Description
Die vorliegende Patentanmeldung betrifft ein Verfahren und eine Vorrichtung zur Herstellung eines Magnesiumblechs aus einem Magnesiumband in einer Walzeinrichtung.The present patent application relates to a method and an apparatus for producing a magnesium sheet from a magnesium strip in a rolling device.
Der Herstellung von Magnesiumblech kommt aufgrund der sich entwickelnden Nachfrage eine zunehmende Bedeutung zu. Insbesondere hat sich gezeigt, dass sich Magnesiumblech für die Herstellung von Fahrzeugkarosserien eignet, wobei das Magnesiumblech bei Festigkeitseigenschaften, die mit denen von Aluminiumblech vergleichbar sind, ein geringeres Gewicht aufweist.The production of magnesium sheet is becoming increasingly important due to the evolving demand. In particular, it has been found that magnesium sheet is suitable for the production of vehicle bodies, wherein the magnesium sheet has a lower weight with strength properties that are comparable to those of aluminum sheet.
Die Herstellung von Magnesiumblech ist jedoch im Vergleich zur Herstellung von Stahl- oder Aluminiumblech vergleichsweise aufwendig, da Magnesium durch seine hexagonale Gitterstruktur bei den üblicherweise beim Kaltwalzen vorliegenden Verarbeitungstemperaturen schlecht verformbar ist. Zur erfolgreichen Herstellung von Magnesiumblech ist daher die Einhaltung eines definierten Temperaturbereichs notwendig, der etwa zwischen 230°C und 450°C liegt.However, the production of magnesium sheet is comparatively expensive compared to the production of steel or aluminum sheet, since magnesium is poorly deformable due to its hexagonal lattice structure at the processing temperatures normally used during cold rolling. For the successful production of magnesium sheet, it is therefore necessary to adhere to a defined temperature range, which is approximately between 230 ° C and 450 ° C.
Walzeinrichtungen zur Herstellung eines Magnesiumbands sind im Stand der Technik bekannt. Beispielsweise offenbart die
Aus der
Die
Bei den bekannten Fertigwalzeinrichtungen erzeugen die zusätzlichen Heizeinrichtungen in den Walzen oder der zusätzliche Durchlaufofen einen erhöhten Installations- und Betriebsaufwand für die Fertigwalzeinrichtung dar, was auch insbesondere den Energiebedarf zum Betrieb der Fertigwalzeinrichtung betrifft.In the known finishing roller devices, the additional heating devices in the rollers or the additional continuous furnace generate an increased installation and operating costs for the finishing roller device, which also relates in particular to the energy requirement for operating the finishing roller device.
Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde ein Verfahren und eine Vorrichtung zum Umformen eines Magnesiumbands zur Verfügung zu stellen, das die vorstehenden Nachteile beseitigt und eine effektivere Wärmeführung des Magnesiumbands in der Fertigwalzeinrichtung ermöglicht und wobei keine aufwendige Umbaumaßnahmen der Anlage erforderlich sind.The present invention is therefore based on the object to provide a method and an apparatus for forming a magnesium tape, which eliminates the above disadvantages and a more effective thermal management of the magnesium tape allows in the finishing roller device and wherein no complex conversion measures of the system are required.
Gelöst werden diese Aufgaben durch ein Verfahren mit den Merkmalen gemäß Patentanspruch 1 und eine Walzvorrichtung mit den Merkmalen gemäß Patentanspruch 9.These objects are achieved by a method having the features according to
Bei dem erfindungsgemäßen Walzverfahren wird ein Magnesiumband nach Vorwärmen durch mindestens einen von mindestens einem Paar von gegenläufigen Arbeitswalzen, die einen Walzengrundkörper umfassen, gebildeten Walzspalt geführt, wobei mindestens eine der beiden gegenläufigen Arbeitswalzen mindestens eine den Walzengrundkörper umgebende wärmeisolierende Ummantelung umfasst.In the rolling process according to the invention, a magnesium strip is passed, after preheating, through at least one nip formed by at least one pair of counter-rotating work rolls comprising a roll base, at least one of the two counter-rotating work rolls comprising at least one heat-insulating jacket surrounding the roll base.
