PURPOSE: A nozzle combining structure of an oxygen lance for refining is provided to improve workability and reduce time for replacement of the nozzle by facilitating attachment and detachment of the nozzle. CONSTITUTION: A nozzle combining structure of an oxygen lance for refining comprises a first and a second housing, a first and a second stopper(30,40), a sealing member(50), and an O-ring(70), and an elastic unit. Tapered parts(11,12) are formed on one end of the first and the second housing. The first and the second housing are positioned on the end of each of the oxygen lance and the nozzle. The first and the second stopper are respectively positioned on the tapered part of the inside of the first and the second housing. The sealing member is a tubular member positioned to connect to the oxygen lance and the nozzle. The O-ring is positioned on the grooves(51a,51b) of the sealing member. The elastic unit is positioned between the both ends of the sealing member. |
