird die Querschnittsvergleichmäßigung durch senkrecht zur Oberfläche wirkende Kraftkomponenten. It is advantageous for the invention that these forces are introduced into the metal film against the transport direction of the metal film over the width of the band. For this purpose, the melt flowing onto the conveyor belt is to be braked by the action of force. If the melt film flows faster than the conveyor belt, the cross section filled by the melt is smaller than the cross section of the melt film moving synchronously with the conveyor belt (nominal cross section). Such a cross-section which is not sufficiently filled is disadvantageous.
By braking and accumulating the melt, the cross section is evenly filled. Avoid decelerating too much and increasing the melt film. In contrast to DE 44 07 873 A, the geometric homogenization, even if it is achieved via a gas flow, and not the cooling is in the foreground. Accordingly, there are significantly different characteristics for the gas flow. The cross-sectional uniformity is further favored by force components acting perpendicular to the surface.

Vorteilhaft ist es, diese Kräfte entgegen der Transportrichtung des Bandes durch einen auf das Band gerichteten Gasstrom aufzubringen. Geeignet als Gase sind Inertgase, wie Argon oder Stickstoff, ggf. mit Beimischung reduzierender Komponenten, beispielsweise H2, CO, oder oxydierender, oberflächenspannungsbeeinflussender Komponenten, wie O2, CO2.It is advantageous to apply these forces against the direction of transport of the belt by means of a gas stream directed onto the belt. Inert gases, such as argon or nitrogen, are suitable as gases, optionally with admixing reducing components, for example H 2 , CO, or oxidizing components which influence the surface tension, such as O 2 , CO 2 .

Vorteilhaft ist es weiterhin, das Gas in gleichmäßigen Abständen auf den Metallfilm aufzubringen. Das kann erreicht werden durch eine Reihe von Düsen, die nebeneinander angeordnet sind und so betrieben werden, daß der auströmende Gasvolumenstrom eine Kraft auf die Oberfläche des flüssigen Metallfilmes ausübt. Diese Kraft führt dazu, daß die Gasstrahlen mindestens zu 50 % der Dicke des Metallfilmes in diesen eindringen. Dabei muß die Intensität eines jeden Gasstrahles so bemessen sein, daß ein Aufspritzen des flüssigen Metalls und ein Dispergieren von Gasblasen in die Schmelze vermieden wird.It is also advantageous to apply the gas at regular intervals Apply metal film. This can be achieved through a number of Nozzles that are arranged side by side and are operated so that the exiting gas volume flow exerts a force on the surface of the liquid metal film. This force causes the gas jets Penetrate at least 50% of the thickness of the metal film. there the intensity of each gas jet must be such that a Spraying the liquid metal and dispersing gas bubbles in the Melt is avoided.

Vorteilhaft ist es weiterhin, Gasdüsen neben- und hintereinander so anzuordnen, daß diese quasi die Form eines Rechens haben. Dadurch wird erreicht, daß der der Ausströmrichtung des Gases entgegentransportierte flüssige Metallfilm von den austretenden Gasstrahlen wie mit einem Rechen behandelt wird, wodurch es zu einer Abbremsung und Vergleichmäßigung der Schmelze über die Breite des Bandes kommt. Besonders vorteilhaft sind, jeweils versetzt, zwei oder mehrere hintereinander angeordnete Rechen in der Wirkungsweise eines Pascal'schen Dreiecks. Dadurch wird eine weitestgehend gleiche Dicke des Bandes über seine Breite und eine Vergleichmäßigung der Materialeigenschaften über dieselbe erreicht.It is also advantageous to have gas nozzles side by side and one behind the other to arrange that these have the form of a calculation. This will achieved that the transported against the outflow direction of the gas liquid metal film from the escaping gas jets like with a rake is treated, causing a deceleration and smoothing the melt comes across the width of the belt. Are particularly advantageous each offset, two or more rakes arranged one behind the other in the mode of action of a Pascal triangle. This will make one largely the same thickness of the tape over its width and one Uniformity of the material properties achieved over the same.

Vorteilhaft ist es weiterhin, die Düsen in einem Winkel so anzuordnen, daß der Gasstrom entgegen der Fließrichtung des gegossenen Bandes in einem Winkel zwischen 10 und 80 ° zur Senkrechten auf die Oberfläche des Schmelzenfilmes auftrifft. Für eine gezielte Steuerung der Dicke des gegossenen Bandes ist es weiterhin vorteilhaft, die Dicke des Schmelzenfilmes nach der Aufgabe durch geeignete Sensoren zu erfassen und über eine geeignete Regeleinrichtung den Gasstrom aus den Düsen dahingehend zu steuern, daß dieser gezielt auf die Dicke des Bandes über die Bandbreite Einfluß nimmt. It is also advantageous to arrange the nozzles at an angle such that the gas flow against the direction of flow of the cast strip in one Angle between 10 and 80 ° to the perpendicular to the surface of the Melt film hits. For a targeted control of the thickness of the cast tape, it is also advantageous to adjust the thickness of the Detect melt film after the task by suitable sensors and the gas flow from the nozzles via a suitable control device to control that this specifically on the thickness of the tape the bandwidth influences.

