Description

Technical Field

[0001] This invention belongs to the technical field of converter steelmaking equipment installation, and in particular relates to a method for synchronously installing the converter charging span structure and equipment. Background Technology

[0002] Metallurgical converter steelmaking projects, as complex large-scale metallurgical engineering projects, are characterized by complex three-dimensional structures, high structural installation difficulty, equipment installation within confined spaces, and long construction periods. The converter charging span is located between the converter furnace span and the converter electrical room. Installation work can only proceed along the column line to one side. Structurally, the roof beams and part of the trolley beams of the charging span are installed on the high-rise frame columns of the furnace span. An elevated furnace front platform is located directly in front of the furnace span to connect the furnace span and the converter electrical room. This platform, as the main working platform for converter equipment installation, is crucial, especially the cable corridor installed below it, which is used to lay cables connecting the converter equipment and the electrical cabinets, directly affecting the installation and commissioning of the equipment. Figure 1 As shown, the current installation of the charging span structure and equipment involves constructing the charging span steel structure sequentially from line 1 to line 7 in a front-to-back direction. Only after the charging span steel structure is completed is the furnace platform and equipment installed. This results in a late start time for equipment installation and severe limitations due to construction space constraints, which is the main reason for the long installation cycle in converter projects. Therefore, optimizing the converter process and developing a method for simultaneous installation of the converter charging span structure and equipment to solve the problem of long installation cycles in converter projects is of great significance for promoting project construction and improving construction efficiency. Summary of the Invention
