Description

Kühlzone für Durchlauföfen mit Hubbalkenförderung Bei Durchlauföfen mit Hubbalkenförderung kann es notwendig werden, die durch den Ofen wandernden Gegenstände aus Eisen oder anderem Metall nach der Erwärmung auf eine Temperatur von beispielsweise 95o° C plötzlich auf ungefähr 65o° C abzukühlen. Im allgemeinen wird dies dadurch erzielt, daß die Gewölbedecke der an den Ofen angeschlossenen Kühlzone mit Wasser oder Luft gekühlt wird, oder aber daß eine bewegliche Decke vorhanden ist; die über dem Glühgut aufgehängt ist und dem Glühgut genähert bzw. von ihm entfernt werden kann. Die Kühlung des Glühgutes erfolgt in diesen Fällen also nur von oben, da die Kühlung von unten bei Hubbalkenförderung ziemlich schwierig auszubilden ist. Es sind Ausführungen bekannt, bei welchen die Hubbalken mit Wasser oder Luft gekühlt werden. Diese Art der Kühlung hat jedoch den Nachteil, da.ß keine scharfe Abgrenzung der Kühlzone erreicht wird. Da die Hubbalken sich in der waagerechten Richtung vorwärts und rückwärts bewegen, verschiebt sich der Beginn der Kühlzone um die Hublänge der Balken. Außerdem ergibt sich infolge der Auf- und Abwärtsbewegung der gekühlten Hubbalken auch in der senkrechten Richtung eine Unregelmäßigkeit in der Kühlwirkung, da jeweils das eine Balkenpaar unmittelbar unter dem Glühgut liegt, während das andere sich in einem gewissen Abstand unterhalb des Glühgutes befindet.Cooling zone for continuous ovens with walking beam conveyor For continuous ovens With walking beam conveying it may be necessary to move objects through the furnace of iron or other metal after heating to a temperature of, for example 95o ° C suddenly cool down to around 65o ° C. In general, this will be the result achieved that the vaulted ceiling of the cooling zone connected to the furnace with water or air is cooled, or that there is a movable ceiling; the above the material to be annealed is suspended and to be approached or removed from the material to be annealed can. In these cases, the annealing material is only cooled from above, since the Cooling from below with walking beam conveyance is quite difficult to train. It Designs are known in which the walking beam is cooled with water or air will. However, this type of cooling has the disadvantage that there is no sharp delimitation the cooling zone is reached. As the walking beam moves forward in the horizontal direction and move backwards, the start of the cooling zone is shifted by the stroke length of the Bar. In addition, as a result of the upward and downward movement of the cooled The lifting beam also shows an irregularity in the cooling effect in the vertical direction, since one pair of bars is located directly below the annealing material, while the other is at a certain distance below the annealing material.

Die Erfindung betrifft eine Kühlvorrichtung, welche unterhalb des Glühgutes vollkommen unabhängig von den Hubbalken vorgesehen ist. Hierdurch werden die Nachteile, welche sich durch Verschiebung der gekühlten Hubbalken in der -waagerechten und senkrechten Richtung ergeben, vermieden. Das Glühgut befindet sich also stets im gleichen Abstand von der Kühlvorrichtung. Außerdem ist der Beginn der Kühlzone beim Durchlauf des Glühgutes scharf abgegrenzt, wodurch eine außerordentlich gleichmäßige Kühlwirkung erzielt wird. In der Zeichnung ist eine beispielsweise Ausführung der Kühlvorrichtung dargestellt, und zwar in Abb. i im Längsschnitt und in Abb, z im Querschnitt.The invention relates to a cooling device which is below the Annealing material is provided completely independently of the walking beam. This will be the disadvantages, which are caused by shifting the cooled walking beam in the horizontal and vertical direction are avoided. The annealing material is always there at the same distance from the cooling device. It is also the start of the cooling zone sharply demarcated when the annealing material passes through, creating an extraordinarily uniform Cooling effect is achieved. The drawing shows an example of an embodiment of the Cooling device shown, in Fig. I in longitudinal section and in Fig, z im Cross-section.

Das Glühgut wird durch zwei bewegliche Hubbalkengruppen a und b umunterbrochen vorwärts bewegt. Die einzelnen Hubbalken besitzen in ihrem oberen Teil Aussparungen c, so daß sich ein freier Zwischenraum über die ganze Ofenbreite bildet. In diesem Raum liegt die in den Ofenseit.enwänden befestigte oder beweglich aufgehängte Kühlvorrichtung d. Der Zulauf des Kühlmittels, welches Wasser oder Luft sein kann, erfolgt bei e und der Ablauf bei f.The annealing material is broken up by two movable groups of walking beams a and b moved forward. The individual lifting beams have recesses in their upper part c, so that a free space is formed over the entire width of the furnace. In this The cooling device, which is attached or movably suspended in the furnace side walls, is located in the space d. The coolant, which can be water or air, is fed in at e and the process at f.
