ÜBERSETZUNG PatentansprücheTRANSLATION Claims 1. Kühlvorrichtung zum schnellen und gezielten Abkühlen eines Metallstreifens in einem Glühofen mit neutraler oder reduzierender Atmosphäre, welche eine Reihe von Walzen aufweist, welche durch Umlauf einer Flüssigkeit gekühlt sind und über welche der Metallstreifen unter Aufliegen kontinuierlich abläuft, dadurch GEKENNZEICHNET, daß die Walzen (14) eine feste Stellung aufweisen, so daß die Länge des vom Metallstreifen (10) auf den Walzen beschriebenen Aufrollbogens während der Kühlung nicht veränderbar ist, und daß gegenüber jeder Walze eine Gasstrahl-Blaseinrichtung vorgesehen ist, welche einen Gasstrahl (2G) senkrecht zum Metallstreifen aufbläst.1. Cooling device for rapid and targeted cooling of a metal strip in an annealing furnace with a neutral or reducing atmosphere, which comprises a series of rollers, which by circulation of a liquid are cooled and over which the metal strip is under Laying on runs continuously, CHARACTERIZED in that the rollers (14) have a fixed position, so that the length of the metal strip (10) on the rollers described roll-up arch during cooling is changeable, and that opposite each roller a gas jet blowing device is provided, which inflates a gas jet (2G) perpendicular to the metal strip. 2. Kühlvorrichtung nach Anspruch 1, dadurch GEKENNZEICHNET, daß die Blaseinrichtung aus Kästen (18) besteht, welche mit Blasstutzen bzw. Blasschlitzen versehen sind.2. Cooling device according to claim 1, characterized in that the blowing device consists of boxes (18) which are provided with blow nozzles or blow slots. 3. Kühlvorrichtung nach Anspruch 2, dadurch GEKENNZEICHNET, daß das auf den Metallstreifen aufgeblasene Gas zur Weiterleitung in einen Wärmetauscher (24) auffangbar ist, ehe es in die Kästen (18) mittels eines Umwälzgebläses (26) rückgeführt wird.3. Cooling device according to claim 2, characterized in that the gas inflated on the metal strip for Forwarding into a heat exchanger (24) can be collected before it enters the boxes (18) by means of a circulating fan (26) is returned. 4. Kühlvorrichtung nach einem der vorhergehenden Ansprüche, dadurch GEKENNZEICHNET, daß die Regelung der Endtemperatur des Metallstreifens (10) beim Austritt aus der Vorrichtung dadurch sichergestellt ist, daß die Geschwindigkeit der den Metallstreifen überstreichenden Gasstrahlen (20) veränderbar ist.4. Cooling device according to one of the preceding claims, CHARACTERIZED in that the regulation of the final temperature of the metal strip (10) upon exit from the Device is ensured by the fact that the speed of the gas jets sweeping over the metal strip (20) is changeable. 5. Kühlvorrichtung nach einem der vorhergehenden Ansprüche, dadurch GEKENNZEICHNET, daß in jedem gewünschten Verhältnis ein Schutzgas in der Gasstrahl-Einblasanlage verwendbar ist.5. Cooling device according to one of the preceding claims, characterized in that in any desired Ratio a protective gas in the gas jet injection system can be used.
