   Dies kann in der verschiedensten Weise durch entsprechende Ausbildung des Hahnkegels erreicht werden. Als Beispiel ist in der Fig. 1 angenommen worden, dass der eine Kegelkanal, der mit der Leitung   Og   die   Verbindung herstellt, etwas schräg gerichtet ist.

 EMI2.1
 Mixing channel is admitted, but if the oxygen is admitted to the cutting jet, the oxygen supply to the mixing jet is reduced.



   This can be achieved in various ways by appropriate design of the cock plug. As an example, it has been assumed in FIG. 1 that the one conical channel which establishes the connection with the line Og is directed somewhat obliquely.



   PATENT CLAIMS:
1. A method for cutting metals by means of an oxygen jet using a gas-oxygen mixed jet supplied through special bores for preheating and warming, characterized in that for the first preheating before cutting this mixing

Claims (1)

dass der Übergang von der einen zur anderen Betriebsweise durch das Umlegen eines einzigen Schaltorganes bewirkt wird, derart, dass in der einen Stellung (Vorwärmen) die An-und Vor- wunnphohrung mit einer sauerstoffreichen Gasmischung, in der anderen Stellung (Schneiden mit gleichzeitigem Anwärmen) die An-und Vorwärmebohrung mit einer sauerstoffärmeren Gasmischung und die Schneidbohrung mit Sauerstoff beschickt wird. that the transition from one mode of operation to the other is effected by flipping a single switching element, in such a way that in one position (preheating) the inlet and outlet pipes with an oxygen-rich gas mixture, in the other position (cutting with simultaneous heating) the warm-up and preheating hole is charged with a gas mixture that is less oxygenated and the cutting hole is charged with oxygen.
