| Zusammenfassung: | The utility model relates to an oxygen lance joint, in particular to an oxygen lance joint for a blasting taphole of a blast furnace, which belongs to blast furnace scrap iron treatment equipment. The oxygen lance joint comprises steel tubes; the inner diameter of the first steel tube is the same as the outer diameter of the second steel tube; the first steel tube and the second steel tube are connected in an inserted mode and welded into a whole; a bolt is arranged at the upper end of the first steel tube; an O-shaped sealing ring is mounted at the connection position of the first steel tube and the second steel tube; and the radial section of the inserted end of the second steel tube is conical. The oxygen lance joint for the blasting taphole can be used for rapidly replacing an oxygen lance, thereby decreasing or eradicating escape of oxygen from the joint and improving operation progress. |
