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.
