钢包内喷嘴与透气砖吹氩去夹杂水模型研究

通过选择乳状液滴模拟夹杂物和偏心底吹钢包水模型实验，考察了喷嘴和透气砖吹气条件下时间、吹气量对夹杂物去除行为的影响规律．结果表明：较小气量和较大气量分别在8和16min内可将绝大部分的模拟夹杂物去除，28min内可将模拟夹杂物几乎全部去除；喷嘴吹气时存在一个最佳去夹杂气量，而透气砖吹气时较小气量的去夹杂效果要好于较大气量，且在一定的气量范围内通过透气砖吹气的去夹杂效果要明显好于通过喷嘴吹气．

Water Model Study on Removing Inclusions in a Ladle With Argon Injected Through

The effects of time and gas flowrate on inclusion removal in a ladle with eccentric bottom gas injected through nozzle and porous plug were investigated by choosing emulsion drops simulated as inclusions in a water model. The results show that most of the inclusions can be removed in eight minutes with smaller flowrates, while sixteen minutes needed with larger flowrates. All the inclusions which have the possibility to be removed almost disappeared from the system in twentyeight minutes. With gas blowing through nozzle, there was a gas flowrate to be the best for inclusions removal. With gas injected through porous plug, smaller gas flowrates seemed to be more efficient for inclusions removal. And within a range of gas flowrates, gas injected through porous plug seemed to be more efficient for inclusions removal than gas blowing through nozzle.
