The specific embodiment

Below in conjunction with accompanying drawing the present invention is described further

As shown in Figure 1, the present invention by rolling-mill housing assembling 1, AGC cylinder fixture 2, working roll roller be 3, the intermediate calender rolls roller is 4, the backing roll roller is 5, work roll bending 6, intermediate calender rolls is traversing and roller 7, backing roll balance 8, wedge balancing controls 9, milling train in mechanisms such as roll change track 10, lower support roller locking device 11, thruster cylinder 12 form.This milling train two-chip computer frame connects by entablature, the frame bottom is fixed on the rolling mill base, there is working roll to reach in the gantry operation side, lower support roller locking device 11, after new roll is changed roll is locked, prevent that roll from producing axial displacement under the effect of roll-force, on, the side inlet side of lower support roll bearing seat has thruster cylinder 12, treat new roller replacing, after the locking device locking, the thruster cylinder promotes backing roll deflection outlet side, the skew that the center of intermediate calender rolls roller system and frame central have 4mm, intermediate calender rolls roller system deflection entrance side, rolling stability improves in the roll roller system of interlaced arrangement.

As shown in Figure 3, the backing roll bascule is installed in traversing 14 of the milling train intermediate calender rolls, and the diameter of hydraulic cylinder is reduced to ￠ 90 by the ￠ 200 of original structure, and this structure is very compact, has reduced weight of equipment, has saved investment.And backing roll bascule of the prior art, employing be the suspension type structure, this device is upwards mentioned backing roll by being lifted on the hydraulic cylinder on the milling train platform, reaches the purpose of balance

As shown in Figure 4, traversing cylinder 15 heads are fixed on the frame in the traversing structure of intermediate calender rolls, and cylinder body is along with traversing beam 17 is mobile and traversing, and the displacement transducer 16 of hydraulic cylinder afterbody is convenient to maintenance and replacing in the outside of traversing cylinder 15.And do not improve pre-structure, and traversing cylinder afterbody is fixed on the rolling-mill housing, and displacement transducer is installed in the base, in case sensor damages when needing to change, needs traversing cylinder and associated components complete removal could be changed.

As shown in Figure 5, the wedge 13 in the wedge balancing controls is the single wedge of wide-angle monoblock type, and this is simple in structure, and wedge processing and precision are easy to guarantee.And the wedge balancing controls are made up of step pad and wedge two parts in the prior art, and step pad and wedge adopt and divide body structure, and processing and assembling are complicated, and precision can't guarantee,

The backing roll lubricating system changes thin oil circulating lubricating into by the oil-air lubrication before not improving, fast mill bearing when work can produce very big heat, oil-air lubrication can't all be taken away the heat that bearing produces, after time is long, bearing running hot is to significantly reducing the service life of bearing self, bearing deformation has certain increase, and the soleplate shape of band is had very big influence.

Advantage of the present invention and effect be, milling train adopts the complete hydraulic pressing structure, and the AGC cylinder is installed in the milling train top rail Back section, the overall structure of milling train and arrangement form are suitable at a high speed, hightension band rolling, this six roller Milling train is according to the width with steel, and the axial location of mobile intermediate calender rolls is adjusted contact length between the roll with this, To eliminate harmful contact, reduce the elastic deflection of working roll, to improve the control ability of composite plate shape, in order pursuing Higher plate shape control ability, it is poor with plate to reduce, and designs six-high cluster mill of new generation, this six-high cluster mill be Additional middle roll bend in the milling train, thus, work roll diameter can littleizationr, makes rolling thinner, harder The wide plate material becomes possibility, and this is that China's self design first set has the large-scale by six of international most advanced level Cold mill.
