Description
Die Erfindung betrifft einen gekühlten Hohldorn, dessen doppelte Wand von Kühlwasser durchflossen ist und der an seinem oberen Ende mit einer Zuführung und einer Ableitung für das Kühlwasser versehen ist.The invention relates to a cooled hollow mandrel, the double wall of which is traversed by cooling water is and which is provided at its upper end with a supply and a discharge line for the cooling water is.
Ein derartiger Hohldorn ist beispielsweise aus der deutschen Patentschrift 1099 700 bekannt.Such a hollow mandrel is known from German patent specification 1099 700, for example.
Die Aufgabe der Erfindung besteht darin, einen gekühlten Hohldorn zu schaffen, der einen vergrößerten Hohlraum im Inneren aufweist und der dennoch eine gute Kühlleistung aufweist.The object of the invention is to provide a cooled hollow mandrel that has an enlarged Has a cavity inside and which nevertheless has a good cooling performance.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß der Zwischenraum innerhalb der Wand des Hohldornes durch senkrechte, in radialer Riehtang verlaufende Stege in Kanäle aufgeteilt ist, und zwar so, daß jeweils zwei benachbarte Kanäle am unteren Ende des Hohldornes miteinander verbunden sind, wobei der eine Kanal an die Zuführung und der andere Kanal an die Ableitung für das Kühlwasser angeschlossen ist.This object is achieved according to the invention in that the space within the wall of the hollow mandrel is divided into channels by vertical webs running in a radial direction, and so that in each case two adjacent channels are connected to one another at the lower end of the hollow mandrel are, with one channel connected to the supply and the other channel to the discharge line for the cooling water is.
Die Kühlmittelführung ist bei dem erfindungsgemäßen Hohldorn auf engem Raum zusammengedrängt, so daß bei gleichzeitiger Verbesserung der Kühlwirkung ein erheblich vergrößerter freier Querschnitt des Hohldornes erreicht worden ist.In the hollow mandrel according to the invention, the coolant flow is compressed into a small space, so that with a simultaneous improvement of the cooling effect a considerably larger free cross-section of the hollow mandrel has been reached.
Die Erfindung soll an Hand der Zeichnung näher erläutert werden; dabei zeigtThe invention will be explained in more detail with reference to the drawing; thereby shows
F i g. 1 den Hohldorn schematisch im Schnitt,F i g. 1 the hollow mandrel schematically in section,
Fig.2 einen Schnitt gemäß der Linie A-B nach Fig.l,2 shows a section along the line AB according to FIG.
F i g. 3 eine Abwicklung nach F i g. 2.F i g. 3 a settlement according to FIG. 2.
Wie in den Fig.l bis 3 näher dargestellt, hat der Hohldorn 2 eine äußere, dem Gießwerkstoff bzw. dem Strang zugewandte Wand 9 und eine innere Wand 10, zwischen denen Kanäle 11,12 zur Führung des Kühlwassers angeordnet sind. Die einzelnen Kanäle 11, 12 sind durch senkrechte, in radialer Richtung verlaufende Stege 13 voneinander getrennt. Wie in F i g. 3 gezeigt, sind jeweils zwei benachbarte Kanäle 11, 12 am unteren Ende des Hohldornes miteinander verbunden. Außerdem ist der Kanal 11 an die Zuführung 15 und der Kanal 12 an die Ableitung 14 des Kühlwassers angeschlossen.As shown in more detail in Fig.l to 3, the Hollow mandrel 2, an outer wall 9 facing the casting material or the strand, and an inner wall 10, between which channels 11, 12 are arranged for guiding the cooling water. The individual channels 11, 12 are separated from one another by vertical webs 13 running in the radial direction. As in Fig. 3 shown, two adjacent channels 11, 12 are connected to one another at the lower end of the hollow mandrel. In addition, the channel 11 is to the feed 15 and the channel 12 to the discharge line 14 of the cooling water connected.
Die Führung des Kühlwassers in dem Hohldorn gemäß der vorliegenden Erfindung bietet den Vorteil, daß sie auf einen engen Raum zusammengedrängt ist und einen möglichst großen ireien Querschnitt im Inneren des Hohldornes übrigläßt.The guidance of the cooling water in the hollow mandrel according to the present invention offers the advantage that it is compressed into a narrow space and the largest possible internal cross-section of the hollow mandrel.
Mit 4 ist die Spritzwasserleitung und mit 6 und 7 die Abführung für den entstehenden Wasserdampf bezeichnet.With 4 is the spray water line and with 6 and 7 the discharge for the resulting water vapor designated.
