Description
Technical field
The present invention relates to cold rolling steel rolling field, more particularly, to a kind of strip steel automatic correction method and device.
Background technology
When producing, often there is deviation phenomenon in strip steel to tandem mills, can wipe the equipment of touching when sideslip is serious, causes device damage, and strip steel tears.The reason sideslip have multiple such as：Step rate Disalignment, on dolly, volume centrage is inclined, strip steel shape wave, camber etc., after the strip steel of sideslip reaches welding machine, weld seam dislocation, strip steel distortion can be caused to form camber, this defect all adversely affects to later process disk sheared edge and mill milling, have a strong impact on unit normally to produce, therefore strip steel has to carry out correction process when running on unit operation line.
Currently for the phenomenon of uncoiler strip running deviation, typically adopt two kinds of correcting methods：One be using flipper guide, coils of hot-rolled steel is taken the lead, tail is corrected, but this method centering capacity is extremely limited, strip steel sideslip end to end by a small margin can only be corrected, because the width range of flipper guide is more somewhat larger than the width of strip steel, when strip running deviation amplitude is very big, the setting width that strip steel will exceed flipper guide because of width cannot be introduced into flipper guide region, breaks flipper guide or strip steel self-deformation.Two is artificial crawl reel of uncoiler play, find that the position of coil of strip corrected by strip running deviation play uncoiler, this mode is fuzzyyer to the control ratio of position, because not knowing the running deviation value of strip steel, it is poor to be that feel by operative employee is controlled effectiveness comparison, if roller system is affected uneven wear by strip running deviation for a long time, the sideslip that can aggravate strip steel has a strong impact on the normal operation of production；Separately have a kind of in the form of traditional correction grating+deviation rectification roller, need unit is largely transformed, also will depend on and whether have enough spaces to carry out such transformation, be largely limited by the structure arrangement condition of unit.
A kind of photo-electric deviation rectifying system for decoiler is disclosed in prior art Chinese patent CN200920076753.5, mainly by hydraulic cylinder, servo proportion, high frequency photodetector system, PLC controller, magnetostriction position sensor, hydraulic test etc. form the 4 rollers thick intermediate mill uncoiling CPC system that this system is manufactured by western weight institute autonomous Design.It is a kind of closed-loop electrohydraulic servo-controlling system.CPC control function is completed by PLC.Its major control principle is that the oil cylinder position feedback signal of the detection signal of strip location and uncoiler is delivered to PLC, and after carrying out PID computing, output signal controls uncoiler support oil cylinder proportional servo valve, makes double capital uncoiler movement to control centre position of strip；Although this system overcomes the inaccurate defect in artificial crawl uncoiler position; but this system may be only available for not having coil of strip outer ring could normally use in the case of overflowing; and install photo-electric detecting system below large-scale uncoiler; installation to fragile fluorescent tube system equipment and protective measure are big difficult points, and the motility of system equipment, practicality are all poor.
Content of the invention
