Description
Technical field
The utility model relates to continuous casting technology field, particularly a kind of chamfering foot-roller unit.
Background technology
Along with the development of continuous casting technology, sheet billet continuous casting product line is continually developed, the steel grade of production high-quality.Due in the molten steel of high-quality steel grade containing the element such as niobium, boron, this dvielement broadens steel grade the 3rd brittle zone, and at two cold bending sections and straightening section, strand bight temperature is easy to the brittle zone scope entering this kind of steel grade, causes producing strand transverse corner crack line.At present, part steel mill adopts band chamfering foot roller, and this sufficient roller supports more weak to leptoprosopy, and strand easily produces bulge, and strand bight easily produces longitudinal corner crack, has had a strong impact on the quality of strand.
Utility model content
The utility model provides one that strand can be avoided to produce bulge, eliminates the chamfering foot-roller unit of strand longitudinal corner crack.
For solving the problems of the technologies described above, the utility model provides a kind of chamfering foot-roller unit, for supporting chamfering continuous casting billet, comprising: roll body, back shaft, supporting seat, the first end cap and the second end cap.Described roll body is hollow ring structures; The arranged outside of described roll body has the groove matched with described chamfering continuous casting billet leptoprosopy, and the both sides of described groove are chamfering structure; The bottom of described groove is set to convex curvature, and described projection is parabolic shape; Described back shaft is through described roll body, and the two ends of described back shaft are fixed on described supporting seat by described first end cap and described second end cap respectively.
Further, described supporting seat is " U " font structure.
Further, the angle of inclination of described chamfering structure is 30 ~ 60 degree.
Further, the vertical range between described protruding peak and minimum point is 0.2 ~ 3mm.
Further, also comprise: bolt; The two ends of described back shaft are bolted on described first end cap and described second end cap respectively by described.
The chamfering foot-roller unit that the utility model provides, the arranged outside of roll body has the groove matched with chamfering continuous casting billet leptoprosopy, and the left and right sides of groove is chamfering structure; The bottom of groove is set to convex curvature, and convex curvature is parabolic shape.When applying, convex curvature can ensure that roll body fully contacts with the leptoprosopy of chamfering continuous casting billet, can effectively avoid chamfering continuous casting billet to produce bulge, eliminates chamfering continuous casting billet longitudinal corner crack, improves the quality of chamfering continuous casting billet.
Accompanying drawing explanation
The chamfering foot-roller unit structural representation that Fig. 1 provides for the utility model embodiment;
The bulge-structure schematic diagram that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
See Fig. 1, the utility model embodiment provides a kind of chamfering foot-roller unit, for supporting chamfering continuous casting billet 9.Described foot-roller unit comprises: roll body 5, back shaft 6, supporting seat 4, first end cap 1, second end cap 2 and bolt.Roll body 5 is hollow ring structures, and the arranged outside of roll body 5 has the groove matched with chamfering continuous casting billet 9 leptoprosopy.The left and right sides of groove is provided with chamfering 7, and the angle of inclination (the α angle namely in Fig. 1) of chamfering 7 is 30 ~ 60 degree (as 30 degree, 45 degree or 60 degree), and chamfering 7 requires that processing is smooth, and chamfering 7 vertex of surface place adopts circular arc excessive.
See Fig. 1 and Fig. 2, the bottom of groove is set to convex curvature 8, convex curvature 8 is parabolic shape, and the vertical range (the h height namely in Fig. 2) between convex curvature 8 peak and minimum point is 0.2 ~ 3mm (as 0.2mm, 1mm or 3mm).
See Fig. 1, supporting seat 4 is " U " font structure.Back shaft 6 is through roll body 5, and the two ends of back shaft 6 are fixed on supporting seat 4 by the first end cap 1 and the second end cap 2 respectively.Wherein, the two ends of back shaft 6 are respectively by being bolted on the first end cap 1 and the second end cap 2.
See Fig. 1, when applying the chamfering foot-roller unit that the utility model embodiment provides, the leptoprosopy of chamfering continuous casting billet 9 being placed in the groove on roll body 5, being supported by roll body 5 pairs of chamfering continuous casting billets 9.The chamfering foot-roller unit that the utility model embodiment provides, the arranged outside of roll body 5 has the groove matched with chamfering continuous casting billet 9 leptoprosopy, and the both sides of groove are chamfering structure.The bottom of groove is set to convex curvature 8, and convex curvature 8 is parabolic shape.When applying, convex curvature 8 can ensure that roll body 5 fully contacts with the leptoprosopy of chamfering continuous casting billet 9, can effectively avoid chamfering continuous casting billet 9 to produce bulge, eliminates chamfering continuous casting billet 9 longitudinal corner crack, improves the quality of strand.
It should be noted last that, above detailed description of the invention is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to example, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
