摘要中间包中生成微小气泡可显著促进夹杂物上浮去除。对中间包微气泡精炼技术进行了分析总结,并针对研究较为深入的长水口吹氩技术相关文献进行了详细分析。结果表明,利用中间包中钢液湍动能破碎气泡可形成高效去除夹杂物技术,一些新技术正在研发过程中,长水口吹氩技术具有良好前景;“冷钢片沾钢”工业试验表明,中间包长水口吹氩可在中间包钢液中生成弥散细小氩气泡,生成的绝大部分氩气泡尺寸小于2 mm;长水口吹氩生成微小气泡的过程可分为气泡在长水口壁孔脱附和脱附气泡在湍急钢流中被剪碎成微小气泡两个阶段,其中钢液湍动能对氩气泡的剪切破碎作用十分明显;长水口吹氩技术水模型研究较多,数值模拟研究相对较少,工业试验研究才刚刚开始,有待更进一步的深入研究。

Abstract：Fine bubbles produced in tundish have excellent abilities to help inclusion float and remove. The tundish fine bubble refining technologies were summarized and the literature related to the argon injection into ladle shroud technology was analyzed in detail. The results show that utilizing the molten steel with large turbulent energy in tundish to split bubbles into smaller ones can form a kind of high efficiency inclusion removal technology. Some new technologies are being developed, and the argon injection into ladle shroud technology has a good prospect. The industrial trial of "cold steel sheet sampling method " shows that fine dispersed argon bubbles can be formed in molten steel by the argon injection into ladle shroud technology, most of which are less than 2 mm in diameter. There are two stages during the formation process of fine bubbles in ladle shroud, bubble detachment in wall orifice and detached bubble being split into smaller ones in turbulent steel. The latter has an obvious effect on the shear fracture of argon bubble.There exist many reports on water model of the argon injection into ladle shroud technology, but few on numerical simulation, and the industrial experimental research is just beginning. We need to do more in-depth works.

Key words： tundish fine bubble inclusion argon injection into ladle shroud cold steel sheet sampling
