Abstract
The utility model discloses a long mouth of a river of air cooling wherein package ring, including the ring body, the inboard equipartition of ring body has the stainless steel baffle, is equipped with annular air -cooled chamber in the ring lateral wall, the gas vent is seted up in ring body inboard in the air -cooled chamber of annular, the ring body outside is equipped with the air inlet that link up with annular air -cooled chamber, and the air inlet is used for carrying nitrogen gas to the air -cooled intracavity of annular, through setting up annular air -cooled chamber in the ring lateral wall, cool off the ring body to the nitrogen gas that the air -cooled intracavity of annular fills into certain pressure through the air inlet, the gas vent is opened at the ring inboardly, can carry out secondary cooling to the long mouth of a river and stainless steel baffle during the exhaust, has reduced the temperature of ring body, has prevented that the ring is appeared by heat altered, has prolonged the life of ring, reduction in production cost and intensity of labour.
Description
Technical field
The utility model relates to technical field of metallurgical equipment, particularly relates to bag long nozzle backing ring in a kind of air-cooled type.
Background technology
In steel plant continuous casting is produced, large bag long nozzle is put in water opening support ring, by being connected of manipulator and the mouth of a river under large Baogang water pot, to realize in large Baogang water pot molten steel by large bag long nozzle inflow tundish.Because the heat transfer of the aluminium charcoal mouth of a river is fast, originally for putting the backing ring at the quartzy mouth of a river, will be heated in casting process and redden, after completing the molten steel circulation in a large bag, long nozzle backing ring will be out of shape, bring difficulty to the large bag long nozzle of installation, change backing ring frequently and bring much inconvenience to production and maintenance, not only increase labour intensity and production cost, also extend the production time, thus have impact on the benefit of enterprise.
Utility model content
Technical problem to be solved in the utility model is to provide bag long nozzle backing ring in a kind of air-cooled type, has good stability under the high temperature conditions, not yielding, can Long-Time Service, reduces labour intensity and production cost.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: bag long nozzle backing ring in a kind of air-cooled type, comprise backing ring body, stainless steel separator is evenly equipped with inside backing ring body, annular air-cooled chamber is provided with in backing ring sidewall, exhaust outlet is offered in the air-cooled chamber of described annular inside backing ring body, is provided with the air inlet that air-cooled chamber is through with annular outside described backing ring body, and air inlet is used for supplying nitrogen in the air-cooled chamber of annular.
Described stainless steel separator is vertically arranged and axis around backing ring body evenly lays four pieces.
Described exhaust outlet to be opened between adjacent stainless steel separator and around the axis of backing ring body uniform four.
Along the arcwall face being indent in described backing ring inner body wall, the neck outer wall profile of arcwall face and long nozzle is suitable.
The beneficial effect adopting technique scheme to produce is: by arranging annular air-cooled chamber in backing ring sidewall, the nitrogen being filled with certain pressure by air inlet in the air-cooled chamber of annular is cooled backing ring body, exhaust outlet is opened inside backing ring, cooling twice can be carried out to long nozzle and stainless steel separator during exhaust, reduce the temperature of backing ring body, prevent backing ring temperature distortion, extend the service life of backing ring; Have four pieces of stainless steel separators inside backing ring, in stainless steel separator, edge and long nozzle wall contacts, prevent long nozzle from directly contacting with backing ring inwall, can completely cut off certain heat, have also been enlarged cooling twice space; The upper inside wall of backing ring body is also designed to arcwall face, this arcwall face is consistent with long nozzle neck outline, the stress effectively can eliminating long nozzle neck is concentrated, long nozzle neck is avoided to rupture, significantly extend the service life of long nozzle, guarantee continuous casting of molten steel quality, reduce production cost and labour intensity.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As Figure 1-3, the utility model discloses bag long nozzle backing ring in a kind of air-cooled type, comprise backing ring body 2, stainless steel separator 1 is evenly equipped with inside backing ring body 2, annular air-cooled chamber 5 is provided with in backing ring sidewall, exhaust outlet 4 is offered in the air-cooled chamber 5 of described annular inside backing ring body 2, is provided with the air inlet 3 that air-cooled chamber 5 is through with annular outside described backing ring body 2, and air inlet 3 is for supplying nitrogen in the air-cooled chamber 5 of annular; Described stainless steel separator 1 is vertically arranged and axis around backing ring body 2 evenly lays four pieces; Described exhaust outlet 4 to be opened between adjacent stainless steel separator 1 and around the axis of backing ring body 2 uniform four; Along the arcwall face being indent on described backing ring body 2 inwall, the neck outer wall profile of arcwall face and long nozzle is suitable.
In embody rule process, long nozzle is arranged on backing ring of the present utility model, first the nitrogen of certain pressure (0.4 ~ 0.8MPa) is passed into from air inlet 3, the nitrogen in annular air-cooled chamber 5 is entered to after the cooling of backing ring overall structure from air inlet 3, discharge from exhaust outlet 4, backing ring inwall, stainless steel separator and long nozzle are cooled, and four pieces of stainless steel separators 1 that backing ring inwall is connected separate backing ring inwall and long nozzle, increase cooling space, significantly extend the service life of long nozzle.
In a word, the utility model by arranging annular air-cooled chamber in backing ring sidewall, the nitrogen being filled with certain pressure by air inlet in the air-cooled chamber of annular is cooled backing ring body, exhaust outlet is opened inside backing ring body, cooling twice can be carried out to long nozzle and stainless steel separator during exhaust, reduce the temperature of backing ring body, prevent the temperature distortion of backing ring body, extend the service life of backing ring; Have side to have four pieces of stainless steel separators in backing ring, in stainless steel separator, edge and long nozzle wall contacts, prevent long nozzle from directly contacting with backing ring inwall, can completely cut off certain heat, have also been enlarged cooling twice space; The upper inside wall of backing ring body is also designed to arcwall face, this arcwall face is consistent with long nozzle neck outline, the stress effectively can eliminating long nozzle neck is concentrated, long nozzle neck is avoided to rupture, significantly extend the service life of long nozzle, guarantee continuous casting of molten steel quality, reduce production cost and labour intensity.
