摘　　要：以120 t双孔底吹氩钢包为研究对象,设计一种间歇式底吹氩气模式,与传统的双孔底吹氩模式进行对比。结果表明:在精炼过程中,间歇式吹氩模式2(弱吹流量60 NL/min,吹氩时间10 s;强吹流量800 NL/min,吹氩时间20 s)提供的搅拌能是传统吹氩模式的1.84倍,还为钢-渣界面反应提供了反应时间,不但使得钢液在脱S、脱O方面取得良好效果,而且精炼出的成品金相组织致密,无夹杂物、空洞等缺陷。间歇式吹氩模式还降低了氩气消耗,在一定程度上实现了节能降耗。Taking 120 t double-hole argon bottom blowing ladle as the research object,an intermittent argon bot-tom blowing model is designed and compared with the traditional double-hole argon bottom blowing model.The results show that in the refining process,the intermitent argon blowing mode 2(weak blowing flow rate 60 NL/min,blowing time 10 s;strong blowing flow rate 800 NL/min,blowing time 20 s)provides sufficient stirring energy during the refi-ning process,and also provides reaction time for the steel-slag interface reaction,which not only achieves good results in the removal of S and O from the steel liquid,but also produces a dense alloy structure without defects such as inclu-sions and voids.The intermittent argon blowing mode also reduces the consumption of argon gas,which realizes energy conservation and consumption reduction to a certain extent.
