Description

Schneidbrenner Nach dem Hauptpatent 731 175 soll ein Schneidbrenner, dessen Sauerstoffdüse von einer in geringem Abstand angeordneten, schmalen ringförmigen Brenngasdüse umgeben ist, so ausgebildet sein, daß die Sauerstoffdüse etwa halbkreisförmigen Querschnitt besitzt, während die Brenngasdüse einenbalbrin:gförmigen oder wirkungsähnlichen Querschnitt aufweist, so, daß der Schnittfuge abgewandte Teile der Flamme und des Sauerstoffstrahles in-Fortfall kommen.Cutting torch According to the main patent 731 175 , a cutting torch, the oxygen nozzle of which is surrounded by a narrow, annular fuel gas nozzle arranged at a short distance, should be designed in such a way that the oxygen nozzle has an approximately semicircular cross-section, while the fuel gas nozzle has a spherical cross-section that is shaped like or similar in effect, that the kerf facing away from parts of the flame and the oxygen jet come in -fall.

Derselbe Erfindungsgedanke läßt sich auch übertragen auf solche Schneidbrenner, bei welchen die Brenngasdüse und die Sauerstoffdüse hintereinander angeordnet sind. Beide Düsen ;erbalten dann einen etwa halbkreisfärmigen Querschnitt, um auf diese Weise für den Sebneidvorgang unwirksame bzw. weniger wirksame Anteile der Brenngase und des Sehneidsauerstoffes zu .ersparen. Untersuchungen haben ergeben, daß auch in diesem Falle bei Benutzung der Spardüsen um etwa 3o bis 4o% geringere Mengen ,an Sauerstoff und Heizgas benötigt werden als bei der Verwendung einer Normaldüse unter sonst gleichbleibenden Bedingungen, wie gleicher Blechdicke, gleichbleibender Schnittgeschwindigkeit und gleichem Druck.The same idea of the invention can also be applied to such cutting torches, in which the fuel gas nozzle and the oxygen nozzle are arranged one behind the other. Both nozzles; then developed an approximately semicircular cross-section to access them Way for the Sebneidvorgang ineffective or less effective components of the fuel gases and to save the tendon oxygen. Research has shown that too In this case, when using the economy nozzles, the quantities are about 3o to 4o% lower , oxygen and heating gas are required than when using a normal nozzle under otherwise constant conditions, such as the same sheet thickness, more constant Cutting speed and the same pressure.