Weiterhin ist es vorteilhaft, auf den Metallfilm ein erstarrungsinitiierendes Mittel aufzubringen, um eine vorteilhafte Erstarrung der Oberfläche zu erreichen. Für Stahl wird beispielsweise als erstarrungsinitiierendes Mlttel ein oxydierendes CO2-haltiges Gas verwendet, was bewirkt, daß eine dünne Randschicht des Schmelzfilmes entkohlt und damit die Erstarrungstemperatur über die tatsächliche Temperatur soweit angehoben werden kann, daß die Erstarrung von der Oberseite aus einsetzt. Der CO2-Gehalt muß dazu so gering gehalten werden, daß keine Schlackebildung erfolgt.Furthermore, it is advantageous to apply a solidification-initiating agent to the metal film in order to achieve an advantageous solidification of the surface. For steel, for example, an oxidizing CO 2 -containing gas is used as the solidification-initiating material, which causes a thin surface layer of the melt film to decarburize and thus the solidification temperature can be raised above the actual temperature to such an extent that the solidification starts from the top. For this purpose, the CO 2 content must be kept so low that no slag is formed.

Als erstarrungsinitiierende Mittel können auch ein kühlendes und keimbildendes Pulver, beispielsweise Metallpulver, eine flüssige Schlacke, ein Gas oder ein weiteres flüssiges Metall Anwendung finden.A cooling and nucleating powder, for example metal powder, a liquid slag, a gas or another liquid metal find application.

Nachfolgend wird die Erfindung an 2 Figuren und einem Ausführungsbeispiel näher erläutert.The invention is illustrated below with two figures and an exemplary embodiment explained in more detail.

Die Figuren 1 und 2 zeigen die Situation mit Strömungsmodifikationen. Aus einem zwei Kammern enthaltenden Kupferprofil 6, wovon eine Kammer der Gaszuführung und eine der Wasserkühlung des Kupferprofils 6 dient, treten in zwei Reihen an versetzt angeordneten Positionen die Gasstrahlen 7 aus Gasdüsen 3 mit 1 mm Durchmesser großen Bohrungen aus.
Diese Gasstrahlen 7 treffen mit einem Winkel von 30 ° zur Senkrechten der Oberfläche entgegen der Gießrichtung auf die auf das Transportband 2 auffließende Schmelze auf und bremsen diese ab.
Gemäß der reduzierten mittleren Geschwindigkeit vergrößert sich der Strömungquerschnitt auf das Sollmaß. Darüber hinaus kann in der aufgestauten Schmelze zwischen dem Aufgabepunkt und dem Auftreffbereich des Gases ein Ausgleich der Schmelze in Querrichtung zur Erzielung eines gleichmäßigen Dickeprofils stattfinden. Die Wirkung der Gasströmung in der beschriebenen Form kann insgesamt verglichen werden mit der eines Rechens zur Erzielung einer gleichmäßigen Materialverteitung ("Pascal'scher Argonrechen").
Als zusätzliche Option kann ein entsprechender Argonrechen eingesetzt werden, um bereits auf der Zuführebene für eine gleichmäßige Materialverteilung zu sorgen. Figures 1 and 2 show the situation with flow modifications. The gas jets 7 emerge from gas nozzles 3 with 1 mm diameter bores in two rows at staggered positions from a copper profile 6 containing two chambers, one of which serves for gas supply and one for water cooling of the copper profile 6.
These gas jets 7 impinge on the melt flowing onto the conveyor belt 2 at an angle of 30 ° to the vertical of the surface against the pouring direction and slow them down.
According to the reduced average speed, the flow cross-section increases to the target size. In addition, a compensation of the melt in the transverse direction can take place in the pent-up melt between the application point and the impact area of the gas in order to achieve a uniform thickness profile. The effect of the gas flow in the form described can be compared overall with that of a rake to achieve a uniform material distribution ("Pascal's Argon Rake").
As an additional option, an appropriate argon rake can be used to ensure even material distribution on the feed level.

Vorteilhaft zur Vergleichmäßigung des Metallfilmes 4 ist weiterhin die Oszillation solcher Argonrechen transversal zur Metallströmung. That is also advantageous for the homogenization of the metal film 4 Oscillation of such argon rakes transverse to the metal flow.
