Abstract
The utility model discloses an automatic steel ladle drainage device which is applied in a steel-making system, and aims to greatly reduce the use quantity of drainage sand, simplify the operation procedure and simultaneously reach the purpose of automatic steel ladle drainage. The technical point is that the utility model comprises a cylinder, the drainage sand and a fusible object, wherein one end of the cylinder is closed, the drainage sand is arranged in the cylinder, the fusible object is used for sealing the other end of the cylinder, the cylinder body is made of a material which can be melted in molten steel, and is a whole body formed by a cylinder, and the side of the cylinder body is formed with one or more side holes. When the automatic steel ladle drainage device is used, an automatic diverter is inserted in a steel ladle nozzle, when the steel ladle is vertical, the drainage sand in the cylinder can automatically fill the space among an upper steel ladle nozzle and brick cups, and the purpose of automatic steel ladle free-opening can be realized. The automatic steel ladle drainage device is suitable for the steel ladles under all steel-making process conditions, and has the advantages that the operation is simple, the power dust pollution can be reduced, the cost can be saved, the process time can be shortened, and the automatic drainage rate is stable.
Description
Technical field
The utility model relates to a kind of ladle draining device that is applied in the steelmaking system.
Background technology
At present, steel mill both domestic and external generally adopts from the ladle the method for throwing in drainage sand in the ladle nozzle brick cup to reach the function of ladle automatic jet.The shortcoming of this kind method is that the waste of drainage sand is serious, and use amount is excessive, and produces a large amount of dust pollutions, and activity time is long, severe operational environment.
The ladle draining device that prior art discloses is by loam cake, body, drainage material and the cylindrical barred body of going to the bottom and forming; Loam cake and body are made by meltable thin slice shape sheet material, and loam cake and pipe diameter are suitable; Drainage material (drainage sand) is loaded in the body, goes to the bottom to be meltable film, and wrapping is in the body bottom.Insert from ladle nozzle during use.Though it can prevent that slag from stopping up ladle canal, can not reach the purpose of automatic jet.Because between drainage rod and the mouth of a river, the pocket block certain slit or space must be arranged, molten steel flows into the slit and can cause the thickening of drainage sand sinter layer to deepen, and when beginning to pour into a mould, ferrostatic pressure is pressed and do not broken sinter layer, causes the ladle can not automatic jet.And in the today that steel quality is required improve day by day, the ladle automatic jet is the most basic requirement to drainage sand or drainage system, because if ladle can not automatic jet, just need to burn oxygen, can aggravate the secondary oxidation of molten steel, cause field trash to increase, thereby influenced steel quality, and increased the potential safety hazard of burning the oxygen operating personnel greatly, also can upset normal rhythm of production; The consuming cost of burning the oxygen pipe on the other hand is excellent high more a lot of than drainage.
Summary of the invention
The purpose of this utility model is both to have reduced drainage sand consumption significantly, alleviates dust pollution, simplifies procedures, and shortens activity time.Can reach simultaneously the purpose of ladle automatic jet again.
The technical solution of the utility model is: a kind of steel ladle automatic flow diverter, comprise the cylinder of end sealing, the drainage sand in the cylindrical shell, and the lyotrope of the closed circular cylindrical shell other end, its middle cylinder body is made by the material that can be melted in molten steel; It is characterized in that cylindrical shell is the integral body that is made of a cylinder, the cylindrical shell side has one or more side openings.
Aforesaid steel ladle automatic flow diverter, the lyotrope of the closed circular cylindrical shell other end is meltable film.
Aforesaid steel ladle automatic flow diverter, the side opening of cylindrical shell side seals with lyotrope.
Aforesaid steel ladle automatic flow diverter, the lyotrope of closed cylinder side side opening is meltable film.
Aforesaid steel ladle automatic flow diverter, described side opening can be arbitrary shapes, and wherein the area of single maximum side opening is greater than 3mm
2
Aforesaid steel ladle automatic flow diverter, its far-end of described side opening apart from the distance of cylinder end opening end greater than 200mm.
Aforesaid steel ladle automatic flow diverter, described cylindrical shell can be the polygon cylindrical shells.
Compared with prior art, the beneficial effects of the utility model are:
1. the function that had both had the ladle automatic jet is compared with the method for throwing in drainage sand again, has saved drainage sand consumption more than 60 percent;
2. reduced significantly because of burning the secondary oxidation of steel that oxygen causes, reduced and burnt dust, the smoke pollution that oxygen produces;
3. operating personnel have been reduced because of burning the potential safety hazard that oxygen causes;
4. really shorten activity time, alleviated labor intensity of operating personnel, improved working environment;
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the present utility model: 1. iron plate sealing end; 2. drainage sand; 3. steel cylinder; 4. side opening; 5. steel cylinder opening.
The specific embodiment
Below in conjunction with accompanying drawing a preferred embodiment of the present utility model is further described.
In the accompanying drawing, flow diverter of the present utility model is by iron plate sealing end 1, drainage sand 2, and steel cylinder 3 is with the side opening 4 of plastic membrane sealing with steel cylinder opening 5 formations of plastic membrane sealing; Side opening 4 in the present embodiment is a rectangle, and its width is 30mm, and length is 300mm.
During use, steel cylinder sealing end 1 forward, side opening 4 upwards inserts in the ladle along the ladle nozzle level, closes the mouth of a river; Be used for the thin slice of closed cylinder side opening 4 or film melted by heating this moment, along with holding up of ladle, the drainage sand in the flow diverter flows out along side opening 4, and slit, the space between brick cup, the mouth of a river and the device entered in filling; When ladle begins to pour into a mould, open slide gate nozzle, the meltable film that is used to seal steel cylinder opening 5 this moment is melted by heat, and the drainage sand in the tube flows out from steel cylinder opening 5, and the outer drainage sand of tube is again along side opening 4 counter flowing in the steel cylinder, and flows out from steel cylinder opening 5; This moment and the drainage sand at molten steel contact interface place is sintering, forms sinter layer, and because drainage sand has flowed out along steel cylinder end opening 5 and caused below the sinter layer emptyly, sinter layer begins distortion under the effect of ferrostatic pressure; After opened fully at the mouth of a river, the support that sinter layer has lost steel cylinder continued distortion, and when the sinter layer distortion acquired a certain degree, sinter layer broke, and molten steel flows out, and forms automatic jet.
In the present embodiment, this steel cylinder is that the common iron of Q235 is made by steel grade.
The steel cylinder side has the side opening of one or more Any shape, and purpose is to allow drainage sand can flow out or flow into once more steel cylinder smoothly; The material of sealing steel cylinder opening can also replace with thin slice or the general thin of other serviceability temperatures at 40 ℃～1200 ℃.
