Abstract
The utility model discloses a casting and forging combined tuyere medium sleeve. The tuyere medium sleeve comprises an outer sleeve provided with a front cavity along the circumference direction thereof, and a main body with one end surface in welding connection with the outer sleeve; a through-hole is formed in the center of the main body, and a cavity is formed in the main body; a water inlet and a water outlet which are communicated with the cavity are formed on the other end surface of the main body; a water inlet pipe with two ends communicated with the water inlet and the front cavity in the outer sleeve respectively is inserted into the cavity; and a plurality of guide rings are alternately and symmetrically welded on two sides of the water inlet pipe in such a manner that one end of each guide ring is welded on the water inlet pipe, and gaps exist between the other ends of the guide rings and the pipe wall of the water inlet pipe. By adopting the device, the material requirement for the thinnest part at the front end of the tuyere medium sleeve is met; the service life of the tuyere medium sleeve is prolonged; the manufacture process is simplified; and the manufacturing cost is reduced. Additionally, cooling water is enabled to rotationally flow backwardly with decreasing flow speeds from the top down sequentially, so that the cooling water speed and the temperature distribution of the tuyere medium sleeve are consistent, and the cooling effect of the tuyere medium sleeve is improved.
Description
Technical field
The utility model relates in the air port in a kind of ironmaking tuyere of blast furnace device in blast furnace cooling apparatus field and overlapping, and particularly relates to a kind of the employing in casting and the air port of forging the technology making that combines and overlaps.
Background technology
Cover is one of parts of blast-furnace tuyere device in the air port, is installed between tuyere big sleeve and the tuyere small sleeve, and the cover front end inserts furnace wall inside in the air port, works to support tuyere small sleeve.Cover adopts the fine copper casting in traditional air port, and its complete processing is generally the sand mo(u)ld moulding, and the fine copper casting forms.Because cast copper material thermal conductivity is lower, when the blast furnace furnace wall was subjected to Effect of Hyperthermic Environment generation partial fracture, the cover front end was exposed under the interior hot environment of blast furnace in the air port, produces distortion even scaling loss because of local superheating easily.Utility model patent 200420004397.3 discloses a kind of " overlapping in the tubular and whirlwind-type air port of copper and steel combination " in the prior art, and its body and overcoat all adopt the calendering copper coin to make.Though this air port can make the air port thermal conductivity improve, reduced the problem of overlapping in the air port because of local superheating distortion scaling loss, improved the air port life-span, the manufacture craft more complicated, production cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of material needs that both satisfied cover weak part in the air port are provided, and has simplified manufacture craft again, and a kind of casting that has reduced manufacturing cost is forged in the combined type air port and overlapped.
A kind of casting of the present utility model is forged in the combined type air port and is overlapped, it comprises the overcoat that along the circumferential direction is provided with ante-chamber, the body that an one end face and described overcoat are weldingly connected, described body centre has through hole and its inside is provided with cavity, described body other end has water-in and the water outlet that is connected with described cavity, in described cavity, be inserted with its two ends respectively with described water-in, the water inlet pipe that the ante-chamber that puts outward is connected, a plurality of guide ring one ends alternately are welded on the both sides of described water inlet pipe and its other end and described water inlet pipe tube wall symmetrically and leave predetermined spacing.
The utility model device is because the mode that adopts cast forging process to combine, making body is single part but not assembly, has so both guaranteed the needs of cover front end weak part material in the air port, has improved in the air port and has overlapped work-ing life, simplify manufacture craft again, reduced manufacturing cost; And the guide ring in this device need not perforate, thereby also simplified manufacture craft, reduced manufacturing cost; Again because the cooling structure that singly goes out whirlwind-type is singly advanced in employing, directly water coolant is delivered in the air port cover front end and needed most the refrigerative position, and make the water coolant speed eddy flow that slows down successively backward from high to low, make the temperature distribution of overlapping in water coolant speed and the air port consistent, improved and overlapped cooling performance in the air port.

Fig. 1 is a kind of A-A view of forging the device shown in Figure 2 that overlaps in the combined type air port of casting of the present utility model;
Fig. 2 is the end view drawing of device shown in Figure 1;
Fig. 3 be device shown in Figure 2 along B-B to water stream channel horizontal spreading figure.
Embodiment
Below in conjunction with accompanying drawing and specific examples the present invention is done to describe in detail.
In Fig. 1, the utility model device comprises the overcoat 3 that along the circumferential direction is provided with ante-chamber, the body 1 that an one end face and described overcoat 3 are weldingly connected, described body 1 centre has through hole and its inside is provided with cavity, described body 1 other end has water-in 4 and the water outlet 6 that is connected with described cavity, in described cavity, be inserted with its two ends respectively with described water-in 4, the water inlet pipe 5 that ante-chamber on the overcoat 3 is connected, a plurality of guide ring 7 one ends alternately are welded on the both sides of described water inlet pipe and its other end and described water inlet pipe tube wall symmetrically and leave predetermined spacing.Described spacing can be provided with according to the required cooling intensity of each hydroecium.Be welded with stiffening web 2 between the described adjacent guide ring.Interval between the described adjacent guide ring 7 is strengthened by predetermined proportion according to the direction from overcoat to water-in, the principle setting that described predetermined proportion can strengthen gradually according to the required cooling intensity of each hydroecium and circulation area.Described body 1 is formed by the fine copper casting, and overcoat 3 is formed by fine copper plate rolling processing.
During aggregate erection, guiding device (a plurality of refluence rings 7 that weld together by stiffening web 2) welds together with steel water inlet pipe 5 earlier, and then with body 1 welding assembly together, on body 1, put overcoat 3 at last and weld.In the present embodiment, the trend of water coolant as shown in Figure 3.Water coolant at first directly enters air port overcoat ante-chamber by water-in 4 and water inlet pipe 5, this moment, water speed was for the highest, water speed design meets the required cooling intensity requirement of operating mode, and water coolant flows out by water outlet 6 at last along the trend of the guide ring cover end eddy flow in the air port that slows down gradually then.
