Abstract

  • 2.1 Die im Verschleißfutter des metallurgischen Gefäßes angeordneten, als Spüleinrichtung dienenden bekannten Rohre sind zur Vermeidung des Eindringens von Schmelze flachgepreßt, wodurch sich das Rohr verspannt und innerhalb des Verschleißfutters abreißen bzw. platzen kann. Weiters ist der zugeführte Gasstrom breit gefächert. 2.1 The arranged in the wear lining of the metallurgical vessel as Known pipes serving flushing device are to avoid the Penetration of melt pressed flat, causing the tube tense and tear off or burst within the wear lining can. Furthermore, the gas flow supplied is wide-ranging.
  • 2.2 Um solche Verspannungen zu vermeiden und einen scharf gebündelten Gasstrahl zu erzielen, ist zentral in jedem Rohr (18) mindestens ein sich in Längsrichtung des Rohres (18) erstreckender stangenförmiger Einsatz (26) vorgesehen, der mit der Rohrinnenwand (29) einen Ringspalt (30) bildet. 2.2 To avoid such tension and a sharply focused Achieving a gas jet is central to at least one in each tube (18) Rod-shaped insert extending in the longitudinal direction of the tube (18) (26) is provided which with the inner tube wall (29) forms an annular gap (30) forms.
  • 2.3 Das Spülelement eignet sich für alle metallurgischen Gefäße, insbesondere für Stahlwerkskonverter. 2.3 The flushing element is suitable for all metallurgical vessels, especially for steel mill converters.
