[0131] Such as figure 1 , 2 As shown, a blast furnace 1 is located at a construction site, and its furnace body 3 is built on a furnace foundation 4 . A furnace body tower 5 for supporting the furnace body 3 is arranged around the blast furnace 1 . When the furnace body 3 is disassembled, it is disassembled into the furnace bottom member 6 and the ring building member 7 above and carried out. When moving out the furnace bottom member 6 and the ring-laying member 7, the ring-laying member 7 can be hoisted by a jack (not shown) arranged on the furnace body tower 5 . Then, the unloaded furnace bottom member 6 and ring building member 7 are transported to a work site 8 far away from the furnace body 1, and both are disassembled separately.

[0132] A furnace shell 6A is provided on the outside of the furnace bottom member 6 , and refractory bricks 6B are provided on the inner periphery and bottom surface of the furnace bottom member 6 . After the blast furnace 1 is shut down, ...

Abstract

Provided are a ring block conveying apparatus using no dolly, and a remedy method for a blast furnace casing. This remedy method comprises a preparing step of installing both a conveying route (20) leading from an installation site (2) to a working site and a conveying frame (30) made slidable on the conveying route (20) and having a placing face (31) on the upper side, a separating step of cutting the portion of a foundation (4) of a furnace casing (3) horizontally at the height of the placing face (31) and cutting an upper portion (7) of the furnace casing (3) horizontally thereby to cut outa furnace bottom block (6), a transferring step of moving the furnace bottom block (6) horizontally to transfer the same onto the placing face (31), and a conveying step of moving the conveying frame(30) placing the furnace bottom block (6) thereon, along the conveying route (20) to the working site.

Description

technical field [0001] The present invention relates to a conveying device for a ring-shaped component and a method for overhauling a blast furnace body, in particular, to a device and method for moving in or out a ring-shaped component when a blast furnace is being refurbished or dismantled, and the device and method are particularly Suitable for efficient loading and unloading of heavy furnace floor components. Background technique [0002] When a blast furnace is newly built or overhauled, the blast furnace body is built, and when the blast furnace is overhauled or abandoned, the blast furnace body is dismantled. [0003] At present, there is a so-called large ring construction method of the furnace body (furnace body ring big block method), which refers to dividing the furnace body into a plurality of ring-shaped components in the axial direction when building or dismantling the blast furnace body (Refer to Patent Document 1). [0004] When this construction method is ...
