Slided up and down under the driving of shape adjustment mechanism hydraulic cylinder along memorial archway.The following is the specific descriptions on each assembling or mechanism：
（1）Collateral support assembling and stripper back lining bearing supporting construction
Due to eighteen-high mill when rolling the high-intensity band steels such as silicon steel, stainless steel and special steel, it is necessary to using less work
Roller diameter, and with the reduction of roll neck, the horizontal deflection of working roll substantially increases, horizontal rigidity is obviously reduced, to Strip Shape Control
Have a significant impact, therefore the present invention reduces the horizontal deflection of working roll by designing lateral support and working roll moving horizontally, and enters
And increase the horizontal rigidity of working roll.Specifically, exactly by the way that working roll both sides are set up with collateral support, the present embodiment it is collateral
Support is divided into two parts, and one of them is collateral support assembling, and it is arranged above the side of horizontal support rollers, is by sectional back lining bearing
On an axis, it ensure that support force is sufficiently large by multi-point support, while also in whole backing cloth bearing roller（By multiple
Back lining bearing is co-axially mounted）It is upper to be provided with suitable roll shape curve, it is ensured that along barrel length omnidirectional support horizontal support rollers, to enter
And support works roller reduces the horizontal deflection of working roll.Whole backing cloth bearing roller is arranged in the support beam of side, is passed by band displacement
The Driven by Hydraulic Cylinder of sensor, can adjust the position of backing cloth bearing roller, while being also suitable for work according to the change of work roll diameter
As roller move horizontally after position adjustment；Another is stripper back lining bearing supporting construction, and stripper can be along slip
Slide key on liner plate slides back and forth, and whole stripper passes through hydraulic cylinder（With displacement transducer）Control its advance or after
The position moved back, is arranged in the backing cloth bearing roller support level support roller of stripper front end, big on working roll when carrying rolling
Part of horizontal power, same stripper can also adapt to moving horizontally for working roll, provide working roll servo-actuated support.Above two
The horizontal deflection that collateral support is provided to reduce working roll is planted, but its stress size differs widely, due to level on working roll
The direction of power is smaller with crossing steel wire angle, therefore stripper back lining bearing supporting construction（Closer to steel wire excessively）By horizontal force more
Greatly, thus thereon back lining bearing should have bigger bearing capacity, and the back lining bearing of collateral support fit on just carries small by one
A bit, so two kinds of back lining bearing sizes can select different type（Also can be identical）, so as to cost-effective.Collateral support is assembled and anti-
Twine the back lining bearing in guide plate back lining bearing supporting construction have damage need replacing when, it is only necessary to it is collateral support assembling driving hydraulic pressure
Cylinder and stripper driving hydraulic cylinder return to roll change position, and intermediate calender rolls assembling is lifted to roll change position, at this moment changed by backing roller
Roller apparatus directly hauls out the backing roller for needing to change back lining bearing, and without whole side, all hauling-out is more sliding, and roll change is more
It is targetedly and convenient and free, it is time saving and energy saving, improve operating efficiency.
（2）Working roll roller box structure
Working roll roller box structure includes transmission side and operates side shaft holder, working roll, horizontal support rollers and be arranged on bearing block
Contact force adjusting device.The concrete principle for contacting force adjusting device is as follows：Stop block, pull bar are designed with bearing block（One end
There is screw thread）It is connected to through stop block on bearing block, compression spring is installed on pull bar（But also other elastic components）, pass through spiral shell
Female cooperation with screw thread on pull bar makes spring be pressed in advance in the middle of stop block and nut, and elongated hole, water are provided with working roll bearing block
Flat supporting roller bearing seat can be slided along elongated hole, and the size of pre-pressure of the spring can be thus controlled by the position of adjusting nut,
Ensure that horizontal support rollers keep contacting and support works roller with the working roll moment.When needing to change working roll, whole working roll
Roller box is drawn out frame along changing track for roll, unclamps nut, allows horizontal support rollers and working roll roll surface to have certain interval, be convenient for changing
Working roll.Be that working roll devises horizontally moving functions to further reduce working roll horizontal force, by it is collateral support assembling and
Stripper back lining bearing support level support roller, promotes whole working roll roller box to slide into presetting position, then ensures
Working roll is stepped up by the collateral support of both sides, then starts belt steel rolling.The level that working roll roller box structure adds working roll is firm
Degree, while horizontal force is reduced by moving horizontally, to ensure that smoothly rolling creates good condition.
（3）Wedge-shaped adjustment mechanism
Eighteen-high mill is when being rolled, due to supplied materials band deformed steel strip, when and wedge-shaped band occurs（Supplied materials is along cross-section
Face thickness of two sides difference is larger）, the adjustment for having an angle of inclination to working roll is now needed, that is, the roller that inclines regulation, to improve into
Product plate shape, when working roll has the roller that inclines to adjust, horizontal support rollers are commonly mounted on unified bearing block with working roll, so
Now horizontal support rollers can also tilt certain angle, if backing cloth bearing roller be servo-actuated tilt, such working roll along the body of roll just
It can not be completely supported, when being acted on by horizontal force, working roll will be broken, produce production accident, serious shadow
Ring production efficiency.In order to avoid the generation of such a accident, the present invention devises a kind of wedge-shaped adjustment mechanism, when supplied materials is clapboard
During material, working roll, horizontal support rollers and backing cloth bearing roller can be tilted synchronously, it is ensured that the comprehensive support of the working roll body of roll.Specifically
Pass through the driving hydraulic cylinder of wedge-shaped adjustment mechanism（Band displacement transducer）Slip lining motion is promoted, slip lining is now installed on
On stripper moved therewith with lateral support structure, transmission side slip lining and fore side slip lining can individually adjust slip
Distance, so as to correspond to fascinating for working roll so that working roll obtains good horizontal side support.This design structure is succinct, can grasp
The property made is strong, reduces the generation of fracture of roller accident.
（4）Intermediate calender rolls are assembled and other structures
Present invention design intermediate calender rolls can axial float, reduce roll harmful contact area, reduce strip side portion and be thinned, while middle
Roller is designed with positive and negative roller, can better control over plate shape.On screwdown gear, backing roll assembling and rolling line adjusting device and one
As milling train it is similar, the present invention is repeated no more.
The problem of this eighteen-high mill solves working roll horizontal deflection well so that change back lining bearing more time saving
It is laborsaving, while adding wedge-shaped adjustment mechanism, the problem of working roll is easily broken off is solved, while good profile is ensured,
The security reliability of equipment is improved again, cost is reduced, and promotion prospect is wide.
