Description
Technical field
Big cross section continuous-casting art in being produced the present invention relates to steel, the special dummy ingot of specifically a kind of continuous casting ellipse base
Head.
Background technology
With the development of steel and iron industry, user to steel products quality requirement more and more higher, get over by the blank requirement to strand
Come higher.Slab steel have been widely used the fields such as ship, building, military project, and the thickness that slab blank needs is more and more thicker.
In the past, the production for the extra-thick plate blank of big cross section was mostly to use die casting, and the billet quality of this method production is poor, and produces
Efficiency is low.Nippon research and development, extra-thick plate blank vertical casting machine can be produced by having gone into operation, and blank maximum gauge is reachable
600mm。
In recent years, efficient, high quality special heavy plate blank is produced by oval base continuous cast method becomes reality, and blank is most
Big thickness is up to 900mm.Because the shape of oval base belongs to special-shaped and section is big, differed greatly with conventional continuous casting, prior art
In dummy bar head be not adapted with the crystallizer of oval base, and seal dummy ingot complex operation, easy bleed-out, process of billet withdrawal is unstable
It is fixed.
The content of the invention
In order to overcome the shortcomings of that existing dummy bar head and the crystallizer of oval base are not adapted, the invention provides one kind even

Further, the first arc transiting surface, the second inclined plane and are provided between the first inclined plane and the second inclined plane
The second arc transiting surface is provided between three inclined planes, the area of the first inclined plane is more than the area of the second inclined plane and the 3rd and tilted
The area sum in face, the area of the second inclined plane are more than the area of the 3rd inclined plane.
Further, groove is set along the oval short axle, and along the direction of the short axle, the length of groove is grown for the short axle
The half of degree, the position correspondence of groove is in the second inclined plane and the 3rd inclined plane.
Further, groove includes groove exocoel and groove inner chamber, and groove exocoel and groove inner chamber are along the ellipse
Heart line direction is set gradually and groove inner chamber is between groove exocoel and connecting portion, is contained along the direction groove inner chamber of the short axle
The inner of fluted inner chamber and the outer end of groove inner chamber, groove inner chamber pass through the outer end of groove inner chamber and groove exocoel and the dummy ingot
The ft connection of head, the volume of groove exocoel are less than the volume of groove inner chamber, the direction of the major axis oval along this, groove exocoel
Width be less than groove inner chamber width.
Further, the entrance of groove exocoel is located in the second inclined plane, and the outer end of groove inner chamber is located at the 3rd inclined plane
And second inclined plane and the 3rd inclined plane connection intermediate location, and the entrance of the outer end of groove exocoel and groove inner chamber connects
It is logical.
Further, groove inner chamber is tapered, and the top of the taper is the inner of groove inner chamber, and the bottom of the taper is recessed
The outer end of groove inner chamber, groove exocoel are surrounded by wall surface and two side walls being parallel to each other, and the oval center line is located at
In wall surface, the intersection between the first inclined plane and the second inclined plane also is located in wall surface, the inner of groove inner chamber and bottom wall
Face is concordant.
Further, lifting through hole is additionally provided with connecting portion, lifting through hole is arranged at intervals with being connected through hole.
The invention has the advantages that dummy ingot portion is arranged into oval platy structure, the degree of lip-rounding can be gone out with crystallizer
Shape is adapted, and groove is set in dummy ingot portion, you can meet the connection request of base head and the special dummy bar head of continuous casting ellipse base,
Deingot device is facilitated to disengage base head and dummy bar head.
