Description of the Related Art Currently, nonwoven fabric squeezing rolls are used for squeezing a liquid used in a washing process performed near a final process such as a metal cold rolling line, but nonwoven fabric squeezed rolls produced in a factory are used. If the roll is used as it is for the squeezing of the washing liquid used in the washing process of the cold rolled steel sheet, a large amount of unsqueezed residue will be left out, so that it is not very usable in an actual production line. Therefore, prior to use, for example, the surface of a new nonwoven fabric drawing roll is ground in advance by a method of grinding with a cutting tool disclosed in Japanese Unexamined Patent Publication No. 63-99101 so that predetermined characteristics are obtained, and further, the fabric is conditioned for a certain period of time. At present, they are used (empty use) and then used in actual manufacturing processes such as metal cold rolling lines. Squeezing of the liquid after washing without breaking in the nonwoven fabric squeezing roll immediately after grinding by the above method, for example, a pattern may be formed on the surface of the cold-rolled steel sheet when used for squeezing the cleaning liquid of the cold-rolled steel sheet. Alternatively, there is a problem that inconvenience such as generation of unevenness on the surface occurs. The cause of the failure to achieve the predetermined drawing performance even after grinding is not apparent before the completion of the present invention, and therefore, it is used until the predetermined drawing performance is achieved. At present, it is used for actual drawing work. For this reason, in a line such as a metal cold-rolling line, which requires the squeezing operation of a cleaning liquid, the break-in use of a spare non-woven fabric squeezing roll must be constantly performed systematically, and the cost incurred for that purpose is ridiculous. There is a problem that it does not become.

特徴とする金属条の製造方法が提供される。Means for Solving the Problems The present invention has been made to solve the above-mentioned problems, and after manufacturing a nonwoven fabric squeezed roll by a conventional method, the polishing process is performed on the roll through a polishing process under specific conditions. By controlling the surface roughness within a specific range, the present inventors have found that the present invention can be used for liquid squeezing work immediately after production, and have completed the present invention. That is, when the drawing performance immediately after the production of the nonwoven fabric drawing roll (hereinafter referred to as initial drawing performance) was variously examined in relation to the state of the surface of the nonwoven fabric drawing roll, the surface roughness Ra of the roll was 0.1 μm to 2. By setting the surface roughness within a range of 5 μm and a maximum surface roughness Rmax (hereinafter sometimes simply referred to as Rmax) within a range of 1 to 20 μm, the initial drawing performance satisfies a required level as a predetermined drawing performance. And completed the invention of the present application. In order to form a surface that satisfies the above surface roughness, the nonwoven fabric squeezing roll, which is the material to be polished, is rotated at a remarkably high speed as compared with the abrasive, and the particle size of the applied abrasive is from # 1500 to # 3000. The present inventors have found that it is essential to use the present invention and have arrived at the present invention.
More specifically, the surface roughness Ra is set to 0.1 μm as described above.
m to 2.5 μm, and Rmax is 1 to 20.
In order to make the thickness within the range of μm, the nonwoven fabric squeezing roll manufactured by a conventional method is rotated at a peripheral speed of 50 rpm to 200 rpm, and the pressing pressure is 3 kg / 100 mm to 20 kg /.
The particle size is from # 1500 to # 300 on the same roll at 100mm
Pressing the applied abrasive at 0 mm and rotating the abrasive very slowly, the polishing head is moved from 30 mm / min to 200 mm.
It has been found that the above-mentioned object is achieved by moving on the roll in the longitudinal direction of the roll at a speed of / min. That is, according to the present invention, the surface roughness Ra immediately after polishing is in the range of 0.1 μm to 2.5 μm, and Rmax is 1 to 20 μm. A polishing method is provided. Furthermore, there is provided a method for producing a metal strip, characterized by using the thus produced nonwoven fabric drawing roll in a drawing step of a metal cold rolling line.

