Embodiment Construction

[0032] In order to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0033] A construction method for vertically laying and inlaying bricks on a cooling wall of a blast furnace, comprising the following steps:

[0034] Step 1: After leaving the factory, the stave water-cooled pipes are transported to the construction site after the pressure test. The construction site is within the working radius of the large-scale crane for blast furnace shell installation (the construction site is flat and firm, and it can achieve the vertical placement of the stave 16 without collapsing) ;

[0035] Step 2: Turn the stave 16 over on site and place it upright (with the lifting lug 18 facing upwards), and use the anti-tilt support frame to support and fix the stave 16 (the stave 16 is placed in a centralized manner according to the principle of placing th...

Abstract

The invention relates to the technical field of brick-embedded staves in blast furnace construction, in particular to a construction method for vertically laying bricks inlaid with staves of a blast furnace. Step 1: Pressure test the water-cooled pipes of the stave and transport them to the construction site; Step 2: Turn the stave over on site and place it upright, and use the anti-tilt support frame to support and fix the stave; Step 3: Pop out the stave according to the actual width of the stave Lay the bottom row of inlaid bricks on the longitudinal center line of the stave; Step 4: Lay each remaining row of inlaid bricks in turn from bottom to top until all masonry is completed; Step 5: Hoist the stave after the masonry is completed. The construction process of this method is: pressure test of stave water-cooled pipe-transportation to site-site turning-over-masonry-hoisting. Compared with the traditional brick-embedded construction method, this method has simplified procedures, short construction preparation time, and low construction site requirements. , The scheme uses less material and less construction equipment, which improves the work efficiency and work quality.

Description

technical field [0001] The invention relates to the technical field of brick-embedded staves in blast furnace construction, in particular to a construction method for vertically laying bricks inlaid with staves of a blast furnace. Background technique [0002] Blast furnace stave inlaid with bricks, the traditional method is to set up a shelf dedicated to the stave inlaid with bricks in a relatively large and flat site. The staves transported to the construction site are first subjected to pressure test. After passing the pressure test, the staves are turned over (during the pressure test, the water-cooled pipes are facing upwards), transported, hoisted, and finally placed on the shelf. After the bricks are finished, the cooling stave must be hoisted from the construction frame, then transported to the blast furnace and placed upright, and finally hoisted and installed. [0003] The mud used in the brick-laying of the stave is prepared by water and refractory powder. The br...
