Embodiment Construction

[0021] In order to further describe the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0022] A method for hoisting and replacing staves for maintenance and maintenance of a blast furnace, characterized in that: it is carried out in accordance with the following steps:

[0023] 1. Make cooling wall special trays in the blast furnace

[0024] Such as figure 2 As shown in the figure, the workers transport materials such as I-beams, channel steels, and platform plates back into the blast furnace through the iron mouth frame, and make a cooling stave installation special tray 2 suitable for the inner diameter of the blast furnace shell 1 .

[0025] 2. Unimpeded cooling stave hoisting special channel

[0026] Such as image 3 , Figure 4 As shown, from the bottom of the blast furnace top inspection hoist to the platform of each layer of the furnace top platform, a special channel 9 for s...

Abstract

The invention discloses a hoisting method for replacing a cooling wall in overhauling of a blast furnace. The hoisting method is characterized by comprising the following steps of: 1, making a special pallet for installing the cooling wall in the blast furnace; 2, unchoking a special channel for hoisting the cooling wall; 3, installing a windlass and fixed pulleys on a platform at the top of the furnace; and 4, hoisting the cooling wall by a furnace top overhauling hoist. The hoisting method disclosed by the invention has the advantages of reasonable installation, safety and reliability, the time of replacing the cooling wall is saved, and the overhauling cost is reduced.

Description

technical field [0001] The invention relates to the technical field of blast furnace equipment hoisting, in particular to a hoisting method for blast furnace maintenance cooling stave replacement, which is suitable for blast furnace maintenance cooling stave replacement. Background technique [0002] At present, in metallurgical steelmaking blast furnaces, it is often encountered that the staves are burned through or severely corroded by molten iron, and the staves need to be replaced. How to make the cooling stave from the ground to the furnace after the pressure test is completed has become a technical problem. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a hoisting method for replacing cooling staves for blast furnace maintenance, so as to make the replacement of cooling staves for blast furnace repairing fast, safe and accurate. [0004] The object of the present invention...
