Abstract: Method for the manufacture of a steel strip, whereby molten steel is cast in a continuous casting machine into a slab and, while making use of the casting heat, is conveyed through a furnace apparatus, is roughed in a roughing apparatus, and finish-rolled in a finishing apparatus into a steel strip of a desired finished thickness, whereby in an endless or semi-endless process a. for the manufacture of a ferritically rolled steel strip, the slab is rolled in the roughing apparatus in the austenitic range and after the rolling in the austenitic range is cooled to a temperature whereby the steel has essentially a ferritic structure, and the strip, the slab or a part of the slab is rolled in the finishing apparatus at speeds essentially corresponding to the entry speed into the finishing apparatus and the subsequent thickness reductions and in at least one stand of the finishing apparatus is rolled in the ferritic range; b. for the manufacture of an austenitically rolled steel strip, the strip leaving the roughing apparatus is heated to or held at a temperature in the austenitic range and is rolled in the finishing apparatus essentially in the austenitic range to the finished thickness and, following that rolling, is cooled down to a temperature in the ferritic range; and the ferritically or austenitically rolled strip after reaching the desired finished thickness is cut to portions of the desired length which are subsequently coiled.

Abstract: Die Erfindung betrifft ein Verfahren zum Kühlen von walzwarmem Walzgut (1), insbesondere zum beidseitigen Kühlen von Warmbreitband, bei dem eine Zwangskonvektion beim Wärmeaustausch zwischen Walzgut (1) und Kühlmedium mit Hilfe einer Druckwasserströmung in einem Druckraum (10) und Konvektionsraum (13) vorgenommen und das Walzgut (1) durch gezieltes Steuern der Intensität der Zwangskonvektion gekühlt wird. Das Verfahren wird dadurch verbessert, daß die Intensität der Zwangskonvektion durch relative Abstimmung voneinander unabhängig einstellbarer Parameter wie Verweilzeit des Walzgutes (1) beim Durchlauf durch den Druckraum (10) und durch den Konvektionsraum (13) sowie Menge, Druck und Strömungsgeschwindigkeit des Kühlmediums gesteuert und von diesem Wärme aus dem Walzgut (1) bevorzugt bis zu einem Sicherheitsabstand zum Siedepunkt zur Vermeidung der instabilen Filmverdampfung aufgenommen wird. Die Erfindung beschreibt auch eine Vorrichtung zur Durchführung des Verfahrens.
