低下の原因となる欠点があつた。As such a buff roll for mirror polishing of the surface of a stainless steel strip, conventionally, as shown in the side view of FIG. 3 and the front view of FIG. 4, a woven fabric 1 made of sisal or cotton is bias cut to remove the woven fabric 1 from the woven fabric 1. A large number of buff wheels fixed to the periphery of the metal fitting 6 are positioned on the outer periphery so that the cut edges of the fibers are prevented from falling off and the cut edges form a polished surface, and are assembled into the shaft 5 as shown in FIG. It was generally used that it was fixed by a nut 4 via a roll to form a roll. The buff roll for mirror polishing was formed in pairs with the billy roll 2 and arranged in multiple stages as shown in FIG. 1, for example, and the surface of the stainless steel strip S was mirror-polished. However, if defects on the surface of the stainless steel strip S (such as spot-like patterns) are removed and the rolling force of the mirror polishing buff roll is increased in order to carry out mirror polishing, the friction between the stainless steel strip surface and the mirror polishing baffle is increased. The temperature of the buff material rises due to heat, the buff material deteriorates, and at the same time, the phenomenon of colored "burning" on the surface of the stainless steel strip occurs and the surface quality deteriorates. If the reduction force of the buff roll for mirror polishing is reduced to prevent it, the surface gloss of the stainless steel strip surface and the image definition described below will be reduced, so it is necessary to repeat the polishing of the stainless steel strip surface for 2-3 passes. However, there was a drawback that reduced the efficiency.

たのである。As described above, in the prior art, since the buff material for the mirror-finishing baffle is a woven fabric made of sisal or cotton, surface defects such as spot-like patterns on the surface of the stainless steel strip are removed and the surface gloss and the image clarity are improved. The buff roll for mirror polishing is increased in order to increase the pressure, and the pressing force of this buff fluor for mirror polishing on the stainless steel strip (hereinafter,
Even if you try to increase the buff pressure), it is already close to the limit, so burns that occur on the surface of the steel strip (below,
In order to prevent the occurrence of buff burning), the rolling force of the mirror polishing buff roller could not be increased more than the current level. Therefore, the number of times of polishing the surface of the stainless steel strip was increased, and the polishing had to be carried out a large number of times such as 2 or 3 passes, and the efficiency of mirror polishing of the surface of the stainless steel strip was inevitably reduced.

たのである。The present inventors, as a result of earnest research to solve the above problems,
The buff material does not deteriorate even when the surface temperature of the stainless steel strip reaches 100 ° C or more due to contact with the rotating buff roll for mirror polishing which raises the buff pressure by raising the rolling force of the buff roll for mirror polishing. In order to enable mirror polishing without causing buff burning on the surface of the steel strip, the buff material of the bufflor for mirror polishing is made of viscose rayon filament that has better heat resistance than the conventional woven fabric made of sisal or cotton. The cellulosic fiber is made into a woven fabric and the acrylic or ester aqueous solution is roll-coated and then hardened by permanent pressing, and then cut to a bias to prevent the fibers from falling off due to fraying. Is used to form a polishing surface, and the buff roller for mirror polishing thus constructed is used to meet specific polishing conditions. Than it was investigated to be able to satisfactorily and efficiently mirror-polished by applying a higher buff pressure than conventional one surface of the stainless steel strip when Seshimere operating Te Unishi.

製造出来ること、 というメリツトを有しているからである。In the present invention, as a buffing material for bufflor for mirror-polishing, a viscose rayon filament is selected as a viscose rayon filament, which is different from the conventional natural fiber such as sisal or cotton. Since it is an artificial fiber, there is no difference in quality and an extremely homogeneous material can be obtained, and the fiber cross-sectional structure, which is the peculiarity of viscose rayon, is composed of a relatively hard and durable skin layer and a soft core. This is because the fiber has the merit that the cross-sectional shape of the fiber has a large number of complex irregularities, and that since it is an artificial fiber, the thickness and length of the fiber can be freely manufactured.

