Problems solved by technology

[0004] The quality requirements for converter equipment maintenance are high, the construction period is tight, and the construction personnel on site are heavily invested. At the same time, there are many hazards on the construction site, and there are a lot of cross operations on the construction site, and all node projects need to use the same crane. The next construction project can only be started after the direction of the converter mouth is changed in place after each construction task is completed. Therefore, online maintenance of large converters is a very systematic and meticulously organized project

Abstract

The invention provides a maintenance method for a converter. The maintenance method is applied to maintenance items of a converter body and a smoke hood system during maintenance of the converter, and the direction of a converter mouth is adjusted cooperatively so that all assemblies can be dismounted in a certain sequence; under the condition that the quality and safety are guaranteed, the construction period can be greatly shortened, labor cost and lifting and transferring cost for large hoisting equipment are greatly reduced, the effects of shortening the stop time, relieving labor intensity, reducing the workload, increasing field maintenance safety coefficient and the like are obvious, and the technique is advanced; and the maintenance method for the converter has obvious economic benefits and social benefits.

Description

technical field [0001] The invention relates to metallurgical equipment maintenance; [0002] In particular, it relates to a converter maintenance method. Background technique [0003] On-line maintenance of large-scale converters requires the replacement of damaged equipment on the main body of the converter and the replacement and maintenance of some converter flue gas recovery system equipment during the regular maintenance of the converter. With the evolution of the steelmaking process, some equipment will undergo corresponding transformation, and the maintenance process will also undergo corresponding changes. [0004] The quality requirements for converter equipment maintenance are high, the construction period is tight, and the construction personnel on site are heavily invested. At the same time, there are many hazards on the construction site, and there are a lot of cross operations on the construction site, and all node projects need to use the same crane. The ne...
