Embodiment Construction

[0028] A method for offline assembly and moving of a large-volume blast furnace body, comprising the following steps:

[0029] 1. First make five reinforced concrete cast-in-place beams on the open space corresponding to the straight line of the original old blast furnace body as the foundation of the moving platform.

[0030] 2. Install a number of moving steel beams on the basis of the moving platform, and use steel supports to tie them firmly. The moving steel beams are made of steel plates, and steel rails are laid on them, and multiple sets of power mobile vehicles are set on the steel rails;

[0031] 3. On the open space corresponding to the straight line of the original old blast furnace body, a new blast furnace body is rebuilt on the power mobile car on the rail. The bottom plate of the furnace shell is directly placed on the power mobile car, and the furnace body is lined Together with the completion of the new furnace body masonry;

[0032] 4. Install the external ...

Abstract

The invention relates to an off-line assembly and push-conveying method of a large-capacity blast furnace body. The off-line assembly and push-conveying method comprises the following steps: a, makinga push-conveying platform foundation on an open ground linearly corresponding to an original old blast furnace body; b, mounting a plurality of push-conveying steel beams on the push-conveying platform foundation, paving steel rails on the push-conveying steel beams, and arranging a power moving trolley on the steel rails; c, on the open ground linearly corresponding to the original old blast furnace body, making a new blast furnace body on the top surface of the power moving trolley; d, mounting a hydraulic push-conveying device and a hydraulic jacking device on the back side of the new furnace body; e, mounting a hydraulic lifting device on the top steel beam of a framework of the blast furnace body; f, pushing the new blast furnace body to a design position; g, utilizing the hydrauliclifting device to lower the upper structure of the new furnace body and enable the upper structure to be abut joint with a lower structure and carrying out butt welding; and h, and carrying out concrete pouring on the new blast furnace body. The method is suitable for the repair of the large-capacity blast furnace body and the change of the furnace body structure. Production can be prevented frombeing affected, so that the repair period of the blast furnace body is short, and the production halt time is short.

Description

technical field [0001] The invention belongs to the replacement technology of the blast furnace structure of the industrial system, in particular to an off-line assembly and moving method of a large-volume blast furnace body. Background technique [0002] With the development of modern industry, equipment is developing toward large-scale, high-efficiency, and low-energy consumption. The volume of the blast furnace is also increasing, but the furnace body of the blast furnace operates continuously at high temperature, and its furnace body structure and equipment are easily damaged and have a short service life. The traditional method is generally to partially replace the damaged furnace body structure and equipment every year, and for the blast furnace shell structure, water wall, and furnace roof charging equipment that are seriously damaged after several years of operation, it is necessary to replace it as a whole. However, the traditional replacement method takes a long t...
