Abstract
The utility model relates to a four-high mill with two roughness working rolls, including two backing rolls one on top of the other, be equipped with a pair of working roll between two backing rolls, the roughness of working roll interlude is 0.01 mu m, and the roughness of working roll both ends section is 0.4 mu m. The utility model discloses simple structure, reasonable in design adopts two roughness working rolls can avoid aluminum product mirror surface fabric rolling in-process working roll and backing roll to take place to skid and cause mirror surface material surface to produce fine and close striae, improves mirror surface fabric quality, satisfies the customer demand.
Description
Technical Field
The utility model relates to a rolling mill field, especially a four-high mill with two roughness work rolls.
Background
The aluminum mirror surface material has high requirement on the surface roughness of a working roll of a rolling mill, the surface roughness of the working roll is generally 0.01 mu m, but the surface roughness of the working roll is low, so that slipping is easily generated between the working roll and a supporting roll in the actual rolling process, and fine transverse striations are formed to influence the product quality.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a four-high mill with two roughness working rolls avoids the rolling in-process of mirror surface material to produce smooth and fine striations, improves mirror surface material quality.
The utility model discloses a following scheme realizes: a four-roller rolling mill with double-roughness working rollers comprises two supporting rollers which are arranged one above the other and one below the other, a pair of working rollers is arranged between the two supporting rollers, the surface roughness of the middle section of each working roller is 0.01 mu m, and the surface roughness of the two end sections of each working roller is 0.4 mu m.
Further, the length of the middle section with the surface roughness of the working roll being 0.01 mu m is 1250 to 1300mm.
Further, the length of each end section with the surface roughness of 0.4 mu m of the working roll is 270 to 350mm.
Further, the surface roughness of the support roller is 0.04 μm.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses simple structure, reasonable in design adopts two roughness working rolls can avoid aluminum product mirror surface fabric rolling in-process working roll and backing roll to take place to skid and cause mirror surface material surface to produce fine and close striae, improves mirror surface fabric quality, also realizes the increase of speed simultaneously, and production speed is improved to 60m/min by original 30m/min, and the increase of speed 100%.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to specific embodiments and related drawings.
Drawings
FIG. 1 is a schematic diagram of the overall structure of an embodiment of the present invention;
FIG. 2 is a schematic view of the construction of a work roll according to an embodiment of the present invention;
the reference numbers in the figures illustrate: 100-supporting rolls, 200-working rolls, 210-middle sections, 220-two end sections and 300-aluminum materials.
Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure herein. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As shown in 1~2, a four-high mill with double roughness work rolls comprises two support rolls 100 arranged one above the other and one below the other, a pair of work rolls 200 is arranged between the two support rolls, the surface roughness of the middle section 210 of each work roll is 0.01 μm, and the surface roughness of the two end sections 220 of each work roll is 0.4 μm; because the roughness of the two end sections of the working roll is larger, when the two end sections of the working roll and the two end parts of the supporting roll work in a matching way, the slipping between the working roll and the supporting roll can be avoided, and the middle section of the working roll rolls the aluminum material to produce the mirror fabric meeting the requirements of customers; the utility model discloses a two roughness working rolls can avoid aluminum product mirror surface fabric rolling in-process working roll and backing roll to take place to skid and cause mirror surface material surface to produce fine and close striae, improve mirror surface fabric quality.
In the embodiment, the intermediate section with the surface roughness of the working roll of 0.01 mu m is 1250-1300 mm in length.
In the embodiment, the length of each end section with the surface roughness of the working roll being 0.4 mu m is 270 to 350mm.
In this embodiment, the support roller surface roughness is 0.04 μm.
Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effects which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.
The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using a bolt or screw connection) can also be understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).
In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.
The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
