摘　　要：中间包在钢水连铸过程中起到承上启下的作用,承担着分流、稳压、调质和控温等功能。作为钢水接触的最后一个耐火材料容器,中间包因其较大的容积和稳定的流动条件,被视为非金属夹杂物上浮去除的理想场所。随着对铸坯质量和钢水洁净度要求的不断提高,中间包的冶金功能越来越受到研究人员的重视,开发出多种先进中间包冶金技术,研究人员采用水模试验、数值模拟、在线原位检测等方法,对新技术条件下中间包内的多相传输现象进行了深入研究。基于近年中间包冶金的研究现状,综述了包括中间包感应加热、微气泡冶金及夹杂物多孔陶瓷过滤在内的中间包冶金新技术,探讨了中间包冶金未来的发展方向。The tundish plays the role of connecting the upper and lower levels in the continuous casting process of molten steel,and undertakes the role of diversion,pressure stabilization,component adjustment and temperature control.As the last refractory container in contact with molten steel,the tundish is regarded as an ideal place for the floating removal of non-metallic inclusions due to its large volume and stable flow conditions.With the increasing re-quirements of the quality of continuous casting billet and the cleanliness of molten steel,the function of tundish met-allurgy has attracted more attention from researchers.Many advanced tundish metallurgical technologies have been developed.Researchers have investigated the multi-phase transport phenomena in the tundish with novel approa-ches,through water modeling,numerical simulation,on-line measurement,and so on.Based on the research status of tundish metallurgy in recent years,the new technologies of tundish metallurgy,including induction heating of tundish,micro-bubble metallurgy and porous ceramic filtration of inclusions are reviewed.The further progress of tundish metallurgy is also discussed.