いる方法で製造することが出来る。BEST MODE FOR CARRYING OUT THE INVENTION The nonwoven fabric roll according to the present invention comprises:
A synthetic resin fiber having a diameter of 3 to 20 denier (10 to 60 μm), a natural fiber, or a mixture thereof is mixed with a suitable binder, and the mixture is used by an air lay method, a card method, a spun bond method, or the like. Porosity of 10
From 60% non-woven fabric squeezing roll, and polishing it under the specific conditions as described above. Examples of synthetic resin fibers that can be used include polyamide-based fibers, polyether-based fibers, and polyolefin-based fibers. Above all, fibers made of polyethylene or nylon can be more preferably used in terms of polishing performance and chemical resistance to chemicals such as cutting oil used for cleaning. Natural fibers that can be used include cotton and those made from hemp. The fibers used in the production of the nonwoven squeezing roll include those having a diameter of 3 to 20 denier. If the diameter is less than 3 denier, it takes not only a long time to polish the surface of the manufactured nonwoven fabric squeezing roll to a desired range, but also a problem that abrasion of the applied abrasive material may occur, 20 diameter
If the denier is exceeded, fluffing during polishing increases, and the roll surface cannot be polished within a desired range. When the fiber diameter is in the range of 6 denier to 15 denier, it is more preferable in view of workability of polishing.
Examples of the binder used for forming the nonwoven fabric squeezing roll include acrylic binders and alkylbenzene sulfonate binders. There is no particular limitation on the method of forming the non-woven fabric drawing roll, but usually, the above-described air-lay method, card method, or spun-bond method may be employed. More specifically, the nonwoven fabric squeezing roll usable for the method of polishing the surface of the nonwoven fabric squeezing roll according to the present invention may be any of a spiral type, a disk lamination type, a flap type, and the like. Is well known. That is, these nonwoven fabric squeezing rolls can be manufactured by the method disclosed in, for example, International Publication WO97 / 27029.

0%, more preferably in the range of 20 to 40%. If the porosity is less than 10%, the hardness of the roll becomes too hard and cannot be used for drawing, and if the porosity exceeds 60%, the hardness becomes too soft and the strength of the member is greatly increased. It is not preferable because the durability is lost, for example, it is consumed in a short time due to the decrease. The porosity is preferably 20 to 40% in view of the difficulty of the drawing operation and the drawing efficiency. Of course, depending on the conditions of the squeezing work,
Needless to say, a nonwoven fabric roll in a range other than 20 to 40% may be suitably used. The size of the nonwoven fabric squeezing roll may be selected according to the purpose of use. The size of a typical nonwoven fabric squeezing roll has an outer diameter of 100 to 500 mm and an inner diameter of 50 to 30.

させることが好ましい。The conditions of the polishing step for the surface of the nonwoven fabric squeezing roll, which is one of the most important processes in the production of the nonwoven fabric squeezing roll according to the present invention, are as follows. In the polishing method according to the present invention, for example, when a polishing apparatus having a configuration schematically shown in FIG. 1 is used, after a nonwoven fabric squeezing roll is mounted on the polishing apparatus, the peripheral speed is 50 to 200.
rpm, preferably at least 100 rpm, while simultaneously pressing the coated abrasive with
While pressing against a non-woven fabric roll with a force of kg / 100 mm to 20 kg / 100 mm, a polishing head having a predetermined width, for example, a width of 1/2 to 1/2 of the width of the non-woven fabric drawing roll, is moved in the longitudinal direction of the non-woven fabric drawing roll. 30mm / min ~ 8
While moving at a speed of 0 mm / min, the coated abrasive is moved at a very slow speed, for example, from 15 mm / min to 60 mm.
/ Minute. In polishing, there are dry polishing without adding water and wet polishing using water.In the polishing of the nonwoven fabric squeezing roll according to the present invention, in the case of wet polishing, the nonwoven fabric squeezing roll swells and is polished. Dry polishing is preferred because of the drawback of reduced efficiency. Of course, depending on the configuration of the polishing apparatus, desired effects may be produced outside the above range. However, these ranges are modifications within a range obvious to those skilled in the art, and are naturally of the present invention. It goes without saying that it is within the range. When the feed speed of the nonwoven fabric roll is less than 50 rpm, the working efficiency is usually poor, and the peripheral speed is 200 rpm, although it depends on the outer diameter of the nonwoven fabric roll.
When dry polishing is performed, baking tends to occur on the roll surface in dry polishing. During polishing, pressing the applied abrasive to the nonwoven fabric squeezing roll with a force within the above range is preferable in order to avoid inconveniences such as a non-uniformity in the surface roughness of the nonwoven squeezed roll after polishing. Because. The polishing head is usually moved at a speed within the above range at a speed of 30 to 80 mm / min in the longitudinal direction of the nonwoven fabric squeezing roll, although it may vary depending on the size of the applied abrasive. If the moving speed is too high, the polishing becomes insufficient, which is not preferable. The applied abrasive need not be rotated in effect. However, since the surface of the applied abrasive may be clogged, it is preferable to move the abrasive slowly at least at the above speed.

