The behaviour of a free gas jet is used to study the dynamic variations of lance distance to supply oxygen in impinging jet steelmaking practice. It is shown that the dimensionless momentum flow rate within the jet describes satisfactorily the plant data on variation of lance distance to supply oxygen. Correlations are proposed to determine the lance distance to supply oxygen and its variation during the blow.
