| Zusammenfassung: | The invention discloses a coaxial dual supersonic speed oxygen flow beam concentration oxygen lance. The coaxial dual supersonic speed oxygen flow beam concentration oxygen lance comprises an inner layer round hole supersonic speed spraying pipe assembly, an outer layer water cooling casing pipe assembly and a middle layer ring hole supersonic speed spraying pipe assembly between the inner layer round hole supersonic speed spraying pipe assembly and the outer layer water cooling casing pipe assembly; the round hole supersonic speed assembly generates a first beam of supersonic speed oxygen jetflow; the ring hole supersonic speed assembly generates a second beam of supersonic speed oxygen jet flow surrounding the first beam of supersonic speed oxygen jet flow, and the second supersonic speed oxygen jet flow and the first supersonic speed oxygen jet flow are same in direction, and can achieve independent gas supply and independent adjusting. The coaxial dual supersonic speed oxygen flows can be formed, under th |
