Abstract
The utility model provides a tubular and swirl tuyere small sleeve which is made of the cobination 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 tuyere small 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 tubular and swirl tuyere small sleeve. The tubular and swirl tuyere small 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 to the tubular and whirlwind-type tuyere small sleeve of a kind of copper and steel combination, belongs to iron-smelting blast furnace supply air system equipment.
Technical background
At present, known tubular and whirlwind-type tuyere small sleeve adopts full copper product to make, and 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 little cover, make cooling performance not ideal enough, cause tuyere small sleeve under hot environment, local superheating to occur 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 quality height, the life-span is long and cost is low tuyere small sleeve.
Summary of the invention
In order to overcome the defective that has now on tubular and whirlwind-type tuyere small sleeve manufacturing process and the material cost, the utility model provides the tubular and whirlwind-type tuyere small sleeve of a kind of copper and steel combination, this tuyere small sleeve 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: except the flange of tuyere small sleeve, interior cover and overcoat still adopt the pure copper material, 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 whirlwind-type tuyere small sleeve integral body.In addition according to customer requirements, can also be at the heat resistant and wear resistant alloy of 2～3 millimeters of the interior cover of tuyere small sleeve and overcoat front end built-up welding one decks, to resist washing away and grinding of coal dust and coke.
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 of tuyere small sleeve 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.
Embodiment
The structure of the tubular and whirlwind-type tuyere small sleeve of the utility model copper and steel combination as shown in Figure 1 and Figure 2, by flange 1, interior cover 2, overcoat 3, guiding device 4, heat resistant and wear resistant alloy welding deposit floor 5, water-in 6, water inlet pipe 7, the first high speed chamber 8, the second high speed chamber 9, the 3rd high speed chamber 10, the 4th high speed chamber 11, distinguish 12 at a slow speed, water outlet 13 forms.
In Fig. 1, the guiding device of making of steel 4 is behind processing and assembly welding, and the water inlet pipe 7 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.The heat resistant and wear resistant alloy 5 that last tuyere small sleeve front end built-up welding one deck of finishing in assembling again is 2～3 millimeters.
In Fig. 1, embodiment shown in Figure 2, water coolant is entered by water-in 6, by water inlet pipe 7 water coolant is delivered to little cover front end and need most the refrigerative first high speed chamber 8, after high-speed rotational is passed through successively backward by front end along the second high speed chamber 9, the 3rd high speed chamber 10, the 4th high speed chamber 11 of overcoat 3 inwalls and 4 formation of guiding device then, arrive and distinguish 12 at a slow speed, discharge tuyere small sleeve through water outlet 13 again.
