摘 要:本文是利用水模拟钢液体，空气模拟氧气，由转炉顶部垂直插入的氧枪将空气吹入以水模拟的钢液熔池中。研究液面高度,枪位变化，气流量等因素的变化来测试氧枪对液面喷溅量和混匀时间的影响，通过实验研究，结果表明在当模型顶吹气体流量≥28m³/h时，枪位和流量变化对熔池均混时间影响较小;熔池的喷溅量随枪位降低和顶吹气体流量的增加而增加;当气体流量为32m³/h时，熔池的喷溅量较大。

ABSTRACT:This paper was to use water simulation steel liquid oxygen from air simulation of converter, the top vertical insert oxygen lance will air blowing water simulation of liquid steel in the pool. Research liquid surface height, gun a change, factors such as gas flow changes to the test of liquid surface oxygen lance spillage effect of quantities and blending time, through experiment and research, the results showed that the when model of gas flow rate (28m ³ / h p, gun bits and flow changes of molten pool are less affected mixing time; Pool with gun a spillage of quantity of gas flow rate reduced and top-blown increases; When the gas flow ³ / h, 32m spillage of molten pool large quantities.
Keywords: basic oxygen; top gun flow; gun bits ;are mixing time ; impact depth