る。That is, in the thickness (fineness) of the fiber, the viscose rayon filament as the buff material of the polishing bufflor according to the present invention has a denier of 500 denier or more, about 1000 denier as compared with 1.5 denier of cotton and 4-5 denier of hemp. Since denier is used, it is also excellent in durability and wear resistance in combination with the fiber structure. In natural fibers having a small thickness and a small length of fibers constituting one thread, buffs are often scattered during mirror polishing of a stainless steel strip, but rayon used in the present invention is extremely small. Have advantages.

℃で色分解し始める程度であり、耐熱性の点で優れてい
る。The reason why the use of synthetic fibers was intentionally avoided in the present invention is that synthetic fibers have a uniform structure with no skin layer or core structure in the fiber cross section, and are very strong at room temperature but weak against heat. This is because it is unsuitable for applications where heat is generated during work and the temperature rises, such as a buff roll for mirror polishing.
That is, nylon has 180 ° C, vinyl chloride has 200-210 ° C, acrylic has 190-240 ° C, polyester has 238-240 ° C, polyethylene has 100-115 ° C, and polypropylene has 140-160 ° C. [Note: cotton turns yellow at 120 ° C and 150 ° C
Decompose with. Also, sisal hemp turns yellow at 130 ° C and decomposes at 200 ° C]. In contrast, viscose rayon is 260-300
It begins to undergo color separation at ℃ and is excellent in heat resistance.

目的に合致せしめればよい。In the present invention, as described above, viscose rayon, which is excellent as a buff roll material, is used, and after the fabric made of the fiber is further subjected to a hardening treatment, the fabric is cut into a bias to form a polished surface at the cut edge. The mirror polishing buff roll is constructed as described above. On this occasion,
Considering the degree of mirror polishing and finish, the denier of the thread,
It is sufficient to appropriately adjust the driving density of the woven fabric, the degree of curing processing, etc. to meet the purpose.

である。The reason for limiting the above conditions is that, with respect to the condition a, if the above-mentioned buff roll for mirror polishing is not used, the buff pressure for raising the buff pressure is increased by increasing the rolling force of the buff roll for mirror polishing, and the buff roll for mirror polishing is rotated. This is because the buff material does not change in quality even if the temperature rises to 100 ° C. or more due to the contact with the steel sheet, and mirror surface polishing cannot be performed without causing buff burning on the surface of the stainless steel strip. Regarding the condition b, when the rotating direction of the mirror polishing baffle is reversely rotated with respect to the plate passing direction of the stainless steel strip,
The polishing agent cannot be supplied well to the contact portion between the surface of the stainless steel strip and the surface of the mirror-polishing buffle, which will be described later, and the buff material of the mirror-polishing baffle is severely damaged and its service life is shortened. Therefore, not only is it difficult to remove surface defects such as spots on the surface of the stainless steel strip, and a mirror surface cannot be obtained, but the buff material does not deteriorate even when the buff roll for mirror polishing under the condition a is used and the stainless steel is used. This is because the effect of not causing buff burning on the band surface cannot be exhibited. Then, in order to exert such an effect, the present inventors have determined that the peripheral speed is 1900 to 2500 than the strip running speed.
It was determined that it is preferable that m / min is large. This is preferable because if the speed difference obtained by subtracting the stripping speed from the peripheral speed of the mirror-polishing buffalo is less than 1900 m / min, the polishing of the surface of the stainless steel strip is insufficient and satisfactory mirror-polishing may not be performed. If it exceeds 2500 m / min, the rotation speed of the buff roll for mirror polishing is too fast, the temperature of the buff material rises too much, the useful life of the buff roll for mirror polishing decreases, and buff burning may occur, which is not preferable. Is. Regarding the condition c, the present inventors have already mentioned that the buff material as a buff roller for mirror surface polishing is a mirror surface made of a special material which does not cause buffing and does not cause buff burning on the stainless steel strip surface. when using abrasive for Bafuroru, pressing pressure of the stainless steel strip Bafuroru for mirror polishing is 1~5.6kg / cm 2 higher than the pressing pressure on the stainless steel strip of a conventional Bafuroru for mirror polishing 2~8kg It was determined that the value of / cm 2 is preferable. This is because if the pressing pressure of the buff roll for mirror polishing against the stainless steel strip is less than 2 kg / cm 2 , not only will the number of polishing be increased and it will be inefficient, but also surface defects such as spots on the surface of the steel strip will be removed. It is not preferable because it becomes difficult to perform and polishing is insufficient and satisfactory mirror polishing cannot be performed.On the other hand, when it exceeds 8 kg / cm 2 , the pressing pressure rises too much and the temperature of the buff material rises and This is because it is not preferable because the service life is shortened and buff burning occurs on the surface of the stainless steel strip.

