In order to meet the need of production and promote the smelting efficiency of converter, Pangang Vanadium-extracting&Steel Making Plant optimized oxygen lance nozzle according to the situation of primary 120t converter semi-steel making and have inspected new oxygen lance's smelting effect in industrial test. The test shows that the average oxygen blowing intensity raised 0.19m(3)/t.min with optimized nozzle, shortened oxygen blowing time by 56s, total iron in final slag reduced 0.7%, dephosphorizing rate rose to 82.10% from 79.06%, which developed a good result.
