Abstract
A kind of 18 cold mills, including upper and lower working roll.The band entrance side of working roll and outlet side are respectively equipped with upside and support and downside support.Its feature is: upside supports employing segmental structure and downside supports and uses overall structure.The segmental structure quantity that upside supports is at least 5 pieces.It is provided with micro travel adjusting apparatus between the section block that big adjusting device for travel and the upside that is segmented support.Equipped with big Traffic control system compensating cylinder equipped with swing arm compensating cylinder in swing arm micro travel adjusting apparatus on big adjusting device for travel.This 18 cold mills, it is possible to support segmentation and upside on the downside of employing and support and use integrally-built form.The present invention tradition eighteen-high mill on the basis of by arranging working roll horizontal curvature device, add plate shape regulating and controlling mechanism, and then improve the ability of existing eighteen-high mill regulation and control complex panel shape, so that the Strip Shape produced is greatly improved, owing to Strip Shape Control ability improves, and then may be used for producing thinner band, expand the range of application of eighteen-high mill.
Description
Technical field
The invention belongs to cold rolling of strip steel equipment.
Background technology
Roll the rolling quality of (material resistance of deformation is big) band in order to improve difficulty, roll not increasing
In the case of function power, reducing working roll roller footpath is an approach well.But along with working roll
The reduction in roller footpath, its lateral stiffness is just difficult to ensure that, in the case of big roll-force, roller system is difficult to
Keep stable.For stablizing of maintaining roller system, it is necessary to working roll is increased collateral support.18 rollers
Milling train is namely based on what above-mentioned principle developed on the basis of six-high cluster mill.
Traditional eighteen-high mill does not has bearing block due to working roll, therefore compared to six-high cluster mill work
There is no roller function as roller, do not possess the ability by work roll bending adjustment plate shape.Its plate shape
Control measures are only limitted to the positive roller of intermediate calender rolls and intermediate roll shifting.Owing to eighteen-high mill plate shape is adjusted
Control means are limited, therefore are difficult to control for complicated plate shape.This is also eighteen-high mill phase
Shortcoming the most significant for six-high cluster mill and mill.
Summary of the invention
For improving the ability of its regulation and control complex panel shape on the basis of tradition eighteen-high mill, this
Bright proposition techniques below scheme: a kind of 18 cold mills, including upper backup roll, upper intermediate calender rolls,
Top working roll and the bottom working roll corresponding with they positions, lower intermediate calender rolls, lower backing roll.
The band entrance side of top working roll and bottom working roll and outlet side be respectively equipped with upside support with under
Collateral support.Upside supports to support with downside and fills with the big Traffic control system being fixed on frame both sides respectively
Put connected.Its feature is: upside supports employing segmental structure and downside supports and uses entirety
Structure.The segmental structure quantity that upside supports is at least 5 pieces.At big adjusting device for travel and quilt
It is provided with micro travel adjusting apparatus, this micro travel adjusting apparatus between the section block that the upside of segmentation supports
By the motor being fixed on above big adjusting device for travel with in the leading section of big adjusting device for travel
The reductor that is linked in sequence with it in vertical core, screw-nut pair, wedge i, spring and with tiltedly
The side that wedge i matches is formed with protruding wedge ii.Big adjusting device for travel is joined
Have big Traffic control system compensating cylinder, equipped with swing arm compensating cylinder in micro travel adjusting apparatus.
Use the 18 novel cold mills of technique scheme on the basis of tradition eighteen-high mill
On by arranging working roll horizontal curvature device, add plate shape regulating and controlling mechanism, and then improve
The ability of existing eighteen-high mill regulation and control complex panel shape, so that the Strip Shape produced is greatly
Improve, owing to Strip Shape Control ability improves, and then may be used for producing thinner band, expand
The range of application of eighteen-high mill.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
This 18 cold mills, including upper backup roll 1, upper intermediate calender rolls 2, top working roll 3
And the bottom working roll 4 corresponding with they positions, lower intermediate calender rolls 5, lower backing roll 6.On
The band entrance side of working roll 3 and bottom working roll 4 and outlet side be respectively equipped with upside support 9 with
Downside supports 10.Upside support 9 with downside support 10 respectively be fixed on frame 11 both sides
The big adjusting device for travel 8 of top is connected, and upside supports 9 employing segmental structures and downside supports
10 use overall structure.The entrance side of top working roll 3 and the upside of outlet side support 9 employings
Segmentation structure, segments is not less than 5 sections, based on working roll 3 length and the energy of regulation and control plate shape
Depending on power.The upside support 9 of every section can individually adjust along the displacement of rolling direction.Entrance and
Outlet side supports and controls in pairs, so controls the displacement that every offside supports, will make work
Roller 3 produces different curves in rolling direction, and then changes the plate shape of band.Due to individually control
The curve of top working roll 3 processed just energy panel shape, therefore bottom working roll 4 is made without segmentation control
System, the downside of bottom working roll 4 supports 10 can use overall structure.In order to provide foot during roll change
Enough window space, upside support 9 is provided with big adjusting device for travel 8 and meets the big stroke of collateral support
The needs adjusted.The upside of every section supports the individually fine setting of 9 then by being contained in big Traffic control system dress
The micro travel adjusting apparatus 7 put on 8 realizes.Micro travel adjusting apparatus 7 passes through screw-nut
The secondary 16 wedge i-17 driven in the vertical core of big travel displacement adjusting apparatus 8 leading section on move down
Dynamic, wedge i-17 moves up and down the wedge ii-18 side-to-side movement promoting side with projection, i.e.
The projection of wedge ii-18 side is left and right in the side opening of big travel displacement adjusting apparatus 8 leading section
Slide, and then on the upside of promotion, support 9 generation displacements.On big adjusting device for travel 8 equipped with
Big Traffic control system compensating cylinder 12 and equipped with swing arm compensating cylinder 13 in micro travel adjusting apparatus 7,
To eliminate the gap of screw mandrel and screw, micro travel adjusting apparatus and collateral support swing arm faying face.Micro-
Gap between the screw mandrel of adjusting device for travel 7 and screw is then by spring fixing under wedge i-17
19 eliminate.
In like manner, if supporting 10 employing segmentations on the downside of the entrance side of bottom working roll 4 and outlet side
Formula structure, and the upside of top working roll 3 supports 9 employing overall structures and also can reach equally with upper
The effect that scheme of stating is the same.
The above, the only preferably detailed description of the invention of the present invention, but the protection of the present invention
Scope is not limited thereto, and all is familiar with the personnel in this method field in method disclosed by the invention
In the range of, the design of the method according to the invention scheme and the present invention thereof equivalent in addition or change
Change all should be contained within protection scope of the present invention.
