高炉- 转炉区段铁水运输温降综述

节能降耗是钢铁企业长期发展的核心内容，高温铁水作为冶炼过程中能量流的载体，铁水温度始终是降低钢铁生产成本、保障钢铁产品质量的关键因素之一。综述了高炉- 转炉区段铁水热量损失的主要方式和影响因素，分析了铁水运输过程温降的关键问题，指出了新型界面技术——“一包到底”模式，是铁水运行周期短、温降小的基本保障。钢铁企业还可以通过研制铁水覆盖剂，减小铁水面散热；优化铁水包保温结构，包括增设绝热层和保温盖等措施，有望为进一步减小铁水温降提供参考和依据。

Review on temperature drop of hot metal from BF to BOF

Energy saving is the core content of long- term development in steel plant. Hot metal with high temperature is regarded as the carrier of energy flow during the smelting process, and the temperature of hot metal is always one of the key factors to reduce the cost of steel production and ensure the quality of steel products. By reviewing the main methods and influencing factors of hot metal heat loss from blast furnace to basic oxygen furnace, the key problems of temperature drop in the transportation of hot metal were analyzed. It was pointed out that the new interface technology "one ladle mode" was the basic guarantee for the period and the small temperature drop. Hot metal covering could be prepared for reducing the heat loss of hot metal surface. And the heat insulation structure of hot metal ladle should be optimized, including the addition of insulation layer and lid, which could provide reference and basis for further reducing the temperature drop of molten iron.
