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.
