The converter post-blow argon stirring process may further promote carbon-oxygen reaction in liquid

effectively decreases converter end oxygen content in liquid. The results of commercial test of 120 t combined blown converter post-blow argon stirring process show that the post-blow argon stirring process may decreases the converter end carbon-oxygen product

with bottom blowing rate 800 m

before argon stirring； the (FeO) decreases to 13. 7% from 18. 5% ； the average ［S］ decreases to 0. 005% from 0. 009% and the average ［P］ decreases to 0. 006% from 0. 008%; after stirring for 3 ~6 min

the average temperature of liquid decreases 10 - 20 °C.
