Description
Technical field
It the utility model is related to a kind of Con casting ladle long nozzle alignment device of continuous casting of iron and steel technical field.
Background technology
With the continuous improvement that user requires steel product quality, the content of nonmetallic inclusionsin steel how is reduced, and then
The cleanliness factor of steel is improved, has become the emphasis of steel-making scientific and technical research.Molten steel is contacted with the oxygen in air, causes secondary oxygen
Change is the important sources of steel inclusion.Continuous casting is last procedure in STEELMAKING PRODUCTION, caused by during this
Secondary oxidation, which is mingled with to be difficult to float, to be removed, and tends to vary with molten steel solidification in strand, its harm is the most serious.
To avoid secondary oxidation of steel, casting process reduces contact of the molten steel with air using various means.Con casting ladle
Long nozzle is a kind of device of continuous casting protective casting, installed in water gap bowl at the top of ladle bottom, ladle long nozzle and water under ladle
Mouth connection, outlet at bottom are immersed in the molten steel in tundish molten bath, for conveying molten steel from ladle to continuous casting production.
Since ladle long nozzle is located at tundish molten bath area top and ladle lower part, temperature scorch down, worker can not be close,
Therefore, the installation of ladle long nozzle is to use people's manipulator's arm, and the mechanical arm front fork equipped with long nozzle is rotated to peace
Position is filled, the water gap bowl of ladle long nozzle is directed at collector nozzle of ladle, operating robotic arm is lifted up, by water under long nozzle and ladle
Mouth connection, and hold out against, prevent the junction air-breathing of the water gap bowl of collector nozzle of ladle and long nozzle.
The problem of presently, there are：1st, when ladle long nozzle is installed, water gap bowl and the collector nozzle of ladle on long nozzle top export
Alignment function difficulty is big, and typically operative employee operates, it tends to be difficult to be aligned, and cause long nozzle to connect by rule of thumb by visually observing
It is poorly sealed to meet place, causes the secondary oxidation of molten steel；2nd, the multiple alignment function of ladle long nozzle easily causes the mouth of a river of long nozzle
The breakage of bowl refractory material, causes long nozzle poorly sealed, or even damaged.
The field trash that problem above causes secondary oxidation of steel to be formed often has little time floating and is put into crystallizer, gently then makes
Be mingled with into strand it is exceeded, seriously affect continuous casting normally production and product quality.
Utility model content
The purpose of the utility model is to overcome prior art defect, there is provided a kind of Con casting ladle long nozzle alignment device,
To solve long nozzle and collector nozzle of ladle outlet alignment difficulties, the flimsy problem of installation process.
What the technical solution of the utility model was realized in：A kind of Con casting ladle long nozzle alignment device, by overall steel
The umbrella-rib shape of system forms header, backing ring and vertical connecting, and umbrella-rib shape links together header by least three heads
Steel wire forms, and vertical connecting upper end is connected with steel wire head, and vertical connecting lower end is connected with backing ring center, and steel wire is with vertical
Oliquely downward symmetrical centered on connecting rod, backing ring is the taper inversed taper platform shape consistent with long water gap bowl taper, can be close to put
In long water gap bowl.
Preferably, umbrella-rib shape is made of header four steel wires all around, and every steel wire dips down horizontal by 60 °
Tiltedly.
Preferably, the distance of every steel wire end and vertical connecting is equal to or slightly less than collector nozzle of ladle radius.
Preferably, backing ring outer ring is welded by iron sheet, and backing ring internal welding is connected to spoke, spoke center and vertical connecting
Lower end is connected.
Preferably, backing ring bottom is connected with vertical annular circle bottom.
When ladle long nozzle is installed, the utility model is placed in water gap bowl, header is guided upwards by umbrella-rib shape,
It can ensure that ladle long nozzle is disposably accurately directed at collector nozzle of ladle, mouth of a river installation effectiveness improves, and air-tightness is good after installation, keeps away
Damaged in collision of the collector nozzle of ladle to long water gap bowl is exempted from, and when molten steel passes through long nozzle, the utility model is i.e. by molten steel
Fusing, will not be manufactured into steel quality any influence.

Embodiment
It is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Con casting ladle long nozzle alignment device, by the umbrella-rib shape of integrated steel to mark
Head, backing ring 3 and vertical connecting 2 form, 1 group of the steel wire that umbrella-rib shape is welded together header by four heads all around
Into 2 upper end of vertical connecting is connected with 1 head of steel wire, and 2 lower end of vertical connecting is connected with 3 center of backing ring, and steel wire 1 is with vertical
Centered on connecting rod 2, symmetrical, every 1 end of steel wire and the distance of vertical connecting 2 are tilted down horizontal by 60 °
Equal to or slightly less than 5 radius of collector nozzle of ladle, backing ring 3 is the taper inversed taper platform shape consistent with 4 taper of long water gap bowl, can be close to put
In long water gap bowl 4,3 outer ring of backing ring is welded by iron sheet, and 3 internal welding of backing ring is connected to spoke 7, and 7 center of spoke connects with vertical
2 lower end of extension bar is connected.
During operation, the utility model is placed on 4 bottom of long water gap bowl, 3 bottom annular circle bottom 6 of backing ring enters long nozzle
Tube body, ensure that umbrella-rib shape is attached to 4 bottom margin of long water gap bowl to header vertical center, 3 side wall of backing ring, ensure that this practicality is new
Type does not slide out of long nozzle tube body；Then mechanical arm is used, long nozzle is moved to the lower part of collector nozzle of ladle 5, is slowly carried
Long nozzle is risen, ensures that umbrella-rib shape enters collector nozzle of ladle 5 to the top of header first, long nozzle is gradually jacked, according to umbrella-rib shape
Four steel wires 1 of header all around are touched with the situation at 5 edge of collector nozzle of ladle, adjusts mobile long nozzle；Lasting top
Long nozzle is risen, the position of long nozzle is constantly adjusted, until four umbrella-rib shapes do not touch 1 end of header steel wire or just touch ladle
In the case of 5 inner wall of collector nozzle, umbrella-rib shape is all sent into collector nozzle of ladle 5 to header, and is held out against, installation process is completed.
