摘　　要：介绍了首钢京唐钢铁联合有限责任公司在高炉-转炉界面通过采用大型铁水包运输车、精确称量、铁水包动态跟踪、铁水包保温等关键技术,成功实现了铁水包多功能化,简化了高炉-转炉界面,缩短了流程,稳定了铁水装入量,降低了铁水温降,提高了KR铁水脱硫处理的温度,为KR高效脱硫提供了良好的热力学条件,KR脱硫终点铁水w(S)稳定地控制在25×10-6以下,为建立"全三脱"高效低成本洁净钢生产平台创造了有利条件。The paper introduces key technologies of BF-BOF interface about hot metal la- dle＇s transportation, accurate weighing, dynamic tracking and heat preservation in Shougang Jingtang. The multi-functional hot metal ladle technology has been succeeded achieved. The BF-BOF interface was simplified, the process route was shorten, the charge weight of hot metal was stable, and the hot metal temperature drop has been decreased. Then the hot metal temperature for desulphurization has been increased, and the thermodynamics conditions for KR desulphurization were created. The mass fraction of sulfur in hot metal at the end of KR treatment can be controlled steadily below 25 × 10-6. The favourable conditions for the construction of three D （decarbonization, desulfurization and dephosphorization ） efficient low-cost clean steel production platform have been achieved.
