Description

technical field [0001] The invention relates to a method for installing a steelmaking converter, in particular to a method for installing a large-scale furnace steel converter. Background technique [0002] The traditional installation method of large-scale steel-making converters is to use a ladle trolley and a special platform in accordance with YJGF-94 "Installation Method for Large-scale Converter Body", and use a hydraulic jacking device for installation. Since the ladle trolley is the production equipment of the steel mill, it is generally unwilling to rent it as an installation tool. At the same time, the furnace shell of the converter is supplied in sections, and sometimes the welding seam on the construction site is set at the position of the support ring, so the above method cannot be used. There have been precedents of installing converters by sliding method in foreign countries. However, they fully considered the design during the construction of the plant, cha...
