A doubleparameter oxygen lance used in a 300 t converter was designed to improve the metallurgical performance. A smallscale measurement of the jet behavior was done using a computer controlled scanning system. The experimental data on the velocity distribution at the jet centerline, the contour map of the jet velocity, the deviation of the jet centerline, and the velocity distribution of the axial section were compiled. According to the results of the smallscale measurement, the doubleparameter lance was also employed for a BOF experiment. The metallurgy indexes show that the metallurgical performance was highly promoted by use of the doubleparameter lance.
