[0002]
[Prior art]
It is important that the grain-oriented silicon steel sheet not only has excellent magnetic properties but also has a good forsterite (Mg ₂ SiO ₄ ) coating. In the production of a grain-oriented silicon steel sheet, a slab for a grain-oriented silicon steel sheet is heated to, for example, 1300 to 1400 ° C to completely dissolve the components Al, N, Mn, and S that form the inhibitor, and form a hot-rolled sheet. Alternatively, annealing is performed to finely precipitate the inhibitor on the intermediate cold-rolled sheet, and after one cold rolling or two or more cold rollings with the intermediate annealing inserted, removal of C, primary recrystallization, and Generally, so-called decarburization annealing is performed for the purpose of forming an oxide layer containing SiO ₂ . Next, after applying an annealing separator mainly composed of MgO to the steel strip, secondary recrystallization, removal of impurities, and finish annealing for the purpose of forming a forsterite film are performed.
[0003]
FIG. 5 is a schematic isometric view of a typical prior art continuous heat treatment facility for decarburizing annealing (including the application of an annealing separator) of a cold rolled sheet of oriented silicon steel, and FIG. FIG. 6 shows an isometric view of the details from the drying furnace exit side to the winding machine (tension reel) in FIG. The furnace section 7 generally includes a heating area, a soaking area, and a cooling area, and the annealing separating agent application device 9 includes a coater, a coating liquid circulation device, a coating liquid preparation device, and the like. The device 11 includes a heating region, a soaking region, and a cooling region, but the description thereof is omitted here.
[0004]
The main elements of such a continuous processing equipment for directional silicon steel strip are a rewinding machine 1 for loading a coiled steel strip of cold-rolled directional silicon steel and unwinding it from there. 2. Incoming shearing machine 3 for cutting and welding the leading end of the steel strip, welding machine 4 for continuously joining the leading end of the steel strip, welding preparation for coil and during welding The inlet side cleaning looper 5 for storing the steel strip for reducing the passing speed in the inlet side cleaning device 6 and the furnace section 7 or enabling the passing without stopping the passing of the sheet, cleaning the surface of the steel strip, The apparatus comprises an inlet-side cleaning device 6 for removing dirt such as rolling oil and iron, and a furnace section 7 having a heating, soaking, and cooling area used for decarburizing and annealing a steel strip.
[0005]
When the winding of the coil is completed and the output shearing machine 13 is operating, the coil can be passed through the outlet side of the furnace unit 7 without decelerating and stopping the inlet side cleaning device 6 and the furnace unit 7. Storage looper 8 for storing a steel strip to be coated, and a coater roll 10 for applying a slurry-like annealing separating agent containing MgO as a main component to the surface of the decarburized annealed steel strip coming out of the furnace part 7. , A device for drying the slurry-like annealing separator applied to the surface of the steel strip, dividing the steel strip according to the unit of winding the steel strip by a winder, and cutting a necessary sample. And a winder 14, 15 for winding the steel strip into a coil.
[0006]
The tension of the steel strip 60 before and after the furnace unit 7 is measured by the tension meters 41 and 42, and the tension of the steel strip 60 in the drying device 11 is measured by the tension meter 43 and the bridle rolls 21a, 21b, and 22a passing therethrough. , 22b, 23a, 23b, 24a, 24b, 24c, 24d, so that the tension of the steel strip before and after the bridle is secured.
[0007]
Since the steel strip to which the slurry-like annealing separator has been applied by the annealing separator applying device 9 is not allowed to come into contact with a roll or the like until the annealing separator is completely dried, the steel strip is passed through the drying furnace 11 to the support roll 36 until the catenary. Or "catenary passing plate (first half) + floating passing plate (second half)", is conveyed without contacting the rolls, and is rewound on winders 14, 15 via deflector pinch rolls 32, 33. Is done. At this time, while the steel strip edge position sensor 51 monitors the steel strip edge position, the winding machines 14 and 15 are shifted by the sheet width direction moving mechanisms 52 and 53 in preparation for the finish annealing in the next step. The steel strip edges on the lower side during finish annealing are aligned. At this time, the upper rolls of the pinch roll 31 and the deflector pinch rolls 32 and 33 are opened (upward standby), and the contact with the steel strip is minimized (not in contact with the pinch roll 31).
[0008]
Note that the annealing separating agent easily peels off when it comes into contact with a roll or the like even after drying, causing a fatal trouble of seizure during finish annealing. Therefore, after contacting the support roll 36, the winding separators 14 and 15 are re-wound. The roll before putting on is set to the minimum necessary.
