Description
Technical field
The utility model relates to Ferrous Metallurgy production field more particularly to a kind of casings applied to continuous casting tundish
Centralising device.
Background technique
Currently, iron and steel metallurgical industry high temperature molten steel solidification forming mode have molding (high-temperature molten steel is poured into steel ingot,
Steel billet is machined to through blooming mill or forging and stamping) and continuous casting (high-temperature molten steel is directly poured into continuous casting steel billet) two ways, and continuous casting
Recovery rate of iron can be improved in mode, production cost is reduced, so generally being used by each iron and steel metallurgy enterprise.
The conticaster is a kind of machine that liquid molten steel is directly poured into solid-state steel billet, and capital equipment is turned by ladle, ladle
Platform, tundish car, tundish, plug rod mechanism, crystallizer, bobbing machine, secondary spraying device, withdrawal straightening machine, dummy bar, cutting are set
The part such as standby, knockout mechanism, water cooling live-roller forms.Molten steel be diverted in crystallizer cooling down by tundish.
When carrying out shunting molten steel, to guarantee that molten steel is not contacted with oxygen, protective casting is carried out using intermediate canning tube.Meanwhile in order to
Ensure the uniformity of molten steel distribution, it is desirable that intermediate canning tube is in the center of crystallizer.
Since the position of crystallizer is fixed, and store tundish tundish car can up and down, front and rear, left and right into
Row movement, so that making the position for the tundish being mounted on tundish car can also accordingly be moved, it is necessary to ensure that intermediate
Canning tube is in the center of crystallizer, and since the inner cavity of crystallizer is rectangular, rectangle or circle, and intermediate canning tube is
Circle, in addition the diameter of intermediate canning tube is far smaller than crystallizer internal cavity size, this results in intermediate canning tube and is difficult alignment knot
The inner cavity of brilliant device, although can have by the way that the continuous movement of tundish car to be adjusted to position, and by ruler to realize centre
Canning tube is in the center of crystallizer for intermediate canning tube centering, but due to lacking the intuitive reference substance of comparison, in addition intermediate
Canning tube centering operation takes a long time, so that molten steel waiting time is long, causes molten steel composition to act improperly, causes mass loss.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of intermediate canning tube by examining to scene
With centralising device, which can simplify the centering operation of intermediate canning tube, improve the speed and precision of intermediate canning tube centering.
A kind of intermediate canning tube centralising device of the utility model, specific structure are as described below:
A kind of intermediate canning tube centralising device, including intermediate canning tube and crystallizer internal cavity, it is characterised in that:
The crystallizer internal cavity is provided with boss component in a pair at end opening on it, passes through the centering boss component
Intermediate canning tube is centered in the center of crystallizer internal cavity.
A kind of intermediate canning tube centralising device according to the present utility model, which is characterized in that the centering boss group
Part includes two pieces of semicirculars in shape and symmetrical boss face, and the center of the diameter line of two pieces of boss faces offers half slot, and two pieces
Boss face is opposite to merge one circular boss of formation, and the opposite merging of half slot then forms a circular through hole at two, in boss face
Bottom surface offer annular protrusion, the outer diameter of the annular protrusion and internal diameter (or the lumen width) of crystallizer internal cavity are corresponding.
It should be noted that crystallizer internal cavity has round and rectangular, if crystallizer internal cavity is circle, then annular protrusion is just caught in knot
Brilliant device inner cavity, as crystallizer internal cavity be it is rectangular, then the annular protrusion is also the width direction for being just caught in crystallizer internal cavity, guarantee
Centering effect.
A kind of intermediate canning tube centralising device according to the present utility model, which is characterized in that half slot at described two
The opposite center for merging the circular through hole formed and being located at entire centering boss component, intermediate canning tube pass through the circular through hole
The center of crystallizer internal cavity is entered back into, and the diameter of the circular through hole is allowed equal to outer diameter+technique of intermediate canning tube
Casing centering minimum deviation value.
Using the utility model a kind of intermediate canning tube with centralising device obtain it is following the utility model has the advantages that
(1) a kind of intermediate canning tube centralising device of the utility model, structure is simple, easily manufactured, simplifies pair
Middle operation；
(2) a kind of intermediate canning tube centralising device of the utility model can improve intermediate canning tube centering speed and essence
Degree.
Detailed description of the invention
Fig. 1 is a kind of concrete structure schematic diagram of intermediate canning tube centralising device of the utility model；
Fig. 2 is a kind of top view of intermediate canning tube centralising device of the utility model；
In figure: canning tube among 1-, 2- crystallizer internal cavity, 3- centering boss component, 3a- boss face, 3b- half slot,
3c- annular protrusion.
Specific embodiment
A kind of intermediate canning tube of the utility model is made further of centralising device with reference to the accompanying drawings and examples
Description.
Embodiment
As shown in Figure 1, a kind of intermediate canning tube centralising device, including intermediate canning tube 1 and crystallizer internal cavity 2, the knot
Brilliant device inner cavity is provided with boss component 3 in a pair at end opening on it, by the centering boss component by intermediate canning tube pair
In in the center of crystallizer internal cavity.
Centering boss component 3 includes two pieces of semicirculars in shape and symmetrical boss face 3a, in the diameter line of two pieces of boss faces
The heart offers half slot 3b, and two pieces of boss faces are opposite to merge one circular boss of formation, and half slot merges then relatively at two
A circular through hole is formed, offers annular protrusion 3c, outer diameter and the crystallizer internal cavity 2 of the annular protrusion in the bottom surface of boss face
Internal diameter (or lumen width) is corresponding.
Crystallizer internal cavity has round and rectangular, and if crystallizer internal cavity is circle, then annular protrusion is just caught in crystallizer
Chamber, as crystallizer internal cavity be it is rectangular, then the annular protrusion is also the width direction for being just caught in crystallizer internal cavity, ensure that centering
