Abstract
The utility model provides a through-flow and spiral-flow type tuyere middle sleeve which is made of the combination of copper and steel and used for loading high-temperature hot-air into the inside of a blast furnace. The flange, the internal sleeve and the external sleeve of the through-flow and spiral-flow type tuyere middle sleeve are respectively processed and manufactured by evenly using pure copper plates, and an inducer-device is formed by welding steel materials. The inducer-device, the flange and the inner sleeve are welded to integration and then welded with the external sleeve to form the entirety of the through-flow and spiral-flow type tuyere middle sleeve. The through-flow and spiral-flow typetuyere middle sleeve is uneasy to deform under the high-temperature operating condition for the steel inducer-device is adopted to replace the public known cast process, the service life is long, the cooling effectiveness is better, and the manufacturing cost is reduced.
Description
Affiliated technical field
The utility model relates in the tubular and whirlwind-type air port of a kind of copper and steel combination and overlapping, and belongs to iron-smelting blast furnace supply air system equipment.
Technical background
At present, overlap in the known tubular and whirlwind-type air port, adopt full copper product to make, flange, interior cover and guiding device cast solid weld with overcoat again.Because the size deviation of foundry goods is bigger, the sectional dimension of water stream channel can not accurately be guaranteed, make the water coolant flow velocity in each hydroecium can't reach design requirements, therefore influence the reasonable distribution of water speed in middle cover, make cooling performance not ideal enough, cause to be enclosed within the air port local superheating to occur under the hot environment and deform even burn.And adopt the parts surface roughness height of casting technique, the drag losses that is produced when also causing flow of cooling water in the passage is bigger, and the hydraulic pressure of water coolant also must corresponding raising for this reason, thereby increases energy consumption.Because the cost height of copper material, more can't produce in quality height, the life-span is long and cost the is low air port and overlap.
Summary of the invention
Have the defective of overlapping in tubular and the whirlwind-type air port on manufacturing process and the material cost now in order to overcome, overlap in the tubular and whirlwind-type air port that the utility model provides a kind of copper and steel to make up, overlap in this air port that not only cooling performance is better, and reduced manufacturing cost, prolonged work-ing life.
The technical scheme that its technical problem that solves the utility model adopts is: the flange that overlaps in the air port, interior cover and overcoat still adopt the pure copper material, and its guiding device adopts the steel assembly welding to form.And all copper parts flanges, interior cover and overcoat all are processed into the fine copper plate, the cast copper that has replaced known technology, and flange, interior cover are the difference processing and fabricatings, after it reaches technical requirements fully to tolerance and surfaceness with process assembly welding all-in-one-piece steel guiding device and weld with argon arc welding technique, be welded into tubular with the fine copper overcoat again and the whirlwind-type air port in cover whole.
The beneficial effects of the utility model are, each parts is made accurately, guarantee that water coolant circulation area reaches design requirements, and water speed distributes rationally, good cooling results, and resistance is decreased and is reduced, and energy consumption is little.Invar material intensity, is avoided using under worst hot case occurring being out of shape, damaging so the bulk strength that overlaps in the air port is improved greater than copper material.Because price of steel product is lower than copper material, thereby has reduced manufacturing cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a longitudinal diagram of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the B-B sectional view of Fig. 2.
Embodiment
Structure such as Fig. 1, Fig. 2 and shown in Figure 3 of overlapping in the tubular and whirlwind-type air port of the utility model copper and steel combination, by flange 1, interior cover 2, overcoat 3, guiding device 4, water-in 5, water inlet pipe 6, the first high speed chamber 7, the second high speed chamber 8, the 3rd high speed chamber 9, distinguish 10 at a slow speed, water outlet 11, hole 12 form.
In Fig. 1, the guiding device of making of steel 4 is behind processing and assembly welding, and the water inlet pipe 6 with steel welds earlier, welds together with interior cover of being processed into the fine copper plate 2 and flange 1 then, puts the overcoat 3 that the fine copper plate makes again and welds.
In Fig. 1, Fig. 2 and embodiment shown in Figure 3, water coolant is entered in the air port by water-in 5 and overlaps, by water inlet pipe 6 water coolant is delivered to middle cover front end and need most the refrigerative first high speed chamber 7, then the hole 12 from guiding device 4 dividing plates enter successively the second high speed chamber 8, the 3rd high speed chamber 9, by cover front end after high-speed rotational is passed through successively backward, arrive and distinguish 10 at a slow speed, discharge in the air port through water outlet 11 again and overlap.
