Abstract

A plant that cools an incandescently-hot plate-, strip- or loose material (4) conveyed continuously. The plant comprises zones (1, 2, 3) with impinging air or gas coolant jet flows, supplied by blowers (7, 8) via nozzle registers (10). A special feature is connection of only the last zone (3) to the fresh supply (7) of coolant under pressure. After jet formation and contact with the material, collection fans (8) then force the coolant into a distribution chest (9, 12) connected to further nozzle registers (10). Further, like arrangements follow, up to the first (hottest) zone of incandescent material; only then does the final collection fan (13) discharge into the open air. Preferably, both upper and lower cooling zones are provided, with further collection fans and registers for recirculation from the lower zone.

Description

Die Erfindung bezieht sich auf eine Kühlanlage für auf einer Transporteinrichtung kontinuierlich bewegtes Glühgut in Form von Platten, Bändern oder Schüttgut, wobei die Kühlanlage aus mehreren Zonen besteht, in denen das Glühgut an seiner Unter- und/oder Oberseite mit aus Düsen von durch Verdichtergebläse gespeisten Düsenbalken austretenden Kühlmedium-Prallstrahlen aus Luft oder Gas behandelt wird.The invention relates to a cooling system for annealing material moving continuously on a transport device in the form of plates, strips or bulk material, the cooling system consisting of several zones in which the annealing material on its underside and / or top side is fed with nozzles by compressor blowers Nozzle bar emerging coolant impingement jets from air or gas is treated.

Prallstrahlen haben ein sehr hohes Wärmeübertragungsvermögen, wobei Gas als Schutzgas dann verwendet wird, wenn eine unerwünschte Oxidation vermieden werden soll. Bisher weist jede der hintereinander angeordneten Anlagezonen für die Bildung der Prallstrahlen ein eigenes Verdichtungsgebläse auf, ebenso wie je ein eigenes Absauggebläse ins Freie vorgesehen ist. Beispielsweise werden zum Abkühlen von Leichtmetallplatten in drei Anlagezonen etwa je 15 000 m3/h Luft mit einer Temperatur von etwa 30 °C zugeführt, wobei die Luft durch den Wärmetausch mit dem Glühgut um etwa 10 - 15 °C erwärmt und dann ins Freie abgeführt wird. Da also jede Anlagenzone mit Frischluft versorgt werden muß, ergibt sich ein verhältnismäßig hoher Kühlmediumverbrauch, wobei auch der vorrichtungsmäßige Aufwand entsprechend hoch ist.Impact jets have a very high heat transfer capacity, whereby gas is used as a protective gas when undesired oxidation is to be avoided. So far, each of the contact zones arranged one behind the other has its own compression blower for the formation of the impact jets, just as a separate suction blower is provided outdoors. For example, about 15,000 m 3 / h of air at a temperature of about 30 ° C are supplied in three plant zones for cooling light metal plates, the air being heated by about 10 - 15 ° C by the heat exchange with the annealing material and then discharged outdoors becomes. Since every plant zone must be supplied with fresh air, the cooling medium consumption is relatively high, and the expenditure on the device is correspondingly high.

Somit liegt der Erfindung die Aufgabe zugrunde, diese Mängel zu beseitigen und die eingangs geschilderte Kühlanlage so zu verbessern, daß eine wesentlich verminderte Zufuhr von frischem Kühlmedium erforderlich ist und sich auch der technische Aufwand verringert.The invention is therefore based on the object of eliminating these deficiencies and improving the cooling system described at the outset in such a way that a substantially reduced supply of fresh cooling medium is required and the technical outlay is also reduced.

Die Erfindung löst die gestellte Aufgabe dadurch, daß nur die letzte, für das Glühgut austrittsseitige Anlagenzone an die Zufuhr des unter Druck stehenden frischen Kühlmediums angeschlossen und für das Kühlmedium nach Bildung der Prallstrahlen ein Sammelventilator vorgesehen ist, der das Kühlmedium in einen Verteilerkasten drückt, an den die Düsenbalken der vorletzten Anlagenzone angeschlossen sind, die ebenfalls einen Sammelventilator mit Verteilerkasten für die ihr vorgeordnete Anlagenzone besitzt, wobei sich diese Anordnung bzw. Einrichtung bis zur ersten für das Glühgut eintrittsseitigen Anlagenzone wiederholt, deren Sammelventilator erst ins Freie mündet.The invention solves this problem in that only the last plant zone on the outlet side for the annealing material is connected to the supply of the pressurized fresh cooling medium and a collecting fan is provided for the cooling medium after the impingement jets have been formed, which presses the cooling medium into a distribution box which are connected to the nozzle bars of the penultimate plant zone, which also has a collecting fan with a distribution box for the plant zone upstream of it, this arrangement or arrangement being repeated up to the first plant zone on the inlet side for the annealing material, the collecting fan only opening into the open.

