1982年3月在KHIC厂炼钢车间安装了一台ASEA-SKF钢包精炼炉。该炉的任务是对电弧炉钢水进行精炼和真空脱气,以提供高纯洁度钢水,用于生产锻造钢锭和优质铸钢件。实践证明该炉能完全满足用户对钢质量的非常严格的要求,并已采用精炼钢水真空碳脱氧法生产发电机、汽轮机转子和叶轮等的优质钢锭。本文阐述了用电弧炉和这台钢包炉联合生产430t 2.8NiCrMoV钢锭的操作经验,并介绍了KHIC厂炼钢车间的概况和ASEA-SKF钢包炉的操作经验。
In March 1982, an ASEA-SKF ladle refining furnace was installed in the KHIC plant’s steelmaking plant. The furnace is tasked with the refining and vacuum degassing of EAF molten steel to provide high purity steel for the production of forged ingots and high quality castings. Practice has proved that the furnace can fully meet the users of the steel quality of the very strict requirements and has adopted the vacuum molten steel carbon deoxidation method to produce generators, turbine rotors and impellers, and other high-quality steel ingot. This paper describes the combined operation of EAF and this ladle furnace to produce 430t 2.8NiCrMoV steel ingots and presents an overview of the KHIC steelmaking plant and the operating experience of ASEA-SKF ladle furnaces.
