gas flow rate and injection location on mixing time for a 300 t hot metal desulphurization-pretreated by double-lance injection process at Baosteel has been studied by 1 :3.5 water modelling. Results showed that the effect of stirring by off-centre injection was better than that by centre injection ; the deeper the insertion lance
the shorter the mixing time
but the impact to refractory in bottom increased; with increasing gas flow rate the return flow zone increased and the mixing time decreased ; and the mixing time for injection by bending lance decreased by 10% ~30% as compared with that by straight lance.
