Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Erzeugung von beschichteten Strängen aus Metall, insbesondere von Bändern (1) aus Stahl, bei dem ein Metallstrang (1.1) durch den Boden eines Gefäßes (3), gefüllt mit Schmelze (3.3) gleicher oder unterschiedlicher Zusammensetzung wie der Metallstrang (1.1), geführt wird. Die Verweilzeit des Metallstranges (1.1) wird in Abhängigkeit von der Schmelzbadhöhe (3.3.1), der Gießgeschwindigkeit, der Metallstrangdicke und der Vorwärmtemperatur des Metallstranges so gewählt, daß die abgelagerte Schmelze auf dem Metallstrang eine gewünschte Dicke von dem Mehrfachen der Ausgangsdicke des Metallstranges annimmt. Nach Austritt aus dem Schmelzbad (3.3) erfährt der Metallstrang (1.1) mit ankristallisierter Schicht (3.6) einen Glättstich (2). Der Glättstich (2) wird dann vorgenommen, wenn die Oberflächentemperatur des ankristallisierten Stranges (2.6) kleiner als die Solidus-Temperatur des Schmelzbades (3.3) ist und damit zumindest die Oberfläche (1.3) der ankristallisierten Schicht (3.6) erstarrt ist.

Figure 00000001
The invention relates to a method and a device for producing coated strands of metal, in particular strips (1) of steel, in which a metal strand (1.1) through the bottom of a vessel (3) filled with melt (3.3) of the same or different Composition as the metal strand (1.1) is performed. The dwell time of the metal strand (1.1) is selected depending on the molten pool height (3.3.1), the casting speed, the metal strand thickness and the preheating temperature of the metal strand so that the deposited melt on the metal strand assumes a desired thickness of several times the initial thickness of the metal strand . After leaving the molten bath (3.3), the metal strand (1.1) with a crystallized layer (3.6) experiences a smoothing stitch (2). The smoothing stitch (2) is carried out when the surface temperature of the crystallized strand (2.6) is lower than the solidus temperature of the melt pool (3.3) and thus at least the surface (1.3) of the crystallized layer (3.6) has solidified.
