Abstract
The utility model discloses a working roll for cold-rolling strip steel, comprising a roll body. The outer surface of the roll body is provided with a chromium-plated layer; and the surface of the chromium-plated layer is provided with a wear-resisting roughening layer. The working roll has the following advantages that 1, the surface of the chromium-plated layer is provided with the wear-resisting roughening layer, and the wear resistance is good, so that the surface quality of the rolled steel plate is good; and 2, due to the chromium-plated layer, the hardness of the working roll is increased, the generation of microcracks on the surface of the working roll is reduced, and the service life of the working roll is long.
Description
Technical field
The utility model relates to the cold rolling technology field, particularly a kind of cold-strip steel working roll.
Background technology
At present, when common cold roll uses,, on roll, produce scuffing and inhomogeneous impression easily owing to the steel plate edge stress is concentrated, friction is big, thus the product of the system broad that can't reroll, need frequent roll change, bring inconvenience to actual production.Simultaneously, this working roll stock removal is big, and the surface easily produces micro-crack, and service life is not long, and causes rolling plate surface quality poor.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of cold-strip steel working roll with excellent abrasive resistance, long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of cold-strip steel working roll, comprise roll body, and described roll body outer surface is provided with plating Chrome layer, and described plating Chrome laminar surface is provided with wear-resisting texturing layer.
The surface roughness of described wear-resisting texturing layer is 1.5～6 μ m.
The utility model adopts said structure, and have the following advantages: 1, Du Chrome laminar surface is provided with wear-resisting texturing layer, and its wearability well makes rolling plate surface quality good; 2,, Du Chrome layer has increased the hardness of this working roll, has reduced the generation of work roll surface micro-crack, the working roll long service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a structural representation of the present utility model;
In Fig. 1,1, roll body; 2,, Du Chrome layer; 3, wear-resisting texturing layer.
The specific embodiment
A kind of as shown in Figure 1 cold-strip steel working roll comprises roll body 1, and roll body 1 outer surface is provided with plating Chrome layer 2, and plating Chrome layer has increased the hardness of this working roll, has reduced the generation of work roll surface micro-crack.Gai is provided with wear-resisting texturing layer 3 in Du Chrome layer 2 surface.Wear-resisting texturing layer 3 adopts high-abrasive material, can be materials such as antifriction alloy, metal, cermet.
Wear-resisting texturing layer 3 adopts laser roughening, adopts blasting treatment on its surface, forms the texturing spike, the spike top of pruning then makes that the surface roughness of wear-resisting texturing layer 3 is 1.5～6 μ m, can improve roll service life, reduce roll change amount and roll consumption, improve milling train production efficiency; Can make simultaneously and the plate face flatness height of the steel plate that rolls out improve the fineness of belt steel surface and the aquatic foods degree of reflecting after the japanning.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
