Detailed description of the invention
A kind of blast furnace blowing device combined installation method provided by the present invention, comprises the concrete steps that:
(1) belly pipe is installed: weld two hangers in the appropriate location of furnace shell and two calabashs 12 are set, and use bustle pipe manual trolley hoist 11 that belly pipe 6 is installed, and ensure that belly pipe 6 holds out against tuyere small sleeve 7, ensure the levelness of belly pipe 6 flange, use support angle steel 13 to fix temporarily.
(2) expansion joint simulator is used to determine the Xiang Guan center of gooseneck and bustle pipe: such as Fig. 4,5 making expansion joint simulators, roll an external diameter and build the steel pipe support 1 of the little 1-2mm of endoporus than refractory material in belly pipe 6, upper and lower side at steel pipe support 1 is respectively welded center determiner 2 and level adjuster 4, and cuts a rectangular opening being easy to operation center's determiner 2 in the upper end of steel pipe support 1; Wherein center determiner 2 is the bolt 3 of welding top, the center sharpening at diameter circular steel plate more slightly larger than steel pipe support 1 diameter, and center determiner 2 ensures their concentricity with steel pipe support 1 when welding; Level adjuster 4, it it is one adjusting bolt 5 of each welding on the corner of size rectangular steel plates more slightly larger than the diameter of steel pipe support 1, level adjuster 4 is penetrated by steel pipe support 1 and is welded and fixed, and should ensure that the angle between them is identical with the angle of belly pipe 6 flange Yu the angle of expansion joint 9 centrage before welding.
As steel pipe support 1 lower end of simulator is inserted in belly pipe 6 by Fig. 3, slightly adjust gap uniformity between itself and belly pipe 6, the adjustment bolt 5 adjusting level adjuster 4 reaches level, the bolt 3 of center determiner 2 is regulated again through the rectangular opening of cutting on steel pipe support 1, make the top of bolt 3 leave the marking on bustle pipe 8, so just have found such as center when Fig. 4 gooseneck 10 passes through with bustle pipe 6 phase. Remove expansion joint simulator, using plans draw gooseneck and bustle pipe pass through profile mutually, and carry out perforate.
(3) lifting gooseneck: respectively weld a hanger in the both sides up and down of bustle pipe perforate, calabash is used to insert in bustle pipe by gooseneck, and weld two blocks and fix temporarily, the insertion depth of gooseneck is bigger than the design size of drawing, it is simple to strengthen the space that expansion joint is installed.
(4) expansion joint is installed: utilize the hanger arranged installing belly pipe 6 and gooseneck 10, three calabashs is set expansion joint 9 is installed, use fixing bolt that the flange of expansion joint 9 with belly pipe 6 is carried out centering and fix.
(5) adjust and centering gooseneck: the block on gooseneck is removed, adjust gooseneck, use bolt that itself and expansion joint flange are carried out centering and fixes.
(6) welding gooseneck: according to installation drawing technology requirement, the weld seam between welding gooseneck and bustle pipe continuously.
(7) blowpipe draw bar is installed, removes and support angle steel: install such as Fig. 1 between belly pipe 6 and furnace shell, blowpipe draw bar 14 between expansion joint 9 and furnace shell, remove the support angle steel 13 in Fig. 2, complete whole installation.
The 1580m of certain steel mill3Blast furnace adopts this installation method in installing, and has shared 10 days and has been mounted with 16 set air-supply arrangements, has substantially increased efficiency of construction, and be effectively ensured construction quality.
