Abstract
The utility model relates to a special-shaped foot roller of a continuous caser crystallizer, belonging to the field of spare parts of continuous casers. The utility model is characterized in that the central area is a convex drum body, and the two ends are cylinders. The utility model has the advantage that the convex drum body of the special-shaped foot roller can compress the blank casting shell to produce a bulging on the back part of the lower opening of the crystallizer so that the phenomena of corner cracking vertically of casting blanks and steel leaking caused by the bulging are avoided, and thereby, the quality of casting blanks and the operating rate of continuous casers are improved.
Description
The utility model is the sufficient roller of a kind of conticaster crystallizer abnormity, belongs to the spare part field of what conticaster.
Along with the development of continuous casting technology, it is found that the sufficient roller of existing conticaster crystallizer is the cylinder of same diameter, is fixed on the framework of crystallizer.By existing situation foot roller strand is only played support and guide effect, and the strand shell bulge of strand after going out the crystallizer end opening suppressed not enough, when strand shell bulge surpasses critical value, cause strand longitudinal corner crack even bleed-out.This phenomenon not only influences the quality of strand, and the grievous injury continuous casting installation for casting, influences the operating rate of conticaster, increases working strength of workers.
The purpose of this utility model is, by changing sufficient roll shape, limit the strand shell effectively and going out the bulge phenomenon that produces behind the crystallizer end opening, thereby avoid the strand shell longitudinal corner crack even the bleed-out phenomenon that cause thus, to reach quality that improves strand and the operating rate that improves conticaster.
For achieving the above object, the utility model is realized by following technology contents.Selecting for use middle low carbon steel or heat-resisting alloy steel to make pole at first as required, is that axis hole (3), central region convex shape drum body (1), two ends are the sufficient roller of conticaster crystallizer abnormity of cylinder (2) then with the pole center of being processed into.It is convex shape drum body that this abnormity foot roller also can be integral body, or the central area is a convex shape cylinder and two ends are the less cylinder of diameter.The paired sufficient roller of convex shape drum type abnormity is through on the turning cylinder, and is fixed on the crystalliser.When after the strand shell of casting goes out the crystallizer end opening, the bulge phenomenon occurring, this bulge is just being run into the convex shape drum body (1) of the central region of special-shaped sufficient roller, what is that convex shape drum body (1) has produced compression phenomena to strand shell bulge, therefore the development that has alleviated strand shell bulge, thereby prevent strand shell longitudinal corner crack and bleed-out phenomenon, the radius of curvature of its central region convex shape drum body (1) of the sufficient roller of conticaster crystallizer abnormity, the radius of two terminal circle cylinder (2) and the selection of length dimension are to select according to the shape and the specification of producing strand.
The utility model has the advantages that: the central region of the sufficient roller of this conticaster crystallizer abnormity is convex shape drum body or cylinder, and can compressing the strand shell, this convex shape drum body going out the bulge that produces behind the crystallizer end opening, alleviate the development of bulge, avoid the strand longitudinal corner crack and the bleed-out phenomenon that cause thus, thereby improved the quality of strand and the operating rate of conticaster.
Accompanying drawings embodiment of the present utility model.
Fig. 1, be the sufficient roller profilograph of conticaster crystallizer abnormity.
The concrete making of the sufficient roller of conticaster crystallizer abnormity is: at first make pole with middle low carbon steel, determine the radius and the length dimension of radius of curvature, two terminal circle cylinder (2) and the axis hole (3) of special-shaped sufficient roller central region convex shape drum body (1) then according to casting blank shape and specification, again by machined with pole by determining to be dimensioned to the sufficient roller of conticaster crystallizer abnormity.
Claims (2)
1, the sufficient roller of a kind of conticaster crystallizer abnormity is characterized in that: this abnormity foot roller central region is convex shape drum body (1), and two ends are Cylinder (2), roller central shaft hole (3).
2, the sufficient roller of conticaster crystallizer abnormity as claimed in claim 1 is characterized in that: this abnormity foot roller can be whole convex shape drum body or central region is the convex shape cylinder.
