Abstract (en)

Process for descaling the surface of a casting rod comprises elongating the rod (1) between the end of the rod support (10) and before the inlet to the compensating oven (11) or before the inlet to the roll stand (33) in a limited region by a two-stage deflection from the horizontal transporting device in the region of each deflection (4, 5), and intensively cleaning the rod surfaces (2, 3) especially in the deflecting regions (4, 5) using hard water jets (8, 9). An Independent claim is also included for an apparatus for carrying out the descaling process.

Abstract (de)

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Entzundern, insbesondere von Oszillationsmarken (30) aufweisenden Oberflächen (2, 3) eines im Stranggießverfahren herstellbaren Gußstranges (1), insbesondere von Dünnbrammen. Die Dünnbrammen werden in einer der Gießeinrichtung nachfolgenden Warmbandstraße (32) mit Ausgleichsofen (11) und mit vorzugsweise mehreren Walzgerüsten (33) dickenreduziert. Der Gußstrang (1) wird zwischen dem Ende der Strangstützung (10) und vor Einlauf in den Ausgleichsofen (11) oder vor Einlauf in die Walzgerüste in einem begrenzten Bereich (29) durch wenigstens zweifaches Auslenken aus seiner horizontalen Transportrichtung im Bereich jeder Auslenkung (4, 5) einer Dehnung seiner Oberflächen (2,3) unterworfen. Die Strangoberflächen (2, 3) werden insbesondere in den Auslenkungsbereichen (4, 5) mittels harter Wasserstrahlen (8, 9) einer intensiven Abreinigung unterzogen. <IMAGE>
