Abstract
The utility model relates to the field of section bars, in particular to a hard high-speed wire rolling mill roll collar. The hard high-speed wire rolling mill roll collar comprises a roll collar body. An inwards-sunken hole-type groove is formed in the portion, located in the middle of the axial direction, of the outer annular face of the roll collar body. Wear-resisting layers are welded to the outer annular face of the roll collar body and the outer surface of the hole-type groove respectively. The hard high-speed wire rolling mill roll collar has the advantages that due to the fact that the wear-resisting layers are arranged on the outer annular face of the roll collar body, the strength and wear resistance of the outer surface of the roll collar body are improved, the wear-resisting layers are formed by welding and can be repaired in a welding mode after efficacy is lost, it is ensured that workpieces can be recycled, and the service life of the roll collar is prolonged.
Description
Technical field
The utility model relates to section bar field, especially designs a kind of hard high-speed wire mill collars.
Background technology
Collars is mainly used in the production of high-speed rod, in high speed rolling mill rolling line steel processed, uses extensively, and be the chief component of high speed rolling mill.The quality of collars is mainly manifested in rigidity and its surperficial abrasion resistance of collars, the collars mode of production that wire rod production line uses at present can be divided into two kinds, whether be metallurgical binding according to the faying face of collars ectonexine, can be divided into mechanical bond and the large class of metallurgical binding two: mechanical bond comprises mechanical bonding, hot interference assembling method, cementing method; Metallurgical binding comprises hot isostatic pressing method, casting etc.But these two kinds of production methods all have different separately shortcomings.The mode of mechanical bond, bond strength is generally limited, cannot meet normal rolling requirement, and at present metallurgical binding is actual is a kind of casting, die casting mode, has sand holes, the defect such as loose, affects the surface quality of wire rod when production.Adopting this two kinds of collars that mode is produced simultaneously, all cannot carry out repairing and reusing using after wearing and tearing, scrap processing after can only being ground to certain size, is a kind of larger financial burden for Metallurgical Enterprise.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hard high-speed wire mill collars, has solved existing collars surface strength little, wears no resistance, and damages greatly the shortcoming that mortality is high in the process using.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of hard high-speed wire mill collars, comprise collars main body, the part that is positioned at axial centre on the outer ring surface of described collars main body is provided with the pass groove caving inward, and on described collars main body outer ring surface and on the outer surface of pass groove, is all welded with wearing layer.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described wearing layer is one or more alloy phases that add tungsten carbide, boron nitride, carbonization chromium powder on cobalt-based, Ni-based basis.
Further, the welding manner of described welding is solder brazing.
The beneficial effects of the utility model are: collars described in the utility model is provided with wearing layer at the outer ring surface of collars main body, intensity and the abrasion resistance of collars outer surface are increased, wearing layer is to be welded, can after losing efficacy, use repair by welding manner, workpiece is guaranteed can be recycled, and has increased the service life of collars.
Accompanying drawing explanation
Fig. 1 is the utility model structure side view;
Fig. 2 is the utility model structural front view.
In accompanying drawing, the list of parts of each label representative is as follows:
1, collars main body, 2, pass groove, 3, wearing layer, 4, outer ring surface.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1 and Figure 2, a kind of hard high-speed wire mill collars described in the utility model, comprise collars main body 1, the part that is positioned at axial centre on the outer ring surface 4 of described collars main body 1 is provided with the pass groove 2 caving inward, on the outer ring surface 4 of described collars main body 1 and on the outer surface of pass groove 2, be equipped with wearing layer 3, described wearing layer 3 is welded on the outer ring surface 4 and pass groove 2 of described collars main body 1, and the welding manner of described welding is solder brazing; Described wearing layer comprises carbide alloy phase, and described carbide alloy comprises cobalt-based, the binding metal such as Ni-based mutually; Described wearing layer 3 also comprises tungsten carbide, boron nitride, carbonization chromium powder alloy phase.
Collars 1 described in the utility model is provided with wearing layer 3 on collars main body outer ring surface 4 and pass groove 2, intensity and the abrasion resistance of collars main body outer surface are increased, wearing layer 3 is to be welded, can after losing efficacy, use repair by welding manner, workpiece is guaranteed can be recycled, and has increased the service life of collars.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. a hard high-speed wire mill collars, comprise collars main body, the part that is positioned at axial centre on the outer ring surface of described collars main body is provided with the pass groove caving inward, and it is characterized in that, on described collars main body outer ring surface and on the outer surface of pass groove, is all welded with wearing layer.
2. a kind of hard high-speed wire mill collars according to claim 1, is characterized in that, described wearing layer is one or more alloy phases that add tungsten carbide, boron nitride, carbonization chromium powder on cobalt-based, Ni-based basis.
