Abstract

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Abkühlen von durch Warmverformen erzeugten metallischen Langprodukten, insbesondere Spundbohlen (S,S1) aus Stahl, bei dem in einem ersten Schritt die Langprodukte (S,S1) zunächst über ein Kühlzeitintervall (K1 - K5) durch Benetzen mit einem Kühlfluid um eine Temperaturdifferenz (ΔT1 - ΔT5) abgekühlt werden und bei dem in einem zweiten Schritt über ein Ausgleichszeitintervall (E1 - E4) ohne die Einwirkung eines Kühlmittels ein Temperaturausgleich in dem Langprodukt (S,S1) hergestellt wird, wobei die Schritte der stufenweisen Abkühlung und des Temperaturausgleichs wiederholt werden, bis eine Soll-Endtemperatur (ET) in dem Langprodukt (S,S1) erreicht ist. Das erfindungsgemäße Verfahren und die Vorrichtung ermöglichen es, Langprodukte, insbesondere Spundbohlen, auf kostengünstige Weise ohne die Gefahr einer ungewollten Verformung abkühlen zu lassen.

The present invention relates to a method and a device for cooling metal long products produced by hot forming, in particular sheet piles (S, S1) made of steel, in which, in a first step, the long products (S, S1) initially over a cooling time interval (K1 - K5) are cooled by wetting with a cooling fluid by a temperature difference (ΔT1 - ΔT5) and in which in a second step over a compensation time interval (E1 - E4) without the action of a coolant, a temperature compensation is produced in the long product (S, S1), the Steps of gradual cooling and temperature compensation are repeated until a target end temperature (ET) in the long product (S, S1) is reached. The method and the device according to the invention enable long products, in particular sheet piles, to be cooled in a cost-effective manner without the risk of undesired deformation.
