Abstract
The invention relates to an anti-tower shaped defect control method for a coiler's asymmetric side guide plate. The method includes: deflecting the transfer rollers of a coiler's transfer roller group, keeping the opening of a driving side guide plate at the level of strip steel width/2 and the opening of a work side guide plate in the range of strip steel width/2+60mm-strip steel width/2+100mm, making a roll table rotate to push the strip steel forward and generate a divergent pushing force simultaneously so as to make the strip steel operate closely to the driving side guide plate, when the strip steel head completely enter the side plates, letting the work side guide plate quickly draw close to the driving side guide plate to realize close, and keeping the driving side guide plate still till the strip steel head is bitten into a subsequent pinch roll group. The method provided by the invention can reduce tower shaped defects of the strip steel, improve coil quality, has no need for recoiling and repair, and saves manpower and material resources. And the method has small investment in equipment hardware transformation, only needs to make angular adjustment on part of the roll table, and other improvements can be achieved by modifying software. Thus, the method is suitable to the field of preventing steel coil tower shaped defects by coilers in various steel production.
Description
Technical field
The control method that the present invention relates to a kind of object operation, relates in particular to a kind of control method that is applied to the asymmetric flipper guide of coiling machine in iron and steel production field, can prevent the turriform defect of coil of strip.
Background technology
At present, on hot rolling line in each steel production enterprise, be widely used a kind of coiling machine, coiling machine is as a kind of visual plant of hot rolling line, and coiling machine is arranged at after mm finishing mill unit, for last procedure of hot continuous rolling production line, the finished product hot-strip of rolling is rolled into coil of strip.Coiling machine under prior art mainly comprises that roller-way, flipper guide, pinch roll, three help the capital equipment such as winding up roller and reel, also comprise some auxiliary taking-up equipments in addition.Wherein roller-way is mainly responsible for band steel to be delivered to coiling machine by mm finishing mill unit, flipper guide Main Function is centering band steel, the Main Function of pinch roll is to sting the steel stage to apply certain clamping force with steel at head, it is implemented to flexural deformation for the first time simultaneously, finally batch the stage to apply stable tension force with steel at afterbody, to ensure good scroll quality, and help some auxiliary taking-up equipments such as winding up roller to help the bending of band steel, and make to be with steel to be tightly wound around coiling, wherein reel is one of nucleus equipment of coiling machine, after band steel is wound around, it is applied to forward direction tension force, up-to-standard to guarantee scroll.
But, produce through long coil of strip, field worker is found, coiling machine under prior art is very easy to produce turriform defect in the curly course of its coil of strip, as shown in Figure 1, turriform defect is exactly that the inner ring volume layer of coil of strip is to the open defect of a side protrusion, protrude and be fore side turriform defect to fore side, protrude and be transmission side turriform defect to transmission side, and user generally has very harsh requirement to inner ring turriform defect, exceed if there is the coil of strip of turriform defect the inner ring turriform that user requires, can only in the time of finishing procedure, carry out rewinding repairing, not only cause like this loss of quality cost, and extremely consume manpower and materials.
Under prior art in order to prevent turriform defect, taked a kind of symmetrical flipper guide control method, as described below:
As shown in Figure 2, flipper guide is made up of transmission side flipper guide and fore side flipper guide, all adopts symmetrical aperture to set, and adopts following methods control:
1. band steel head arrives before flipper guide, and transmission side flipper guide and fore side flipper guide are set in identical aperture symmetrically, i.e. aperture=strip width/the 2+50mm of flipper guide;
2. when band steel head is when the flipper guide, the quick closedown simultaneously of fore side flipper guide and transmission side flipper guide;
3. when band steel afterbody is by after flipper guide, fore side flipper guide and transmission side flipper guide are opened simultaneously.
That is to say under prior art, transmission side flipper guide and fore side flipper guide keep with rolling centerline the distance equating all the time, adopt symmetrical flipper guide control method.
But through execute-in-place workman's long-term use, we find that the symmetrical flipper guide control method under prior art is used for preventing that turriform defect from still existing following problem:
1. arrive before flipper guide at band steel head, the aperture of flipper guide is greater than the width with steel, band steel within the scope of flipper guide aperture in free state.Band steel can move about to any side, while moving about to fore side, has just produced fore side turriform; While moving about to transmission side, just produce transmission side turriform.
2. because the quick closedown of flipper guide needs a period of time, during this period of time, unavoidably to produce certain turriform defect.The time that quick closedown needs is longer, and turriform defect is more serious, but the shut-in time is too short, easily band steel clamp is stopped again.
So the side guide plate of recoiling machine under prior art adopts symmetrical flipper guide control method still cannot meet the quality requirement of coil of strip, still can produce turriform defect.
Summary of the invention
While batching coil of strip in order to solve coiling machine, easily produce turriform defect, and flipper guide under prior art adopts symmetrical flipper guide control method also cannot solve the problem of this defect, the invention provides control method and the application of the anti-turriform defect of the asymmetric flipper guide of a kind of coiling machine, quick closedown process and band steel mainly for flipper guide freely move about within the scope of flipper guide aperture, unavoidably to produce the problem of turriform defect, for the different characteristics of slab and thin plate, by the adjustment of offside guide plate center line, and the roller-way of arranging in conjunction with oblique angle, reach the object that reduces turriform defect, concrete scheme of the present invention is as described below:
A control method for the anti-turriform defect of the asymmetric flipper guide of coiling machine, is characterized in that:
1) 80 ~ 120 transfer roller deflections of the steel of contact zones at first of coiling machine transfer roller group are arranged;
2) described transfer roller deflection arranges that it is specially, to between the axis of every transfer roller and rolling centerline, form a deflection angle by 90 ° of original normal deflections, make coiling machine transfer roller group when rotation promotes to be forward with steel, form towards a side point to thrust, make flipper guide operation that it is adjacent to this side;
The angle of deflection angle is larger, larger towards the thrust of side direction.
3) offside guide plate center line is adjusted as follows:
3.1) transfer roller of the coiling machine transfer roller group of deflection layout roller-way is to transmission side flipper guide deflection;
