Abstract

Die Aufgabe, ein Verfahren und eine Vorrichtung zur Herstellung von Warmband (1) mittels Zweiröllen-Dünnbandgießanlagen (2) anzugeben, mit welchen eine wesentliche Steigerung des Produktionsdurchsatzes "P" über die durch die Erstarrungszeit "t" der Stranghäute (14a; 14b) gesetzten Grenzen für herkömmliche Zweirollen-Dünnbandgießanlagen (2) möglich ist, wird im Wesentlichen dadurch gelöst, dass die beiden Stranghäute (14a; 14b) derart abschnittsweise definiert zusammengepreßt oder zueinander beabstandet werden, dass sich ein Warmband (1) mit örtlich begrenzten und variablen Materialquerschnitten ausbildet.

Figure 00000001
The task of specifying a method and a device for the production of hot strip (1) by means of two-roller thin strip casting plants (2), with which a substantial increase in the production throughput "P" over the solidification time "t" of the strand skins (14a; 14b) is set Limits for conventional two-roll thin-strip casting systems (2) is essentially solved by pressing the two extruded skins (14a; 14b) together in sections in a defined manner or spacing them apart in such a way that a hot strip (1) is formed with locally limited and variable material cross sections ,
