钢铁长流程工艺体系中碳排放量占比非常大，炼铁发展绿色低碳技术对降低碳排放量尤为重要。针对铁水采用敞口铁水罐运输导致铁水热量损失大的问题，分析了敞口铁水罐运输铁水热量损失构成和对应的碳排放量实际情况，对铁水罐采取烘烤补热和加盖保温的节能减排效果进行对比分析，结果均可以提高铁水温度30 ℃以上。两种方式的应用实证和实现碳减排的结果表明，对铁水罐空罐期实施加盖保温效果最好，更有利于减排，且几乎不需要提供外部能源就可以大幅度减少铁水热量损失和降低碳排放量；烘烤补热是对加盖保温的补充和辅助，可实现传统高炉炼铁工艺的高炉煤气自循环，对于碳减排具有重要意义。

In the long-process steelmaking system, the proportion of carbon emissions is extremely high. Therefore, the development of green and low-carbon technologies in ironmaking is crucial for emission reduction. In allusion to the significant heat loss during the transportation of hot metal ladle without cover insulation, the composition of such heat loss and the corresponding actual carbon emissions were analyzed. A comparative analysis was carried out on the energy-saving and emission-reduction effects of hot metal ladle for heat compensation and ladle covering for heat preservation. The results showed that both methods could increase the molten iron temperature by more than 30 ℃. Empirical applications of these two methods and the achieved carbon emission reduction results indicated that applying cover insulation during hot metal ladle empty period was the most effective measure, which was more conducive to emission reduction. Moreover, it significantly reduced heat loss and carbon emissions with almost no external energy supply. Compensatory heating served as a supplement and auxiliary measure to cover insulation, could realize the self-circulation of blast furnace gas within the traditional blast furnace ironmaking process, which was of great significance for carbon emission reduction.
