为提高钢的洁净度,减少钢中夹杂物含量,采用超声波工具头直接插入高温钢液进行处理的方法,对比研究了超声波处理和吹氩处理去除钢液中夹杂物的效果.结果表明:超声波单独处理可以减少钢液中Al2O3夹杂物,但去除率较低,约为4%～12%;随着超声处理时间的增加和超声波功率的减小,夹杂物去除率提高.吹氩单独处理时,钢液中夹杂物去除率较高,为29%～41%;随氩气流量的增加,夹杂物去除率呈升高的趋势. In order to improve the cleanliness of steel and reduce the content of inclusions in steel, the ultrasonic tool head was directly inserted into the high-temperature molten steel for treatment, and the effects of ultrasonic treatment and argon blowing treatment on the inclusions in molten steel were compared.The results show that ultrasonic The separate treatment can reduce the Al2O3 inclusions in the molten steel, but the removal rate is low, about 4% ~ 12%; with the increase of ultrasonic treatment time and ultrasonic power, inclusions removal rate increased. , And the removal rate of inclusions in molten steel is higher from 29% to 41%. With the increase of argon flow rate, the removal rate of inclusions tends to increase.
