Optimization and Application of Oxygen Lance Nozzle for 120t Converter of Pangang
In order to meet the requirement of semi-steel making, the original nozzle was optimized by Vanadium-recovery ing and Steel-making Works of Pangang. And then every parameters of the oxygen lance were assessed according to industrial tests. Results show that, comparing with the original oxygen lance nozzle the new designed one has a better metallurgical effect, the average volume of oxygen and oxygen supply intensity were increased by 774m7h and 0.19 m3/(t-min) respectively, oxygen consumption was reduced by 1.87m3/t, the blowing time was lowered by 56 seconds, a better dephosphorization effect was obtained by the new one.
