The invention discloses a blast furnace shell middle section replacement method, and relates to the technical field of blast furnace shell replacement construction. The height and angle of a furnace shell are adjusted through an external electric chain block, the furnace shell is transported to an installation position, and the furnace shell is pulled to the installation position through an internal electric chain block to be welded. The replacement method is suitable for replacing the furnace shell at the uniform section and the variable section of a blast furnace, and is wide in applicationrange. A first electric chain block and a second electric chain block are used for controlling the conveying position of a new furnace shell, a third electric chain block is combined for positioning the furnace shell, furnace shell replacement operation is accurate, operation is easy, safety is high, a furnace shell conveying platform does not need to be built or other parts of a furnace body do not need to be disassembled, the construction efficiency is remarkably improved compared with the prior art, the construction progress is accelerated, and the construction cost is saved.

    本发明公开了一种高炉炉壳中间段的更换方法,涉及高炉炉壳更换施工技术领域。本发明利用外部电动倒链调整炉壳高度和角度,将炉壳运输至安装位置,并通过内部电动倒链将炉壳拉到安装位置进行焊接。本发明提出的更换方法适用于高炉等截面和变截面处炉壳的更换作业,适用范围广;利用第一电动倒链和第二电动倒链控制新炉壳的运输位置,并结合第三电动倒链定位炉壳,使炉壳更换作业精准,操作简单,安全性高,不用搭建炉壳运输平台或拆卸炉体其他部件,较传统施工方法的施工效率有显著提高,加快施工进度,节约施工成本。
