Abstract

The utility model discloses a roller, which comprises a connection shaft segment I (1), a connection shaft segment II (4) and an operation shaft segment (2) between the connection shaft segment I (1) and the connection shaft segment II (4), which are integrated, one layer of composite alloys (3) are arranged on the surface of the outer periphery of the operation shaft segment (2), the axial length of the composite alloys (3) is equal to that of the operation shaft segment (2). The utility model has the advantages of strong abrasive resistance, high temperature resistance, and greatly improved actual use service life of the roller.

Description

Roll

Technical field:

The utility model relates to the roll that a kind of rolling section bar is used.

Background technology:

Steel rolling producer uses the rolling various wire rods of roll, in the process such as bar and seamless steel pipe, roll all will be in high temperature, work under high load capacity and the high-speed condition, its applying working condition condition is abominable completely, so just require the working face of roll must have high wearability and characteristic such as high temperature resistant, but, because the roll of steel rolling producer use at present generally all is adopted as common iron, for common iron, both made before use it had been carried out correspondingly heat treatment, its wearability and high-temperature stability also are difficult to satisfy above-mentioned requirements, therefore cause shorten dramatically the actual life of roll.

The utility model content:

The technical problems to be solved in the utility model is, provides a kind of wearability strong, high temperature resistant, can improve the roll in service life greatly.

Technical solution of the present utility model is that a kind of roll with following structure is provided: it comprises and connects shaft part I, connects shaft part II and connecting shaft part I and the work shaft part that is connected between the shaft part II; Described connection shaft part I, connection shaft part II and work shaft part are as a whole; The external peripheral surface of described work shaft part is provided with one deck composite alloy.

After adopting above structure, compared with prior art, the utlity model has following advantage: because the utility model is provided with one deck composite alloy at the work shaft part of roll, we know, composite alloy has very strong high temperature resistant and antiwear characteristic, and therefore, the utility model in use, can directly utilize composite alloy to contact, thereby improve greatly actual life of the present utility model with processed section bar.

Description of drawings:

Fig. 1 is the structural representation of the utility model roll.

Fig. 2 is the main TV structure schematic diagram of the utility model roll.

Fig. 3 is the sectional structure schematic diagram along " A-A " line among Fig. 2.

Shown in the figure, 1, connect shaft part I, 2, the work shaft part, 3, composite alloy, 4, connect shaft part II.

The specific embodiment:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

As Fig. 1, Fig. 2 and shown in Figure 3, in this specific embodiment, the utility model roll comprises and connects shaft part I1, connects shaft part II4 and connecting shaft part I1 and the work shaft part 2 that is connected between the shaft part II4; Described connection shaft part I1, connection shaft part II4 and work shaft part 2 are as a whole; The external peripheral surface of described work shaft part 2 is provided with one deck composite alloy 3; The axial length of described composite alloy 3 equals the axial length of work shaft part 2, the whole external peripheral surface that composite alloy 3 axial lengths equal the work that the is arranged so that shaft part 2 of work shaft part 2 axial lengths can be wrapped by composite alloy 3, thereby guarantee that effectively work shaft part 2 is in entire work process, composite alloy 3 can both contact with being rolled section bar, further improves greatly actual life of the present utility model.

Claims

1. roll, it comprises and connects shaft part I (1), connects shaft part II (4) and be positioned at and connect shaft part I (1) and the work shaft part (2) that is connected between the shaft part II (4); Described connection shaft part I (1), connection shaft part II (4) and work shaft part (2) are as a whole, and it is characterized in that: the external peripheral surface of described work shaft part (2) is provided with one deck composite alloy (3).