Die wärmeisolierende Ummantelung kann ein- oder mehrschichtig sein. Die wärmeisolierende Eigenschaft der Ummantelung kann durch die Wahl des Ummantelungsmaterials und/oder durch strukturierte, die Berührungsflächen reduzierende Oberflächen zwischen der Ummantelung und dem Walzengrundkörper erzeugt werden.The heat-insulating sheath may be single or multi-layered. The heat-insulating property of the sheath may be generated by the choice of sheath material and / or by structured interfacial surfaces between the sheath and the roll body.
Es ist bevorzugt, dass die wärmeisolierende Ummantelung aus einem keramischen Material besteht. Beispielsweise kann das keramische Material der Ummantelung aus Siliciumnitrid (Si3N4), Bornitrid (BN), Borcarbid (B4C), Calciumhexaborid (CaB6), Siliciumcarbid (SiC), Titanborid (TiB2), Zinkborid (ZnB2) oder Mischkeramiken derselben bestehen. Dieses Material zeichnet sich neben einer guten Wärmeisolierung durch große mechanische Festigkeit, Hochtemperaturbeständigkeit und eine geringe Adhäsionsneigung gegenüber metallischen Werkstoffen aus. Andere keramische Materialien mit ähnlichen Eigenschaften sind aber ebenfalls geeignet. Ferner sind keramische Materialien für die Ummantelung vorteilhaft, weil mit ihrem Gebrauch gegebenenfalls auf ein Schmiermittel verzichtet werden kann.It is preferable that the heat-insulating jacket is made of a ceramic material. For example, the ceramic material of the sheath may be made of silicon nitride (Si 3 N 4 ), boron nitride (BN), boron carbide (B 4 C), calcium hexaboride (CaB 6 ), silicon carbide (SiC), titanium boride (TiB 2 ), zinc boride (ZnB 2 ). or mixed ceramics thereof. In addition to good thermal insulation, this material is characterized by high mechanical strength, high-temperature resistance and a low adhesion tendency to metallic materials. However, other ceramic materials with similar properties are also suitable. Furthermore, ceramic materials are advantageous for the sheathing because, if necessary, a lubricant can be dispensed with with their use.
Gemäß einer weiteren Ausführungsform der Erfindung weist mindestens eine Arbeitswalze, vorzugsweise beide Arbeitswalzen, zusätzlich eine wärmespeichernde Ummantelung auf. Es ist bevorzugt, dass die wärmespeichernde Ummantelung die wärmeisolierende Ummantelung umgibt.According to a further embodiment of the invention, at least one work roll, preferably both work rolls, in addition to a heat-storing sheath. It is preferable that the heat-storage jacket surrounds the heat-insulating jacket.
Das erfindungsgemäße Verfahren wird vorzugsweise so durchgeführt, dass bei den ersten Stichen eines Stichplans eine geringere Walzgeschwindigkeit gewählt wird, als im weiteren Walzverlauf eines Stichplans, und die Walzgeschwindigkeit im weiteren Walzverlauf eines Stichplans erhöht wird. Die vergleichsweise langsamere Geschwindigkeit bei den ersten Stichen eines Stichplans läßt die im Magnesiumband gespeicherte Wärme in die kühlere Ummantelung der Walze abfließen. Die wärmeisolierende oder wärmespeichernde Ummantelung verhindert den Wärmefluss in den Grundkörper der Walze. Im weiteren Walzverlauf des Stichplans gibt die so erwärmte Ummantelung bei zunehmender Abkühlung des Metallbands wieder Wärme an das Metallband ab. Die mit steigender Walzgeschwindigkeit steigende Umformungswärme sorgt für zusätzliche Erwärmung des Metallbands.The method according to the invention is preferably carried out such that a lower rolling speed is selected in the first stitches of a stitch plan than in the further rolling course of a stitch plan, and the rolling speed is increased in the further rolling course of a stitch plan. The comparatively slower speed of the first stitches of a stitch plan causes the heat stored in the magnesium band to flow away into the cooler shell of the roll. The heat-insulating or heat-storing jacket prevents the heat flow in the main body of the roller. In the further Walzverlauf the stitch plan, the thus heated casing returns with increasing cooling of the metal strip heat to the metal strip. The increasing heat of transformation with increasing rolling speed ensures additional heating of the metal strip.
