で均一な研摩面になるというものである。[Prior Art] A known method for manufacturing polished stainless steel sheets is disclosed in Japanese Patent Application Laid-Open No. 168907/1983. This is done by surface polishing after cold rolling, followed by annealing and pickling.
Then, if necessary, temper rolling is performed to form a fine and uniformly polished surface. The effect of this invention is that scale is generated on the surface of a very sharp abrasive stone formed by a belt etc. by annealing, and then the scale is removed by pickling. As it falls off or dissolves and becomes lower, the abrasive stone becomes smoother, resulting in a fine and uniform abrasive surface when viewed from a macroscopic perspective.

るという問題点を有している。However, as stated in the specification, the polished stainless steel sheet produced through the process of cold rolling → polishing → annealing → pickling → temper rolling has a surface that is not polished like a conventional polished surface. The problem is that the metallic color is not strong and the appearance is soft.

巻き取られる。A system diagram of a conventional polishing and cleaning apparatus is shown in FIG. 2. A stainless steel plate is rewound from a payoff reel l and guided to a deflector roll 2, and is polished by a polishing belt 4 on a billy roll 3. Next, it passes through a ringer roll 5, is sprayed from a spray nozzle 10, and is brushed with a brush roll 7, dried with a dryer 8, and wound up on a tension reel 9.

材で研摩したものである。The finished surface of a polished stainless steel plate is determined by JIS. For example, No. 0, 3 finish is a 2B or 2D plate that has been softened and annealed and polished with an abrasive of No. 100 to 120, and No. 4 finish is the same. It was polished with abrasives number 350-180.

は出ない。[Problem to be Solved by the Invention J] When a polished stainless steel plate is cold-rolled and then polished, then annealed and pickled, the color tone of one surface changes greatly from that of conventional products. For this reason, coarsening the abrasive material improves the soft appearance to some extent, but the metallic color does not appear as with conventional products.
すなわち、このプロセスで製造した研摩仕上ステンレス
鋼板は特殊な用途には有用であるが1世間一般に通用す
る汎用性がないという問題を有している。That is, the polished stainless steel sheet manufactured by this process is useful for special purposes, but has the problem that it is not versatile enough to be used by the general public.
また、研摩仕上ステンレス鋼板は、その表面に研摩部が
多く著しく歩走りが低いという問題点がある。Furthermore, the polished stainless steel plate has a problem in that its surface has many polished parts and its walking speed is extremely low.
JISで決められた表面仕上のステンレス鋼板を得るた
めには金属光沢を出すために最終工程で研摩仕上を行う
必要がある。In order to obtain a stainless steel plate with the surface finish specified by JIS, it is necessary to perform a polishing finish in the final process to produce a metallic luster.

が鋼板に押込まれ押込み疵となる。At this time, on the surface of the polished steel plate, there are countless polishing scum in the form of very sharp steel pieces. When this polished steel sheet comes into contact with a priddle roll, skin bath roll, leveling roll, etc., the polishing scum adheres to the roll surface and is pushed into the steel sheet, resulting in indentation flaws.
この研摩カスは研摩面の溝部に付着しているから、洗浄
用ブラシ、超音波洗浄等の洗浄方法では除去できない。Since this polishing scum adheres to the grooves of the polished surface, it cannot be removed by cleaning methods such as a cleaning brush or ultrasonic cleaning.

るロール表面に付着するわけである。However, the abrasive scum that adheres to each roll can be removed from the roll surface extremely easily by washing with water, and the abrasive scum surface adhesion rate, that is, the ratio of how much abrasive scum adheres to the roll surface, is higher on the Pridle roll than on the Deflect roll. Furthermore, it was found that rolling rolls are larger than bride rolls.6 In other words, the greater the degree of working on the abrasive surface, the more the abrasive scum separates from the abrasive surface, and It sticks to the surface.

とを目的とするものである。Based on the above knowledge, the rolling roll is installed in a cleaning tank for degreasing that is attached to the polishing process, and light rolling is performed here to peel off the polishing scum, and then the rolling roll and the polished surface are cleaned. It was found that by removing abrasive scum, it is possible to prevent roll flaws caused by adhesion of abrasive scum on the priddle rolls, leveler rolls, etc. that are subsequently passed through.
It is an object of the present invention to provide such a novel method and apparatus.

This is a method for manufacturing a polished stainless steel sheet characterized by performing a light reduction in the range of 3.0% to 3.0%.

After the roll surface and Fffff surface after rolling are cleaned, the product is wound onto a tension reel. In contrast to the prior art, JP-A-56-168907, in which annealing and pickling were performed after polishing, the present invention is characterized in that a light rolling process is provided after the polishing process as a countermeasure against indentation scratches. It is something that exists.

ある。0.1%よりも少ない圧下率では研摩カスの除去

が増加してくる。The rolling reduction ratio in the light rolling step is preferably 0.1 to 3.0%. If the rolling reduction is less than 0.1%, the effect of removing abrasive scum will not be sufficient, while if the rolling reduction exceeds 3.0%, there will be no difference in the effect, and on the contrary, the disadvantage of wear of the rolling rolls will increase.

m以上が好ましい。There are no particular regulations regarding the amount of spray applied to the roll bite portion, roll surface, and polished surface, but it is generally preferred that the spray amount be equal to or greater than lOβ/m1nx plate width m.
