Definitions
- aqueous baths Methods using aqueous baths are also known. During the immersion in such a water bath, laminar flow, non-turbulent, a vapor film is formed around the son to be cooled (see, for example, EP-A-0 216 434 ). This vapor film is thermally insulating, so it slows down the cooling
- Current running drive means are shown schematically by references 23 and 24.
- the water can be supplied by an inlet 5 and be evacuated from the top by an overflow 6. In the illustrated tank the height of water column is equal to about 750mm H 2 O (7350 Pa).
- the overflow 6 may be in communication with a lower inlet 5 ', through a not shown heat exchanger, so as to put the cooling water in circulation.

Claims (9)
- Verfahren zum Patentieren mindestens eines Stahldrahts, wobei das Verfahren Folgendes umfasst:- ein Erhöhen der Temperatur des mindestens eines Stahldrahts auf eine Austenisierungstemperatur des Stahls,- ein abruptes Abkühlen des mindestens einen Drahts, der die Austenisierungstemperatur erreicht hat, in flüssigem Medium durch Führen des mindestens eines Drahts durch mindestens einen Vorhang der Abkühlungsflüssigkeit, wobei dieser eine Wirbelströmung aufweist, die im Wesentlichen quer auf den mindestens einen geführten Draht ausgerichtet ist, unter Erreichen einer Abkühlungstemperatur, die unter der Austenisierungstemperatur und über einer martensitischen Transformationstemperatur liegt und- ein isothermes Halten des mindestens einen Stahldrahts auf einer perlitischen Transformationstemperatur bis zum Abschluss dieser Transformation,
dadurch gekennzeichnet, dass das Verfahren außerdem Folgendes umfasst:- ein Injizieren von unter Druck stehenden Glasblasen in eine Abkühlungsflüssigkeitsmasse auf nach oben gerichtete Weise und ein Mitreißen der Flüssigkeit durch die Blasen in der Form von Vorhängen, die von einem unteren Teil aus gemäß einer aufsteigenden Wirbelströmung gesprüht werden,- ein Einstellen einer Anzahl der oben genannten aufeinander folgenden Vorhänge, die bestimmt wird, um durch das Abkühlen in flüssigem Medium die perlitische Transformationstemperatur, die während des Schritts des isothermen Haltens gehalten werden soll, mit der oben genannten Abkühlungstemperatur zu erzielen, und- das oben genannte isotherme Halten direkt nach dem Abkühlen in flüssigem Medium. - Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Vorhänge mit aufsteigender Wirbelströmung einen oberen Teil aufweisen und dass das Verfahren außerdem einen Fall der Flüssigkeit mit Wirbelströmung von dem oberen Teil und mindestens einer Seite jedes Vorhangs mit aufsteigender Wirbelströmung aus umfasst, durch die auch der mindestens eine Stahldraht geführt wird.
- Verfahren nach Anspruch 2, dadurch gekennzeichnet, dass die oben genannten Fälle der Flüssigkeit mit Wirbelströmung, die vom oberen Teil der oben genannten zwei aufeinander folgenden Vorhänge ausgeht, sich zumindest zum Teil dort kreuzen, wo der mindestens eine Stahldraht geführt wird.
- Verfahren nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die Abkühlungsflüssigkeit Wasser ist.
- Verfahren nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die zu patentierenden Drähte einen Querschnitt mit einem Durchmesser von weniger als 15 mm aufweisen.

und- eine Kammer zum Halten der Temperatur (31) für die Drähte, die die perlitische Transformationstemperatur erreicht haben,
dadurch gekennzeichnet, dass die Vorrichtung außerdem Folgendes umfasst:- einen Tank (1), der die Abkühlungsflüssigkeit enthält und der unter dem mindestens einen geführten Draht (3; 26) angeordnet ist,- Mittel zum Sprühen (7 - 9, 14, 15, 16) der oben genannten Vorhänge, die von dem Tank aus gemäß einer aufsteigenden Wirbelströmung gesprüht werden, durch Injizieren von unter Druck stehenden Gasblasen in die Abkühlungsflüssigkeit auf nach oben gerichtete Weise,- Mittel zum Einstellen (22) der Anzahl der aufeinander folgenden Vorhänge der Abkühlungsflüssigkeit, durch die der mindestens eine geführte Draht laufen soll, um die perlitische Transformationstemperatur mit der Abkühlungstemperatur zu erzielen, und- eine Anordnung der Kammer zum Halten der Temperatur direkt am Austritt des Vorhangs, der sich in Bezug auf das Führen des mindestens einen Drahts am weitesten stromabwärts befindet. - Vorrichtung nach Anspruch 7, dadurch gekennzeichnet, dass sie außerdem über dem mindestens einen geführten Draht Umlenkmittel (20, 21) umfasst, die die aufsteigende Wirbelströmung der oben genannten Flüssigkeitsvorhänge in Richtung mindestens einer Seite jedes Vorhangs ablenken, um daraus mindestens einen Fall der Flüssigkeit mit Wirbelströmung zu bilden, durch den der mindestens eine Stahldraht geführt wird.
- Vorrichtung nach einem der Ansprüche 7 und 8, dadurch gekennzeichnet, dass die Kammer zum Halten der Temperatur (31) derart montiert ist, dass sie horizontal über den Tank (1) entsprechend der Anzahl der Flüssigkeitsvorhänge im Betrieb bewegt werden kann.