Wenn eine wärmespeichernde Ummantelung die wärmeisolierende Ummantelung umgibt wird dieser Effekt zusätzlich verstärkt. Es ist eine geringere Vorheizung des Magnesiumbands erforderlich.If a heat-storing sheath surrounds the heat-insulating sheath, this effect is additionally enhanced. There is a lower preheating of the magnesium tape required.
Das Verfahren kann in einem herkömmlichen Reversierwalzwerk durchgeführt werden. Ebenfalls ist dort, wo temperiertes Band die Herstellungskomponenten berührt, eine wärmeisolierende Ummantelung vorteilhaft. Alternativ kann es auch in einer mehrgerüstigen Tandemstraße eingesetzt werden, wie z.B. die in der
Das erfindungsgemäße Verfahren und die erfindungemäße Walzvorrichtung können vorteilhaft auch in einem Verfahren zum flexiblen Walzen verwendet werden, bei dem bei dem das Bandmaterial in Längsrichtung des Walzvorgangs über die gesamte Länge von einer Ausgangsdicke auf eine über der Länge veränderliche Enddicke ausgewalzt wird.The method according to the invention and the rolling device according to the invention can advantageously also be used in a method of flexible rolling, in which the strip material is rolled in the longitudinal direction of the rolling process over the entire length from an initial thickness to an end thickness that varies over the length.
Im Folgenden werden bevorzugte Ausführungsformen der Erfindung unter Bezugnahme auf die folgenden Figuren näher erläutert, wobei:
-
Fig. 1 die Ein- und Auslaufdicke [mm] eines erfindungsgemäßen Stichplans darstellt, -
Fig. 2 die Bandlängenzunahme [m] eines erfindungsgemäßen Stichplans darstellt, -
Fig. 3 die Walzgeschwindigkeiten [m/min] eines erfindungsgemäßen Stichplans darstellt, -
Fig. 4 die logarithmische Einzel- und Gesamtumformung [phi] eines erfindungsgemäßen Stichplans darstellt, -
Fig. 5 die Umformgeschwindigkeit/Stich [Phi/s] eines erfindungsgemäßen Stichplans darstellt und -
Fig. 6 die Bandtemperatur [°C] inkl. Speicherwärme- (schwalz) und Umformwärmeanteil (dunkelgrau) eines erfindungsgemäßen Stichplans darstellt.
-
Fig. 1 represents the inlet and outlet thickness [mm] of a stitch plan according to the invention, -
Fig. 2 represents the band length increase [m] of a stitch plan according to the invention, -
Fig. 3 represents the rolling speeds [m / min] of a pass schedule according to the invention, -
Fig. 4 represents the logarithmic single and total transformation [phi] of a pass plan according to the invention, -
Fig. 5 represents the forming speed / stitch [Phi / s] of a stitch plan according to the invention and -
Fig. 6 the strip temperature [° C] incl. Speicherwärme- (Schwalz) and Umformwärmeanteil (dark gray) represents a stitch plan according to the invention.
Wir aus den Figuren ersichtlich ist, nimmt der Speicherwärmeund Umformanteil bei Verwendung einer wärmeisolierenden Ummantelung der Walze kontinuierlich zu, was dazu führt, dass das Walzgut aus Magnesium schon beim zweiten Stichplan kaum noch zusätzlich beheizt werden muss.As can be seen from the figures, the storage heat and forming rate decreases when using a heat-insulating jacket the roller continuously to, which means that the rolling stock of magnesium hardly needs to be additionally heated in the second stitch plan.
