Abstract
The utility model relates to an air seal submersed nozzle. The upper end of a nozzle body is in a hollow inverse cone shape and is provided with a steel casing seal cover; an annular air flow chamber is formed between the steel casing seal cover and the nozzle body and is provided with an air outlet at the upper port of the nozzle body; and the outer wall of the steel casing seal cover is provided with an inert gas inlet. According to the air seal submersed nozzle, the steel casing seal cover is added, a rib structure at the upper port of the nozzle body is combined, and an inert gas outlet is moved to the upper end of the nozzle body, so that residue entrained by molten steel cannot be splashed into the inert gas outlet; and the space for assembling a sealing ring between an upper nozzle and a lower nozzle is increased, and size of the sealing ring is increased, so that a sealing effect of the upper nozzle and the lower nozzle can be improved.
Description
Technical field
The utility model belongs to the smelting iron and steel technical field, specifically relates to a kind of sealing gland submersed nozzle.
Background technology
In the prior art, the structure of sealing gland submersed nozzle is as shown in Figure 1, and body 1 upper end in the mouth of a river offers inert gas air inlet 2; Corresponding inert gas air inlet 2 offers cannelure 4 on mouth of a river body 1 upper end inwall; When filling pipe end 5 connection mouth of a river bodies 1, inert gas gets into cannelures 4 through air inlet 2, utilizes the filling pipe end 5 and the fit clearance of mouth of a river body 1 to overflow and forms the protection air-flow; Isolated outside air enters into the mouth of a river, prevents that the molten steel of fusion is oxidized.The mouth of a river weak point of version has like this: 1, the residue carried secretly of molten steel is splashed into cannelure 4 easily, even stops up cannelure 4, causes the poorly sealed close of annular inert gas, and outside air gets into the mouth of a river with molten steel oxidation; 2, owing to offered cannelure 4; It is less to leave the space that sealing ring 3 is installed between filling pipe end 5 and the mouth of a river body 1 so for; The sealing ring 3 short and small sealing effectiveness that also reduce easily cause when annular inert gas poorly sealed close, and outside air gets into the mouth of a river with molten steel oxidation.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of sealing gland submersed nozzle is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of sealing gland submersed nozzle; Comprise mouth of a river body; Body upper end, the mouth of a river is hollow reverse frustoconic, and the upper end of said mouth of a river body is provided with the iron-clad seal closure, looping air-flow chamber between iron-clad seal closure and the mouth of a river body; The port place of annular airflow chamber body at the mouth of a river is provided with the gas outlet, and iron-clad seal closure outer wall is provided with the inert gas air inlet.
As preferably, the port of said mouth of a river body is provided with some radially fins, the gas outlet at the groove looping air-flow chamber body port place at the mouth of a river between adjacent lugs.
As preferably; The iron-clad seal closure of body upper end, the said mouth of a river comprises end cap and case, and end cap seal is connected on the case, and the inert gas air inlet is arranged on the outer wall of case; Case lower port inwardly turnover has the sealing ring, and sealing ring hoop is on the body outer wall of the mouth of a river.
The utility model has installed the iron-clad seal closure additional, in conjunction with the fin structure of mouth of a river body port, makes to move on to body upper end, the mouth of a river on the gas outlet of inert gas, and the one, the residue that molten steel is carried secretly can not be splashed into the gas outlet of inert gas; The 2nd, increased the space that sealing ring is installed between the mouth of a river up and down, sealing ring is amplified the sealing effectiveness that can improve between the two.
Description of drawings
Fig. 1 is a kind of structural representation at the mouth of a river in the prior art;
Fig. 2 is a kind of structural representation of the utility model;
Fig. 3 is a kind of split structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: referring to Fig. 2~Fig. 3; Body 1 upper end, the utility model mouth of a river is hollow reverse frustoconic; The upper end of mouth of a river body 1 is provided with iron-clad seal closure 6; Looping air-flow chamber between iron-clad seal closure 6 and the mouth of a river body 1, the port of mouth of a river body 1 are provided with some radially fins 11, the gas outlet at the groove 12 looping air-flow chamber body 1 port place at the mouth of a river between adjacent lugs.Iron-clad seal closure 6 comprises end cap 61 and case 62, and end cap 61 is sealedly connected on the case 62, and inert gas air inlet 2 is arranged on the outer wall of case 62, and case 62 lower port inwardly turnover have sealing ring 63, and sealing ring 63 hoops are on mouth of a river body 1 outer wall.
During installation; Case 62 is inserted in from the bottom up; Make sealing ring 63 hoops on mouth of a river body 1 outer wall, end cap 61 sealings are welded or are screwed onto on the case 62, combine the fin structure of mouth of a river body port like this at mouth of a river body 1 port place; Make to move on to body upper end, the mouth of a river on the gas outlet of inert gas, the one, the residue that molten steel is carried secretly can not be splashed into the gas outlet of inert gas; The 2nd, increased the space that sealing ring 3 is installed between filling pipe end 5 and the mouth of a river body 1, sealing ring 3 is amplified the sealing effectiveness that can improve between the two.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection domain that belongs to the utility model.
