Other AbstractSome characteristics relating jet performance of multi-jet oxygen lance are studied. The relationship between two parameters Kj and #lambda#j which describe the velocity distribution for the axisymmetric supersonic jet is derived. A mathematical model of velocity distribution for multi-jet is established and Computer-aided-experiment can be performed. Some results are obtained on the jet impact area and the characteristics of velocity distribution on axis of multi-nozzle. Finally the results of the present dissertation are used in the derelopment of oxygne lance of 300-ton converter for Baoshan Steel Complex and the expected results for the nozzle design have been achieved.
