Background technology
The rolling of steel band can be realized at dissimilar rolling equipments.So-called " reversible " rolling equipment allows alternately then to come the rolling band that moves along rolling direction along another direction along a direction.Band is rolling by passing milling train, and wherein said milling train comprises a frame or two frames along the rolling direction arranged in succession between two coiling/take-off devices.
Than " single chassis " but 200000 to 600000 tons the production capacity in every year of reverse means, but the Stand Mill reverse means has annual 300000 to 1000000 tons production capacity.But the Stand Mill reverse means also has and reduces along a direction then along the advantage of the rolling road number of times of another direction.Patent EP0 618 018 B1 have described a kind of so cold rolling Stand Mill reversible rolling equipment of permission.
In the situation by the reversible rolling of implementing above three passages, the head end of band and tail end keep being sandwiched on the axle of the coiling/take-off device that is positioned at the Stand Mill both sides.The active length that is included between clamping place (emprise) of the head end of band on the one hand or tail end and the roll that is positioned near the frame coilings/take-off device on the other hand is not rolled down to the thickness of pursuing, and fixes head end or the tail end of to some extent consideration on wherein said coiling/take-off device.
In addition, when passage finished, length was not rolled down to the thickness of pursuing between the frame between clamping place of the roll of two frames.In fact, length only is being rolled by near one in two frames (namely be located thereon the coiling/take-off device that is fixed with the head end considered or tail end frame) time between this frame.
Therefore, at every end of band, has overproof thickness corresponding to the end length of the summation of length between active length and frame.Two end length must be removed and reclaim (mise aumille) when rolling end.But this recovery has caused the loss of the efficient of Stand Mill reverse means.
For example, for be used for according to three passage rolling widths can reach 1600mm, original depth is that 3mm and length are the milling train of the steel coil strip of 700m, in order to obtain to have the steel band of the 1mm thickness of pursuing, such Stand Mill reversible rolling equipment must be set, and namely its each frame has about 2400 tons rolling power.For this reason, for example to be equipped with diameter be that backing roll and the diameter of 1250mm is the working roll of 450mm to each frame.In order to bear corresponding power, each frame generally has column, and the height of column is 9000mm, and width is 4000mm.The axle base of separating the symmetrical plane of two frames is 6000mm, and wherein said symmetrical plane is that roll axis is positioned at perpendicular wherein.
Therefore, when using this equipment, the amount of the band that loses in active length is 2% of the former roll coil of strip.When the axle base of two frames is 6000mm, be 1% of the former roll coil of strip corresponding to the recovery spacing of length between two frames.Therefore, cause surpassing 3% total losses of the former roll coil of strip.This should with about 2% common loss of singlestandmill, and the insignificant loss of continous way series connection milling train is compared.
Notice that axle base must be greater than the minimum of a value that is determined by the geometrical construction of frame and the restriction of the installation on civil engineering thereof.Especially, according to prior art, the column of the frame of double-stand reversible mill comprises the fixedly ear on the civil engineering.Fixedly ear on the column forms along rolling direction and exceeds the projection of perpendicular that column comprises the face of this ear.Especially, the column of the first frame perpendicular to rolling direction and have an ear that protrudes to the second frame towards the side of the second frame.Symmetrically, the column of the second frame perpendicular to rolling direction and have an ear that protrudes to the first frame towards the side of the first frame.Fixedly ear causes the axle base of 6000mm, namely causes distance between the frame of 2000mm, and distance is positioned at the distance of two lateral surfaces on each columns of the first and second frames, that mutually face toward between this frame corresponding to separation.
Fixedly ear comprises through hole, is used for passing through of the fixture of column on civil engineering.In addition, these fixedly the lower surface of ear consist of the supporting surface of column on civil engineering.As for the lower surface of column, it is lower to extend the fixedly height below of the lower surface of ear, and be located at the below that is disposed in frame in the civil engineering, the top in the hole of the lubricating oil used for access.
Tried hard to reduce the recovery of double-stand reversible mill.For example, patent JP 03-138004 has described and has used the extension element that is welded on each end for the treatment of rolling band, and the particular order of the opening and closing of a kind of frame and anchor clamps, with whole strip-rolling to the thickness of being pursued.