[0009]
When the exit side steel strip reaches a predetermined weight (generally, a coil unit loaded on the rewinding machine 1 or 2), the steel strip passing through the annealing separator coating device 9 and the drying device 11 is passed. The speed (hereinafter, referred to as the steel sheet exit side passing speed) is reduced, the upper rolls of the pinch roll 31, the deflector pinch rolls 32 and 33 are lowered, and the steel strip is pinched. Split. At the same time, necessary samples are cut and collected.
[0010]
Now, assuming that the preceding steel strip upstream of the split point is being re-wound by the winder 14, when rewinding is completed, the succeeding steel strip downstream of the split point proceeds straight through the deflector pinch roll 32. Then, rewinding is resumed by the winder 33 via the deflector pinch roll 33. When the succeeding steel strip is wound around the winder 15 and the tension is established, the passing speed of the exit side steel strip is increased to the exit side storage looper recovery speed, and the pinch roll 31 and the deflector pinch rolls 32 and 33 are raised. The roll is released (raised) and rewinding continues. When the outlet storage looper 8 recovers the predetermined storage amount, the steel strip passing speed is reduced and synchronized with the furnace section passing speed. The same applies to switching from the winder 15 to the winder 14 (for example, see Patent Document 1).
[0011]
By the way, in the continuous processing equipment for the metal band as described above, the conventional technology for performing edge winding of the tail end of the metal band after the winding tension during steady operation has been eliminated by shearing during winding is continuous. A roll stand having at least a pair of rolls provided in close proximity to a steel strip winder, a steel strip edge detector for detecting an edge portion of the continuous steel strip, and a detection signal of the steel strip edge detector. There is an invention of a meandering correction device for a continuous steel strip, comprising a roll stand position control device for inclining the roll stand with respect to the traveling direction of the continuous steel strip (for example, see Patent Document 2).
[0012]
Further, in order to switch the leading coil and the succeeding coil of the metal strip in a short time, a conventional technique suitable for securing a stable winding condition by switching the winding position and the unloading position of the coil whose winding has been completed. There is a carousel-type continuous winding device in which a plurality of winding reels are arranged on a circular support frame rotatably provided in a vertical plane (for example, see Patent Document 3).

[Problems to be solved by the invention]
However, the above prior art has several disadvantages.
First, the tension of the metal strip changes greatly depending on the following conditions.
(1) When the tip of the metal band starts to be wound around the winders 14 and 15 and when the tension is established,
(2) When the thickness of the metal strip to be processed changes As a result, the parallelism between the axes of the deflector pinch rolls 32 and 33 and the axes of the winders 14 and 15 changes. Even if the winding machines 14 and 15 are shifted by the sheet width direction moving mechanisms 52 and 53 while monitoring the metal band edge position, it becomes difficult to align the lower metal band edge during the finish annealing. .
[0015]
Second, when the coil gradually increases due to the progress of the rewinding of the metal band, the shafts of the winders 14 and 15 bend due to the weight of the wound metal band and the deflector pinch roll 32 of the metal band. , 33, the deformation of the deflector pinch rolls 32, 33 also increases, and consequently, in this case, the parallelism between the axes of the deflector pinch rolls 32, 33 and the axes of the winders 14, 15 is also increased. Is changed, and while monitoring the metal band edge position with the metal band edge position detection sensor 51, the winding machines 14, 15 are shifted by the plate width direction moving mechanisms 52, 53 accordingly, but the lower side during the finish annealing It is difficult to align the edges of the metal band on the side located at. In order to suppress this, an outer board is often installed on the winder, but the deflection of the deflector pinch rolls 32, 33 cannot be solved, and irregularities of the metal band edges still occur frequently.
[0016]
Thirdly, in recent years, in the production of directional silicon steel sheet having a small thickness, a carousel method is sometimes used for a winder from the viewpoint of suppressing a change in the exit side speed when the winder is switched. The parallelism between the axis of the winder and the axis of the deflector pinch roll changes during the Carrozel revolution, which is a major problem.
[0017]
As a measure to make the axis of the winder and the axis of the deflector pinch roll more parallel, Patent Literature 2 discloses a method of inclining a roll stand with respect to a traveling direction of a continuous steel strip.
However, in this method, the traveling direction of the core of the roll of the roll stand and the steel plate is displaced from the vertical direction, and the edge portion of the continuous steel strip detected by the steel strip edge detector which should be originally in a constant relationship. The displacement amount and the shift amount of the winding machine fluctuated, and it was difficult to rewind the winding machine with high accuracy in the width direction.
In general, the distance between the roll stand and the winder is short, and unless it is displaced with extremely high precision, a trouble such as drawing occurs in the steel plate between the roll stand and the winder, and it is difficult to use the steel plate. In particular, with a thin steel plate, this problem is conspicuous, and its application has been practically difficult.
[0018]
In addition, such a deviation in the parallelism between the axis of the winder and the axis of the deflector pinch roll results in a more remarkable irregularity of the metal band edge when the coefficient of friction between the deflector pinch roll and the metal band surface is small.
