Abstract
A novel eighteen-roller cold rolling mill comprises an upper working roller and a lower working roller. An upper side support and a lower side support are arranged on a strip inlet side and a strip outlet side of the working rollers respectively. The novel eighteen-roller cold rolling mill is characterized in that the upper side support is of a sectional structure, the lower side support is of an integral structure, at least five sections form the sectional structure of the upper side support, a microstroke adjusting device is arranged between a large-stroke adjusting device and the sections of the upper side support which is sectioned, a large-stroke adjusting balance cylinder is arranged on the large-stroke adjusting device, and a swing arm balance cylinder is arranged on a swing arm. The novel eighteen-roller cold rolling mill can be in a form that the lower side support is sectioned while the upper side support is of an integral structure. On the basis of a conventional eighteen-roller rolling mill, a working roller horizontal bending device is arranged, and a plate shape adjusting and controlling mechanism is added, so that capability, to adjust and control complex plate shape, of an existing eighteen-roller rolling mill is improved, and plate shape of produced strips is improved greatly; plate shape controlling capability is improved, so that the novel eighteen-roller cold rolling mill can be used for producing thinner strips, and application range of the eighteen-roller rolling mill is expanded.
Description
Technical field
The invention belongs to cold rolling of strip steel equipment.
Background technology
Roll the rolling quality of (material deformation drag is large) band to improve difficulty, when not increasing mill capacity, reducing working roll roller footpath is an approach well.But along with the reduction in working roll roller footpath, its lateral stiffness is just difficult to ensure, in large roll-force situation, roller system is difficult to keep stable.In order to stablizing of maintaining roller system, collateral support must be increased to working roll.Eighteen-high mill develops on the basis of six-high cluster mill based on above-mentioned principle.
Traditional eighteen-high mill does not have bearing block due to working roll, therefore does not have roller function compared to six-high cluster mill working roll, does 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.Because eighteen-high mill plate shape control measures are limited, therefore the plate shape of complexity is difficult to control.This is also that eighteen-high mill is relative to six-high cluster mill and the most significant shortcoming of mill.
Summary of the invention
For improving the ability of its regulation and control complex panel shape on the basis of traditional eighteen-high mill, the present invention proposes following technical scheme: a kind of 18 novel cold mills, comprise upper backup roll, upper intermediate calender rolls, top working roll and the bottom working roll corresponding with their positions, lower intermediate calender rolls, lower backing roll.Support on the upside of the band entrance side of top working roll and bottom working roll and outlet side are respectively equipped with and support with downside.Upside support supports with downside and is connected with the Long Distances adjusting device being fixed on frame both sides respectively.Its feature is: upside supports employing segmental structure and downside supports employing overall structure.The segmental structure quantity that upside supports is at least 5 pieces.Between the section block that Long Distances adjusting device and the upside that is segmented support, be provided with micro travel adjusting device, this micro travel adjusting device formed by the motor be fixed on above Long Distances adjusting device with in the leading section vertical core of Long Distances adjusting device with its reductor be linked in sequence, screw-nut pair, wedge i, spring and the side that matches with the wedge i wedge ii with projection.Long Distances adjusting device is equipped with Long Distances adjust compensating cylinder, the gap between upside support and micro travel adjusting device is eliminated by swing arm compensating cylinder 13.This 18 novel cold mills, also can adopt downside support segmentation and upside supports the integrally-built form of employing.
Adopt the 18 novel cold mills of technique scheme on the basis of traditional eighteen-high mill 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, thus the Strip Shape of production is greatly improved, because 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
Below in conjunction with accompanying drawing, the invention will be further described.
This 18 novel cold mills, comprise upper backup roll 1, upper intermediate calender rolls 2, top working roll 3 and the bottom working roll 4 corresponding with their positions, lower intermediate calender rolls 5, lower backing roll 6.Support 9 on the upside of the band entrance side of top working roll 3 and bottom working roll 4 and outlet side are respectively equipped with and support 10 with downside.Upside support 9 supports 10 with downside and is connected with the Long Distances adjusting device 8 be fixed on above frame 11 both sides respectively, and upside supports 9 employing segmental structures and downside support 10 adopts overall structure.The entrance side of top working roll 3 and the collateral support 9 of outlet side adopt segmentation structure, and segments is not less than 5 sections, determine based on working roll 3 length and the ability regulating and controlling plate shape.Every section of collateral support 9 can adjust separately along the displacement of rolling direction.The collateral support of entrance and exit controls in pairs, controls the displacement that every offside supports like this, top working roll 3 will be made to produce different curves in rolling direction, and then change the plate shape of band.Owing to controlling separately the curve just energy control panel shape of top working roll 3, therefore bottom working roll 4 does not need to carry out Discrete control, and the collateral support of bottom working roll 4 can adopt overall structure.In order to provide enough window space during roll change, collateral support is provided with the needs that Long Distances adjusting device 8 meets the adjustment of collateral support Long Distances.The independent fine setting of every section of collateral support 9 is then realized by the micrometric displacement adjusting device be contained on Long Distances adjusting device 8.The wedge i-17 that micrometric displacement adjusting device is driven by screw-nut secondary 16 moves up and down in the vertical core of Long Distances displacement adjusting device 8 leading section, wedge i-17 moves up and down and promotes the wedge ii-18 side-to-side movement of side with projection, namely the projection of wedge ii-18 side horizontally slips in the side opening of Long Distances displacement adjusting device 8 leading section, and then promotes collateral support 9 and produce displacement.Long Distances adjusting device 8 is equipped with Long Distances adjust compensating cylinder 12 and on micro travel adjusting device, be equipped with swing arm compensating cylinder 13, to eliminate the gap of screw mandrel and screw, displacement adjusting device and collateral support swing arm faying face.Gap between the screw mandrel of micrometric displacement adjusting device and screw is then eliminated by spring 19 fixing under wedge i-17.
In like manner, the entrance side of bottom working roll 4 and the collateral support 10 of outlet side adopt segmentation structure, and the collateral support 9 of top working roll 3 adopts overall structure also can reach the effect the same with such scheme equally.
The above; be only preferably detailed description of the invention of the present invention; but protection scope of the present invention is not limited thereto; all personnel being familiar with this method field, within the scope of method disclosed by the invention, are equal to replace or change according to method scheme of the present invention and design of the present invention thereof and all should be encompassed within protection scope of the present invention.
