Description
Technical field
The utility model relates to packet argon gas emptier in a kind of continuous casting, belong to metallurgy industry STEELMAKING PRODUCTION equipment and technology neck
Domain.
Background technique
Middle packet argon gas emptier is that the air in middle packet is discharged by being passed through argon gas into middle packet, the middle packet now used
Argon gas emptier dispels area and more concentrates, be easy to cause pocket block temperature decline, cause open pour during the mouth of a river in
Portion generate attachment, cause stopper to go up, more seriously pocket block temperature is too low, open pour during molten steel diffusing be easy
Cause the production accidents such as wadding stream.
Utility model content
The utility model aim is to provide packet argon gas emptier in a kind of continuous casting, can improve gas of the argon gas in middle packet
Body flow field direction, make argon gas be uniformly dispersed in middle packet evacuation procedure can quickly and not reduce in wrap in the case where temperature
Air in middle packet is discharged, solves the problems, such as background technique.
The technical solution of the utility model is:
Packet argon gas emptier in a kind of continuous casting, includes support rod, tunger tube, exhaust pipe and gas vent, and the one of tunger tube
End is connect with argon gas gas source, and the other end of tunger tube is vertically connected on the centre of exhaust pipe, and the both ends of the exhaust pipe are closing
Structure, exhaust pipe are equipped with multiple rows of gas vent along central axial direction, and the angle between adjacent two rows gas vent is 30-35 degree,
Support rod is vertically fixed on tunger tube.
Gas vent of the exhaust pipe in central axial direction is three rows, nine gas vents of every row.
The both ends of the exhaust pipe are respectively provided with a gas vent.
The support rod and exhaust pipe are arranged vertically with tunger tube.
The utility model is used, in use, support rod is fixed on middle packet backpack cover by a bracket, exhaust pipe is put
Enter the gas vent entrance that 200mm in packet is deep, and argon gas passes through the rows of gas vent and both ends in exhaust pipe central axial direction
In middle packet, quickly air in middle packet can be discharged.
The beneficial effects of the utility model are: gas flowfield direction of the argon gas in middle packet can be improved, make argon gas in
Be uniformly dispersed in packet evacuation procedure, can quickly and not reduce in wrap in air in middle packet be discharged in the case where temperature, reduction
Impact to pocket block baking temperature enhances the Rapid replacement of air in centering packet.Molten steel secondary oxidation is prevented, steel is improved
Liquid degree of purity, reduction, which is opened, pours the rise of process stopper, improves slab quality.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the utility model left view；
Fig. 3 is the utility model top view.
In figure: support rod 1, tunger tube 2, exhaust pipe 3, gas vent 4.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, packet argon gas emptier in a kind of continuous casting includes support rod 1, tunger tube 2, exhaust pipe 3 and exhaust
The one end in hole, tunger tube 2 is connect with argon gas gas source, and the other end of tunger tube 2 is vertically connected on the centre of exhaust pipe 3, the row
The both ends of tracheae 3 be enclosed construction, exhaust pipe 3 along central axial direction be equipped with multiple rows of gas vent, it is adjacent two rows gas vents it
Between angle be 30-35 degree, support rod 1 is vertically fixed on tunger tube 2.
In the present embodiment, exhaust pipe 3 is the steel pipe of length 250mm, diameter 32mm.It is set along the length direction of steel pipe
Three row's gas vents are set, the angle of 9 gas vents of every row, adjacent two rows gas vent is 30-35 degree, and is respectively provided at steel pipe both ends
The gas vent of one Φ 25, tunger tube 2 are vertically welded in the centre of exhaust pipe 3,
Support rod 1 is the steel pipe of length 400mm, is vertically welded on tunger tube 2, main function is to be supported on middle packet backpack cover
On, it avoids wrapping in the insertion of exhaust pipe 3 too deep.
In use, support rod 1 is fixed on middle packet backpack cover by a bracket, exhaust pipe 3 is inserted into middle packet
200mm is deep.Argon gas is discharged into middle packet by the gas vent of rows of gas vent and both ends in 3 central axial direction of exhaust pipe,
Quickly air in middle packet can be discharged.