Further, when a catenary mechanism and / or a floating mechanism is provided upstream of the deflector pinch roll, a more serious problem occurs.
[0019]
As described above, in the metal band processing equipment, the slurry mainly composed of MgO is applied and dried on the metal band, particularly on the surface of the metal band, so that the friction coefficient of the surface of the metal band is small, and in addition, upstream of the deflector pinch roll. It has been difficult to rewind a metal band of directional silicon steel having a catenary mechanism and / or a levitation mechanism over the entire length of the metal band with high precision in the width direction.
[0020]
The present invention, in a continuous processing apparatus for metal strips, advantageously solves the above-mentioned problems of the prior art, and enables winding with high precision in the width direction over the entire length of the metal strip, a meandering correction winding method for the metal strip, and An object of the present invention is to provide a meandering correction winding device for a metal band.
[0021]

[0026]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail.
FIG. 1 is a quasi-schematic isometric view of a continuous heat treatment facility for decarburizing annealing (including the application of an annealing separating agent) of a cold rolled sheet of oriented silicon steel according to one embodiment of the present invention. FIG. 2 shows an isometric view of the details from the drying oven outlet side of FIG. 1 to the tension reel of the carousel winder.
[0027]
5 and 6 except that deflector pinch roll tilting mechanisms 55 and 56 are attached to the output side deflector pinch rolls 32 and 33, respectively. The deflector pinch roll tilting mechanisms 55 and 56 are installed on the side opposite to the drive shaft of the processing equipment, and are mechanisms for raising and lowering the deflector pinch rolls 55 and 56 on the side opposite to the drive shaft.
The other parts of the lines shown in FIGS. 1 and 2 are similar to the lines in FIGS. 5 and 6, and the same parts or devices are denoted by the same reference numerals.
[0028]
Since the steel strip to which the slurry-like annealing separator has been applied by the annealing separator applying device 9 is not allowed to come into contact with a roll or the like until the annealing separator is completely dried, the steel strip is passed through the drying furnace 11 to the support roll 36 until the catenary. Or through the catenary passing board (first half) + floating passing board (second half) without being in contact with the rolls, and then re-wound to the winding machines 14 and 15 via the deflector pinch rolls 32 and 33. Is done.
[0029]
At this time, the deflector pinch rolls 32 and 33 are rotated by the tension indicator value of the tension meter 43 and the weight of the steel strip coil re-wound on the tension reel. The steel strip edge position is monitored by the steel strip edge position detection sensor 51 in preparation for the next step of finishing annealing while maintaining the parallelism between the two, while tilting according to the prediction of the deviation of the parallelism with the 15 axes. Meanwhile, the winding machines 14 and 15 are shifted by the sheet width direction moving mechanisms 52 and 53 in accordance therewith so that the lower steel strip edges are aligned during the finish annealing. At this time, the upper rolls of the pinch roll 31 and the deflector pinch rolls 32 and 33 are opened (upward standby), and the contact with the steel strip is minimized (not in contact with the pinch roll 31).
[0030]
When the exit side steel strip reaches a predetermined weight (generally, a unit of a steel strip coil loaded on the rewinding machine 1 or 2), the steel strip exit side passing speed is reduced, and the pinch roll 31, the deflector After lowering the upper rolls of the pinch rolls 32 and 33 to pinch the steel strip, the steel strip is split by the output shearing machine 13. At the same time, necessary samples are cut and collected.
[0031]
Now, assuming that the preceding steel strip upstream of the split point is being re-wound by the winder 14, when rewinding is completed, the succeeding steel strip downstream of the split point proceeds straight through the deflector pinch roll 32. Then, rewinding to the winder 15 via the deflector pinch roll 33 is restarted. At this time, the steel strip tension is generally zero or a low value, and the deflector pinch roll 33 tilts in accordance with this tension value, and the axis of the deflector pinch roll 33 and the axis of the winder 15 are displaced. Parallelism is maintained (generally the deflector pinch roll is horizontal).
[0032]
When the succeeding steel strip is wound around the winder and establishes tension, the deflector pinch roll 33 is tilted according to the tension, and the parallelism between the axis of the deflector pinch roll 33 and the axis of the winder 15 is adjusted. While maintaining the speed, the passing speed of the exit side metal band is increased to the exit side storage looper recovery speed, the upper rolls of the pinch roll 31, the deflector pinch rolls 32, 33 are opened (raised), and the rewinding is continued. . When the outlet storage looper 8 recovers the predetermined storage amount, the steel strip passing speed is reduced and synchronized with the furnace section passing speed. Switching from the winder 15 to the winder 14 is the same.
