在二炼钢顶吹转炉建设过程中,有人建议改为底吹转炉。为明确其现实可能性,很难单凭国外介绍的文献资料,还有必要了解国内在这方面过去已进行了的试验和当前的情况。这对当前二炼钢的建设和将来一炼钢的技术改造都有意义。公司于1975年夏组织了炼钢厂、钢研所、设计院、技术处向兄弟厂作了一次学习调查。在调查中同时了解了侧吹转炉,由于目前侧吹转炉在国内比重较大,了解的情况还比底吹较多。调查的单位有马钢、上钢、鞍钢、唐钢、天钢及首钢等,调查的重点是目前国内氧气侧吹及底吹转炉的试验生产情况、冶炼特点和效果、设备情况、操作经验及存在的主要问题。现将调查结果综述于下。
In the second steel-top converter construction process, it was suggested to change to the bottom converter. In order to clarify its realistic possibility, it is very difficult to rely solely on the literature and materials imported from abroad. It is also necessary to understand the experiments and the current situation that have been carried out in the country in the past. This is of great significance for the construction of the current two steelmaking plants and the technological transformation of a steelmaking plant in the future. The company organized a steel mill in the summer of 1975, Steel Institute, Design Institute, Technical Office made a learning survey to the brothers plant. In the survey at the same time understand the side-blown converter, because the current side-blown converter in the country a larger proportion of understand more than the end of blowing more. The investigation units include Masteel, Shanghai Iron and Steel, Anshan Iron and Steel, Tangshan Iron and Steel, Tiangang and Shougang, the survey focuses on the current domestic production of oxygen side blowing and bottom blowing converter trial, smelting characteristics and effects, equipment, operating experience and There are major problems. The survey results are summarized below.
