Abstract
The utility model relates to metallurgical rolling mechanical equipment, particularly to a roll ring used for a wire rolling mill; the outer surface of the roll ring is a working face, a key slot is formed on the inner surface of the roll ring, the metallographic structure of the working face adopts a Cr7C3 structure. The utility model solves the problem that shifting easily occurs in the prior roll rings, and forged steel rolls and centrifugal semi-steel rolls can be substituted by the roll ring, so that the manufacturing cost is reduced; moreover, by adopting the metallographic layer with the Cr7C3 structure, the use effect can be increased by 50 percent, the tensile strength of the working face is equal to or larger than 600 MPa, and the rigidity is between 60 to 80 HSD (Shore scleroscope hardness), thereby preventing the roll ring from shifting in the axial direction of the roll shaft.
Description
Technical field
The utility model relates to a kind of metallurgy rolling plant equipment, particularly the roll collars used of rod-rolling mill.
Background technology
In smelter, the roll collars that generally is used on the rod-rolling mill all adopts thrust step collars.This kind collars has the thrust step in single side face, and fixedly the position of collars still can not suppress collars to the other direction play.
The utility model content
The technical problems to be solved in the utility model is: the problem at play easily takes place in the existing collars provides a kind of collars that prevents play.
In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical problem adopts and is: a kind of collars, collars outer surface are working face, are provided with keyway at the inner surface of collars.
According to another embodiment of the present utility model, the metallurgical structure that further comprises described working face is Cr
7C
3Institutional framework.
The utility model has solved the defective that exists in the background technology, alternative forged steel roll of the utility model and centrifugal ferrosteel roll, and production cost reduces, the Cr of employing
7C
3The metallographic layer of institutional framework can make result of use improve 50%, and the tensile strength of working face is more than or equal to 600MPa, and hardness can be avoided the axial generation play of collars at roll shaft in 60～80HSD (Shore hardness).
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, collars, 2, keyway.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Structure of the present utility model as shown in Figure 1, the outer surface of collars 1 is Cr for the working lining structure
7C
3Structure, Cr
7C
3Structure is a kind of metallurgical structure of high-hardness, wearable, and the working time of collars is prolonged significantly, and steel transportation amount is increased to original 2-3 doubly.The collars outer surface is a working face, is provided with keyway 2 at the inner surface of collars, and collars keyway 2 cooperates fixing with the key of roll shaft.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (2)
1, a kind of collars is characterized in that: on the collars surface working face is arranged, keyway is arranged in collars.
2, collars as claimed in claim 1 is characterized in that: the structure that described working face adopts is Cr
7C
3Institutional framework.
