The rolling of steel band can be realized on dissimilar rolling equipments.So-called " reversible " rolling equipment allows alternately to come the rolling band that moves along rolling direction along another direction then 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 two-shipper frame reverse means has annual 300000 to 1000000 tons production capacity.But two-shipper frame reverse means also have minimizing 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 two-shipper frame reversible rolling equipment of permission.
Under 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 two-shipper frame 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 being pursued, and fixes the head end or the tail end of consideration to some extent on wherein said coiling/take-off device.
In addition, when passage finished, length was not rolled down to the thickness of being pursued between the frame between clamping place of the roll of two frames.In fact, length only is being rolled by one in two frames (near the frame the coiling/take-off device of ascend the throne fixing thereon head end of considering to some extent or tail end) 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 two-shipper frame 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 being pursued, such two-shipper frame reversible rolling equipment must be set, and promptly its each frame all has about 2400 tons rolling power.For this reason, all 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 all 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 on 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.
