  Strahlvorrichtung zum Abkühlen von metallurgischen Apparaten 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
AuskleidungPressluftdüse 3, der nach einer kurzen Strecke 4 folgenden Erweiterung 5 und der Leitung 6 für die geförderte Mischung von Pressluft und Aussenluft. Die Teile 2,3, 4 und 5 bilden solcherart einen Injektor, mit dessen Wirkung durch das Ansaugrohr 1 Aussenluft angesaugt und durch das Rohr 6 der Verwendungsstelle im zu kühlenden metallurgischen Apparat zugeführt wird. Bei Verwendung der Vorrichtung zur Abkühlung der feuerfesten Zustellung eines Konverters wird sie derart angeordnet, dass das Ansaugrohr ausserhalb des Konverters liegt, während das Ende des Rohres 6 nahe dem Konverterboden liegt.

   Bevorzugte Abmessungen der Vorrichtung sind die folgenden : Bei einem Durchmesser D der Leitung 6 soll das Ansaugrohr 1 einen Durchmesser gleich 1 1/2 D, das enge Mittelstück (Venturirohr) 1/2 D und die   Pressluftdüse   für Drucke höher als 3 atü eine Öffnung gleich 1/19 D aufweisen, wobei die Länge der Verengung 2 2 1/2 D, des Venturirohres 4   11/4   D und der Erweiterung 5 4 1/2 D betragen soll. 



     PATENTANSPRÜCHE   : 
1. Verwendung einer Strahlvorrichtung mit einem Ansaugrohr für Aussenluft, einer Injektoreinrichtung mit   Pressluftdüse   vor einer entsprechend dimensionierten Verengung und einer daran anschliessenden Erweiterung sowie einem daran anschliessenden Förderrohr zur Abkühlung von metallurgischen Apparaten vor oder während Reparaturarbeiten oder für   Ausbruchs-und Neuzustellungsarbeiten.

  Blasting device for cooling down metallurgical equipment
 EMI1.1
 

 <Desc / Clms Page number 2>

 
Lining the compressed air nozzle 3, the extension 5 following a short distance 4 and the line 6 for the conveyed mixture of compressed air and outside air. The parts 2, 3, 4 and 5 thus form an injector, with the effect of which outside air is sucked in through the intake pipe 1 and fed through the pipe 6 to the point of use in the metallurgical apparatus to be cooled. When using the device for cooling the refractory lining of a converter, it is arranged in such a way that the suction pipe is outside the converter, while the end of the pipe 6 is close to the converter base.

   Preferred dimensions of the device are as follows: With a diameter D of the line 6, the suction tube 1 should have a diameter equal to 1 1/2 D, the narrow center piece (Venturi tube) 1/2 D and the compressed air nozzle for pressures higher than 3 atmospheres should have an opening 1/19 D, the length of the constriction should be 2 2 1/2 D, the Venturi tube 4 11/4 D and the extension 5 4 1/2 D.



     PATENT CLAIMS:
1. Use of a blasting device with a suction pipe for outside air, an injector device with a compressed air nozzle in front of a correspondingly dimensioned constriction and an adjoining extension as well as an adjoining conveying pipe for cooling down metallurgical apparatus before or during repair work or for excavation and relining work.
