摘　　要：为缩短转炉冶炼周期,通过改进氧枪喷头参数实现提高供氧流量而氧压不升高,达到缩短供氧时间、提高一倒出钢率的目的。因设计喷头喉口直径增加,氧射流冲击深度略深,实际操作过程中枪位适当提高加以应对。In order to shorten the smelting cycle of converter,the oxygen flow rate is increased without the increase of oxygen pressure by improving the parameters of oxygen lance nozzle,so as to shorten the oxygen supply time and increase the first pouring rate.Due to the increase of nozzle throat diameter,the impact depth of oxygen jet is slightly deeper,so the gun position should be appropriately increased in the actual operation process.

关 键 词：冶炼周期 供氧流量 喉口直径 冲击深度
