| titleOfInvention | A kind of single channel double structure oxygen lance nozzle |
| abstract | The utility model relates to a kind of single channel double structure oxygen lance nozzles, including oxygen intake, Laval pipe main aperture, Laval pipe secondary orifices, Laval pipe main aperture and Laval pipe secondary orifices interlaced arrangement, it is characterised in that, Laval pipe main aperture is Narrow Flare Angle large aperture, and Laval pipe secondary orifices is large angle small-bore.In converting process, main aperture jet intensity is improved, and enhances spray head jet stream to the impact effect and stirring intensity in molten bath, the jet core area lengthening distance of main aperture spray head.Secondary orifices jet stream then effectively alleviates the jet stream decaying of main aperture, and molten bath impact area obviously increases, slugging significant effect；The fusion distance of each stock jet stream rises appreciably in furnace, converges possibility and substantially reduces, and in the case where major-minor hole cooperates, splash rate is substantially reduced, and because intercolumniation gap increases, is conducive to increase cooling water flow, spray head cooling effect is obvious, extends spray head service life. |