[0033]
Although the pinch roll of the deflector pinch roll is not always necessary, it is desirable to install the pinch roll because it facilitates the leading end of the metal band and facilitates the alignment of the metal band edge at the tail end.
The means for detecting the degree of parallelism between the axis of the deflector pinch roll and the axis of the winder is not particularly limited, but a laser system is generally used.
[0034]
Also, it is not always necessary to measure in real time. As in the above example, the tension of the metal band or the weight (coil diameter) of the metal band coil re-wound on the winder and the axis of the deflector pinch roll are used. It is also possible to investigate the relationship between the degree of parallelism and the axis of the winder, and use this result.
Alternatively, the shift amount of the metal strip in the strip width direction under a constant passing condition is determined in advance, and the difference between the actual metal strip edge position detection sensor value and the axis of the deflector pinch roll and the axis of the winder are determined in parallel. It is also effective to regard the deviation as a degree and tilt the deflector pinch roll accordingly.
[0035]
FIG. 3 is a schematic isometric view of a continuous heat treatment facility for decarburizing annealing (including applying an annealing separating agent) of a cold rolled sheet of directional silicon steel, which is another embodiment of the present invention. FIG. 4 and FIG. 4 show an isometric view of details from the drying oven exit side of FIG. 3 to the carousel winder.
1 and 2 except that the winder is a carousel-type winder 17, the output shear is a discharge shear while running 16, and the output storage looper 8 ′ is short. It is.
The other parts of the lines shown in FIGS. 3 and 4 are similar to the lines of FIGS. 1 and 2, and the same parts or devices are denoted by the same reference numerals.
[0036]
When the exit side steel strip reaches a predetermined weight (generally, a unit of a steel strip coil loaded on the rewinding machine 1 or 2), the exit side steel strip passing speed is reduced without decreasing. After lowering the upper roll of the roll 31 and raising the lower roll of the deflector pinch roll 34 to pinch the steel strip, the steel strip is split by the output side traveling shearing machine 16. At the same time, necessary samples are cut and collected. Now, assuming that the preceding steel strip upstream of the split point is being re-wound on the reel 19 located at the strip coil unloading position B, when the re-winding is completed, the succeeding steel strip downstream of the split point becomes Then, the rewinding to the reel 18 located at the steel strip winding start position A via the deflector pinch roll 34 is restarted.
[0037]
At this time, the steel strip tension is generally zero or a low value, and the deflector pinch roll 34 tilts in accordance with this tension value, and the parallelism between the deflector pinch roll 34 and the axis of the reel 18 is maintained. (In general, the deflector pinch roll is horizontal). When the succeeding steel strip is re-wound on the reel 18 to establish tension, the deflector pinch roll 34 is tilted in accordance with the tension, and while maintaining the parallelism between the axis of the deflector pinch roll 34 and the axis of the reel 18, The upper roll of the pinch roll 31 and the lower roll of the deflector pinch roll 34 are released (the pinch roll is raised and the deflector roll is lowered), and rewinding is continued.
[0038]
At the time when the steel strip coil is carried out of the line from the reel 19 located at the steel strip coil unloading position B, the carousel winder 17 tilts the deflector pinch roll 34 while running the steel strip, and deflector pinch roll While maintaining the parallelism of the axis of the reel and the axis of the reel, the carousel reel revolving mechanism 20 revolves, the reel 18 moves to the steel strip coil unloading position B, and the reel 19 moves to the steel strip winding start position A, Rewinding is continued at the steel strip coil unloading position B. At this time, the reason why the deflector pinch roll 34 is tilted is that the parallelism of the axis of the reel 19 changes with the axis of the deflector pinch roll due to the revolution of the carousel.
The same applies to the switching from the reel 19 to the reel 18.
In this manner, even in the case of the carousel type winder, the edges of the steel strip can be aligned very finely on the lower side during the finish annealing over the entire length of the steel strip including the revolution.
[0039]
The present invention is also effective for an annealing furnace and an annealing method for performing nitriding annealing after decarburizing annealing of a silicon steel sheet.
Further, the present invention is not only effective for an annealing furnace for silicon steel sheets, but also has a catenary mechanism and / or a floating mechanism upstream of a deflector pinch roll, and / or a continuous processing equipment for a metal band having a low coefficient of friction. It is also effective for winding a metal band in a continuous metal band processing facility.
[0040]
【The invention's effect】
As described above in detail, according to the present invention, in the continuous processing equipment for metal strips, the deflector pinch roll immediately before the winder is provided with a tilting function, and the amount of meandering (shift) in the width direction of the metal strips is adjusted. By shifting the winder in the width direction and tilting the deflector pinch roll, the edges of the metal band re-wound on the winder can be aligned very accurately over the entire length of the metal band. it can. In particular, the effect is enormous in a metal band of directional silicon steel coated with an annealing separator and dried.
