以铁-钢界面理论研究为依据，分析了铁水“一罐到底”的技术特征和优势，包括铁水温降、保温、计量等方面。并结合昆钢实际情况进行了简要的分析，找出这个方案存在的问题和应对措施，认为铁-钢界面铁水采用“一罐到底”工艺方案在昆钢新区可行。

Based on the BF-BOF technology interface theory, one ladle system from BF to BOF technique feature and advantage was analyzed, including hot metal temperature drop, heat preservation, measurement, etc. At the same time, benefit was analyzed in practice for Kunming Iron and Steel Co., Ltd. problems of it were found and approached, it was concluded that the mode of using one open ladle is feasible at new zone of KISC.
