Abstract
The utility model belongs to the mechanical field of material processing, relates to a part of a twenty high rolling mill in a cold rolling mill, in particular to a first intermediate roll of a twentyhigh rolling mill, which is characterized in that the end of a roll body is provided with a first taper and a second taper from the inside to the outside, and the taper value of the first taper is less than that of the second taper. The first intermediate roll shape with the two section-type taper not only avoids the sudden elastic flattening and elastic deformation of the edges of rolls, improves the rolling plate cut of the twenty high rolling mill, but also prevents the edge of the plate from generating high wave shape, controls the rolling edge wave to be within 10 to 50I-UNI, reduces thecross-section thickness difference of the steel plate to be rolled, makes the whole rolling process stable, smooth and high efficient, improves the plate cut quality of the steel plate with the edgeless than 250mm, and controls the cross-section thickness difference of the hard rolled coil with the thickness specification of 0.3mm to be within 12Mu, the cross-section thickness difference of thehard rolled coil with the thickness specification of 0.35mm to be within 15Mu and the cross-section thickness difference of the hard rolled coil with the thickness specification of 15mm to be within 20Mu.
Description
Technical field
The utility model belongs to the material processing machine field, relates in particular to a kind of cold rolling mill mill parts.
Background technology
The cold rolling great majority of present high grade silicon steel both domestic and external adopt mill to carry out reversible cold rolling, the mill first intermediate calender rolls roll shape technology is through the development in a nearly century, very ripe, but because rolling mill practice complexity, with high content of technology, and in the operation of rolling, can flatten and strain because the elastic problem of sheet material causes; For offsetting elastic flattening and the strain in the mill operation of rolling, some first intermediate calender rolls roll shapes are groped and developed in the company that uses the rolling cold-reduced sheet of mill in long-term production practice and research work, now be summarized as follows:
(1) domestic certain company's 20 roller silicon steel milling train list taperings, first intermediate calender rolls method
Use the rolling silicon steel of mill of work roll diameter 63mm, the first intermediate calender rolls diameter 102mm,, adopt the method that designs single tapering in the first intermediate calender rolls end, rolled out orientation, non-orientation silicon steel rolls hard volume in order to control and obtain good edge plate profile.But shortcoming is that lateral thickness difference is big, the high order wave type of limit portion is difficult to eliminate.
(2) the external Japanese firm single tapering first intermediate calender rolls method when the design multi-roll mill
Though Japan Patent JP2007144492A and set forth the tapering rolling of multi-roll mill at Chinese patents CN200610162568.9, but different single tapering first intermediate calender rolls that is to use that relates in the patent is controlled edge drop and edge plate profile, and edge drop control is applied on the UCM six roller tandem mills.
Above form generally is arranged to tapering (Taper) shape with first intermediate calender rolls in 20 rollers, its taper value=cone height h/ taper length l * 1000/1000=1～3 ‰ as shown in Figure 1; The advantage of this roll forming is that taper value is simple, grinding easily, and shortcoming is that tapering and cylinder transition position wear and tear easily, forms high order wave type easily.
The utility model content
The purpose of this utility model is to provide a kind of mill first intermediate calender rolls, this first intermediate calender rolls is provided with the double tapered section by the first intermediate calender rolls end at mill, with eliminate because of single tapering roller tapering and cylinder transition position easily the sheet material limit portion that causes of wearing and tearing the shortcoming of the unrestrained type of high order appears.
A kind of mill first intermediate calender rolls, the end of roll body is provided with first tapering and second tapering from inside to outside successively, and the taper value of described first tapering is less than the taper value of second tapering.
The taper value of described first tapering is 0.5～1.5 ‰, and the taper value of second tapering is 1.0～3.0 ‰.
Described first taper value is that 0.6 ‰, second taper value is 2.2 ‰.
The first intermediate calender rolls roll shape of the present utility model adopts the structure of two-part tapering, not only eliminating roller is the rapid elastic flattening of limit portion, strain, improved the rolling template of mill, and high order wave type can not appear in sheet material limit portion, the rolled edge wave is controlled in 10～50I-UNIT, reduced by the transverse thickness difference of rolled steel plate, the whole operation of rolling is stable, direct motion, efficiently, improved by the steel rolling edges of boards 250mm of portion with interior steel plate template quality, 0.3mm the hard volume lateral thickness difference that rolls of thickness specification is controlled in 12 μ, 0.35mm the hard volume lateral thickness difference that rolls of thickness specification is controlled in 15 μ, the hard volume lateral thickness difference that rolls of 0.5mm thickness specification is controlled in 20 μ.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 2, a kind of mill first intermediate calender rolls, the end of roll body is provided with first tapering and second tapering from inside to outside successively, the taper value h of first tapering
1/ l
1* 1000/1000 scope is 0.5～1.5 ‰, the taper value h of second tapering
2/ l
2* 1000/1000 scope is 1.0～3.0 ‰, and first taper value is arranged less than second taper value.
Be 65～85mm in work roll diameter during test, the first intermediate calender rolls diameter, 133～144mm, second intermediate calender rolls, 230～239mm, unit roll-force=0.30～0.60 (ton/mm) load mill on, selected first taper value=0.6 ‰, first intermediate calender rolls of second taper value=2.2 ‰ is implemented rolling, rolling template is good, particularly the rolled edge wave is controlled in 10～50I-UNIT, 0.3mm the hard volume lateral thickness difference that rolls of thickness specification is controlled in 12 μ, 0.35mm the hard volume lateral thickness difference that rolls of thickness specification is controlled in 15 μ, the hard volume lateral thickness difference that rolls of 0.5mm thickness specification is controlled in 20 μ.
