The lance system is one of the important link of converter. Stable and secure of the system is a necessary condition for whole production system to function normally. The numerical simulation for a three-dimensional oxygen lance nozzle was carried out according to the fundamental parameters of PZH steel, the characteristics of the oxygen jet were analyzed and discussed. The oxygen lance nozzle with the optimum design has achieved good results in practice: the average formation time of early slag was reduced by 1 min and 23 seconds, the pure blowing time was reduced by 46 seconds, the oxygen consumption per ton steel decreased by 1.05 m3/t, the rate of dephosphorization was increased by 1.35%, the basicity of slag was reduced by 0.38, the phosphorus and sulfur distribution ratio between slag and liquid iron were also increased effectively.

In this paper, hydraulic model experiment is performed for comparing the agitation ability of the coherent blowing and the top-bottom blowing. And numerical simulation is implemented for studying the influence of the concomitant flow temperature and pressure on the core space of the main jet. And the results show that the agitation ability of the coherent blowing and the top-bottom blowing is considerable. And the core space of the main jet of lance increases along with the increasing of the concomitant flow temperature under a certain pressure.
