Paper Title:
Research on High-Efficiency Oxygen Blowing Technology for Semi-Steel Steelmaking
  Abstract

To improve the production efficiency of converter smelting and keep stabled during refining in Panzhihua Steel, the original nozzle was optimized and industrial tests have been carried out. Results show that the optimized nozzle has a better metallurgical effect on the condition that corrosion of lining is normal, the average volume of oxygen and oxygen supply intensity were increased by 1040 m3/h and 0.27 m3/(t •min) respectively, oxygen consumption was reduced by 1.99m3/t, the blowing time was lowered by 1.06 minutes, TFe content in slag is 19.65%, which is 1.5 percentage point lower than that of the original one. So, a better dephosphorization effect was obtained and metal loss is controlled.