と同様である。As the applied abrasive used in the polishing method of the present invention, an applied abrasive having a particle size of # 1500 to # 3000, particularly abrasive paper, is suitably used. # 1500
In the case of a coarser abrasive, the Rmax becomes 30 μm or more, and the nonwoven squeezing roll after polishing cannot be used as it is in the squeezing step. Also, if an abrasive having a finer particle size than # 3000 is used, a surface roughness within a desired range can be produced, but the moving speed of the polishing head must be remarkably slowed down. However, it is not preferable because the consumption of the abrasive is also increased. By adjusting the particle size of the applied abrasive and the rotation speed of the nonwoven cloth squeezing roll, a nonwoven cloth squeezing roll having a desired surface roughness that meets the requirements of the squeezing operation can be obtained. Needless to say, the polishing method according to the present invention can also be used for regenerating the roughness of the surface of the nonwoven fabric drawing roll, which has failed to exhibit the desired performance while being used in the drawing process. Furthermore, if the nonwoven fabric squeezing roll whose surface roughness according to the present invention is controlled within a specific range is used for squeezing of a cleaning liquid such as a metal cold rolling line, a metal cold rolled strip having a desired surface state can be obtained. Is easily manufactured. As the cleaning liquid used in the cleaning step, water, mineral oil such as cutting oil, and organic chemicals such as trifluoroethylene are used. The nonwoven fabric squeezing roll according to the invention is suitably used. Even when the drawing work is performed using the nonwoven fabric drawing roll according to the present invention, the working conditions are the same as those of the conventional nonwoven fabric drawing roll.

A non-woven fabric drawing roll having a of 2.5 μm and an Rmax of 20 μm was mounted on a drawing machine in a drawing operation after a washing step with water in a metal cold rolling line, and the drawing operation was performed under a pressure of 20 kg / cm 2 . After the squeezing operation was completed, the residual water amount on the metal surface was measured using the apparatus schematically shown in FIG. 2 in the following manner, and the residual water amount was below 0.3 g / m 2 , which is the standard for the residual water amount required in this step. A very satisfactory drawing operation of 0.23 g / m 2 could be performed. 1. The iron roll is rotated at a peripheral speed of 100 m / min, and water is carried by the roll. 2. A non-woven fabric drawing roll is pressed with a linear pressure of 15 kg / cm. 3. A filter paper (20 mm × 60 mm) is pressed against the iron roll on the open side with a force of 2 kg for about 10 seconds, water remaining on the iron roll is forcibly absorbed by the filter paper, and the weight of the filter paper is measured. . 4. Calculate the roll passage area from the peripheral speed of the iron roll,
The remaining water amount per square meter is calculated from the remaining water amount obtained in the above 3. It should be noted that the same effect was obtained when used in the squeezing work after the washing step with the cutting oil instead of the water washing. Incidentally, the same lot as the unpolished non-woven squeezed roll used in the above production example, the surface of which was ground by the grinding method disclosed in JP-A-63-99101, was directly used in the squeezing step under the same conditions as above. When the residual water amount after squeezing was measured, it was found to be extremely high at 1.7 g / m 2, and it was found that the residual water amount could not withstand actual use. Further, when the fabric was used for about 45 days under the same conditions as in the actual drawing process, the remaining water amount was 0.25 g / m 2 , which is almost the same as the nonwoven fabric drawing roll according to the present invention for the first time. As is clear from the above results, it can be seen that the nonwoven fabric drawing roll according to the present invention can be used for actual drawing work immediately after production without using so-called break-in.

来るという効果が得られる。As described above, the non-woven fabric drawing roll according to the present invention can be used in the actual drawing process even in a state immediately after polishing. Therefore, after processing the surface like a conventional non-woven fabric drawing roll, Furthermore, since it is not necessary to perform so-called "break-in use" for a long period of time, it is possible to eliminate the waste of preparing a spare non-woven fabric squeezing roll in advance and running it. In that regard, in the case of the nonwoven fabric drawing roll according to the present invention which does not require any break-in use, in the case of various users performing a drawing process such as a metal cold rolling line where the use of the nonwoven fabric drawing roll is indispensable, the present invention By using the nonwoven fabric squeezing roll according to the present invention, there is obtained an effect that various economical burdens caused by so-called break-in can be reduced. Further, according to the method for producing a nonwoven fabric squeezing roll which does not require so-called break-in use according to the present invention, the nonwoven fabric squeezing roll can be polished intentionally and / or without requiring a long time. In a state where there is no spare non-woven squeezing roll available, even if an unexpected situation occurs in the non-woven squeezing roll in use, it is possible to solve the problem that the squeezing process must be stopped for a long period of time. Further, by using the nonwoven fabric squeezing roll according to the present invention for the squeezing operation of the cleaning liquid in the gold cold rolling line, an effect that a metal strip having a desired surface condition can be produced can be obtained.