るので好ましいのである。As described above, in the present invention, for mirror polishing, which is rotating at a peripheral speed (m / min) that is relatively significantly larger than the threading speed (m / min) of the stainless steel strip to be threaded. By using a buff material that allows the buff roll to increase the pressing pressure on the stainless steel strip, it is possible to perform mirror polishing, but in addition to this, as condition d at the end, a proper amount of abrasive is not wasted. It is important to supply evenly and evenly. For this purpose, a liquid abrasive containing fine abrasive grains is air-sprayed toward the contact start site between the surface of the mirror-polishing buffalo or the surface of the roll and the surface of the stainless steel strip to be passed, that is, with air. Most preferably, it is sprayed in the form of mist and supplied. Moreover, as the fine abrasive grains contained in this liquid abrasive, acid-colored aluminum, which is a white and stable oxide, is stable and has excellent polishing ability, and it does not feel uncomfortable with the color tone of the background of stainless steel and is well matched. However, it is preferable that the steel strip or the product does not contaminate the mirror polishing site such as equipment, which is accompanied by a changed color or chemical change like other abrasive grains. Although a solid abrasive is also used as the abrasive, a liquid abrasive is preferable in this case because it can be uniformly and uniformly supplied.

を行つた。Next, this woven fabric 1 is cut into a bias shape and attached to the metal fitting 6 so that the cutting edge is located on the outer periphery. As shown in FIG. 2, 57 buff wheels are incorporated into the shaft 5, and the nut 4 is inserted through the washer 3. Then, the buff roll 1 shown in FIG. 1 was placed in the form of a mirror polishing roll having a diameter of 350 mm and a buff body length of 1300 mm. The buff roll 1 arranged in this way is made of steel type SUS304 and SUS430 and has a plate thickness of 0.1 to 2.0 mm.
In addition, a stainless steel strip S having a plate width of 500 to 1250 mm is passed through the air spray gun 7 while spraying the liquid abrasive toward the site where the surface of the buff roll 1 and the steel strip S start to contact. The plate was then subjected to continuous mirror polishing under the following conditions.

As a result of continuous mirror polishing under 3.3 cc (3.9 to 7.1 gr / m 2 ) or more, the surface gloss is much better than the conventional one, and this high gloss surface is buffed to a mirror surface with excellent image definition. The obtained stainless steel strip could be obtained. This image clarity (Distinctness of Im

大きなものがある。The polishing baffle used for carrying out the mirror-polishing method for a stainless steel strip according to the present invention described in detail above is a buff material for mirror-polishing a stainless steel strip made of a viscose rayon filament having a denier of 500 denier or more. Since it has been hardened, it can withstand higher temperatures than conventional ones and can extend the service life without changing the quality of the buff material. The pressing pressure of the mirror polishing buff roll, which rotates at a significantly high peripheral speed of 1900 to 2500 m / min, on the stainless steel strip is the same as the pressing pressure of the conventional mirror polishing buff roll on the stainless steel strip. 1-5.6 kg / cm 2 compared
Since it can be as high as 2 to 8 kg / cm 2 , the polishing power is 1.6 times higher than that of the conventional woven fabric made of cycle hemp and cotton buff, and the polishing efficiency is also twice as high as the conventional one. Further, the method of the present invention uses a buff roll for mirror-polishing in which a woven fabric made of viscose rayon filaments having a denier of 500 denier or more is hardened and cut into a bias to form a polishing surface at the cutting edge. It is a method of specularly polishing the surface of a stainless steel strip satisfactorily and efficiently by defining the optimum conditions for, and according to the method of the present invention, even fine surface defects such as patterns generated on the surface of the stainless steel strip can be obtained. It can be easily removed, and the essential surface gloss and image clarity as a mirror surface can be greatly increased compared to conventional mirror polishing methods without causing buff burning on the steel strip surface. The value is very large.