Da also nur die letzte, für das Glühgut austrittsseitige Anlagenzone mit frischem Kühlmedium zu versorgen ist, das bis zur ersten Anlagenzone unter entsprechendem jeweiligem Energieaustausch durchgedrückt wird, ergibt sich die gewünschte beträchtliche Verringerung der erforderlichen Glühgutmenge, wobei sich in jeder Anlagenzone die Temperatur des Kühlmittels um etwa 10 - 15 °C erhöht, ohne daß der gesamte Kühleffekt vermindert wird. Da die Absaugventilatoren je nach der Anzahl der Anlagenzonen zugleich die Kühlmittelspeisung der jeweils vorgeordneten Anlagenzone bilden, wird auch eine entsprechende Verminderung des gesamten technischen Aufwandes erzielt.Since only the last plant zone on the outlet side for the annealing material has to be supplied with fresh cooling medium, which is pushed through to the first system zone with the corresponding energy exchange, the desired considerable reduction in the quantity of annealing material required results, with the temperature of the coolant in each system zone about 10 - 15 ° C without reducing the overall cooling effect. Since, depending on the number of system zones, the exhaust fans also form the coolant supply to the upstream system zone, a corresponding reduction in the overall technical effort is also achieved.

Handelt es sich um eine Kühlanlage, bei der das Glühgut an seiner Ober- und Unterseite gekühlt wird und in der betreffenden Anlagenzone untere und obere Düsenbalken vorgesehen sind, ist erfindungsgemäß jeweils der untere Düsenbalken mit dem Verteilerkasten aus der in Transportrichtung des Glühgutes folgenden Anlagenzone bzw. mit der Zufuhr für das frische Kühlmedium verbunden und es ist ein zusätzlicher Sammelventilator vorgesehen, der das aus dem unteren Düsenbalken stammende Kühlmedium in den oberen Düsenbalken drückt. Selbstverständlich muß dann für die ganze Anlagenzone noch ein Absaugventilator zur Förderung des Kühlmediums durch den Verteilerkasten unter Druck in die vorgeordnete Anlagenzone vorgesehen sein.If it is a cooling system in which the annealing material is cooled on its upper and lower sides and lower and upper nozzle bars are provided in the relevant system zone, the lower nozzle bar with the distribution box is, according to the invention, from the system zone following in the transport direction of the annealing material or connected to the supply for the fresh cooling medium and an additional collecting fan is provided, which presses the cooling medium originating from the lower nozzle bar into the upper nozzle bar. Of course, a suction fan for conveying the cooling medium through the distribution box under pressure into the upstream system zone must then be provided for the entire system zone.

Gemäß Fig. 1 besteht die Kühlanlage aus drei Zonen 1, 2, 3, durch die das Kühlgut 4 in Plattenform auf einer aus Antriebsrollen 5 bestehenden Transporteinrichtung (Fig. 2) kontinuierlich im Sinne der Pfeile 6 bewegt wird. Als Kühlmedium dient Kaltluft, die über einen Ventilator 7 in die letzte, also für das Glühgut 4 austrittsseitige Anlagenzone 3 drückt. Diese ist mit einem Sammelventilator 8 versehen, der das Kühlmedium in einen Verteilerkasten 9 drückt, an den Düsenbalken 10 zur Bildung von auf das Glühgut 4 wirkenden Prallstrahlen angeschlossen sind. Die Anlagenzone 2 weist ebenfalls einen Sammelventilator 11 mit Verteilerkasten 12 für die eintrittsseitige erste Anlagenzone 1 auf, von der erst ein Sammelventilator 13 ins Freie führt.1, the cooling system consists of three zones 1, 2, 3, through which the refrigerated goods 4 in plate form on a transport device consisting of drive rollers 5 (FIG. 2) are moved continuously in the direction of arrows 6. Cold air is used as the cooling medium, which presses via a fan 7 into the last plant zone 3, that is to say on the outlet side for the annealing material 4. This is provided with a collecting fan 8, which presses the cooling medium into a distribution box 9, to which nozzle bars 10 are connected to form impingement jets acting on the annealing material 4. The plant zone 2 also has a collecting fan 11 with a distribution box 12 for the inlet-side first plant zone 1, from which only a collecting fan 13 leads outside.

Gemäß Fig. 2 handelt es sich um eine Kühlanlage, bei der das Glühgut 4 auf den Antriebswalzen 5 an seiner Unter- und Oberseite gekühlt wird. Das Kühlmedium kommt aus einem Verteiler 9a der in Transportrichtung nachgeordneten Anlagenzone in einen unteren Düsenbalken 10a und wird von einem zusätzlichen Sammelventilator 8a über einen Verteilerkasten 9a dem oberen Düsenbalken 10b zugeleitet. Beide Düsenbalken 10a, 10b sind selbstverständlich mit Pralldüsen versehen. Das vom Düsenbalken 10b austretende Kühlmedium wird nach seiner Prallwirkung über einen Ansaugventilator 8 und den Verteilerkasten 9 der vorgeordneten Anlagenzone zugeführt.2, it is a cooling system in which the annealing material 4 is cooled on the drive rollers 5 on its top and bottom. The cooling medium comes from a distributor 9a of the plant zone downstream in the direction of transport into a lower nozzle bar 10a and is fed to the upper nozzle bar 10b by an additional collecting fan 8a via a distributor box 9a. Both nozzle bars 10a, 10b are of course provided with impact nozzles. The cooling medium emerging from the nozzle bar 10b is fed to the upstream system zone via its suction effect via a suction fan 8 and the distribution box 9.
