Studies concerning the effect of stirring and post‐stirring on the oxygen distribution at the end of the LD process show that a post‐stirring phase following the end of the blow establishes an oxygen distribution close to equilibrium. The sub‐lance tests performed at 90% of the oxygen throughput show in comparison with the post‐stirring phase a distinct oxygen deficiency, while the blow end‐point measurements show an excess of oxygen.
