Abstract

Bei einem derartigen Kühlverfahren für langgestrecktes, heißes Metallgut, insbesondere für stranggegossene Knüp­ pel- bzw. Bloomstränge aus Stahl, erfolgt eine gesteuerte Wärmeabfuhr durch Aufsprühen eines oder mehrerer Medien. Beim Stranggießen wird einerseits eine schnelle Strangschalenbildung zur Festigung des im Inneren noch flüssigen Stranges angestrebt, und andererseits sollen bestimmte Gefügeeigenschaften erzielt werden. In such a cooling process for elongated, hot metal goods, especially for continuous cast knots pel or Bloom strands made of steel, a controlled Heat dissipation by spraying on one or more Media. On the one hand, continuous casting is quick Strand shell formation for strengthening the inside aspired liquid strand, and on the other hand should certain structural properties can be achieved.

Gemäß dem Stand der Technik ist bei einer solchen Spritzkühlung der zur Oberfläche des zu kühlenden Körpers senkrecht gerichtete Impuls der Kühlflüssigkeit merklich größer als der Impuls bei einer parallel zur Oberfläche anströmenden Kühlflüssigkeit. Diese Technik hat eine oft schroffe Kühlung von kreis- oder ellipsenförmigen Bereichen der Metallgut-Oberfläche zur Folge. According to the prior art, such Spray cooling to the surface of the body to be cooled vertically directed pulse of the coolant noticeable greater than the momentum of a parallel to the surface incoming coolant. This technique often has one abrupt cooling of circular or elliptical areas the metal surface.

Zur Vermeidung dieser Schwierigkeiten wird vorge­ schlagen, daß das Kühlmedium bzw. die Kühlmedien in Sprühstrahlen parallel zur Metallgut-Längsachse aufge­ bracht werden und daß jeder Sprühstrahl von der Düsenöff­ nung ausgehend entsprechend der von der Düse aus Druckenergie in Geschwindigkeitsenergie umgewandelten Sprühstralgeschwindigkeit derart der Metallgut-Oberfläche angenähert wird, daß mit einer höheren Sprühstrahlge­ schwindigkeit ein kleinerer Neigungswinkel und mit einer geringeren Sprühstrahlgeschwindigkeit ein größerer Nei­ gungswinkel zur Metallgut-Oberfläche verbunden ist. To avoid these difficulties is pre suggest that the cooling medium or the cooling media in Spray jets set up parallel to the longitudinal axis of the metal goods be brought and that each spray jet from the nozzle opening starting from the nozzle Converted pressure energy into speed energy Spray wire speed of the metal surface is approximated that with a higher spray jet speed a smaller angle of inclination and with a lower spray jet speed a larger Nei angle to the metal surface is connected.
