本発明は、ステンレス冷延鋼帯の製造工程の最終段階で
あるレベリング工程において良好な表面性状を得る方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a method for obtaining good surface quality in a leveling step, which is the final step in the manufacturing process of cold-rolled stainless steel strip.

覧６２２〜６２８頁）。Stainless steel cold-rolled steel strip is made from hot-rolled steel strip that has been annealed and pickled, and has various surface finishes specified in JISG4307 by cold rolling, annealing and pickling, bright annealing, temper rolling, belt polishing, etc. made of steel strip. (Stainless steel handbook pages 622-628).

が行われる。At the final stage of this cold-rolled steel strip manufacturing process, if it is necessary to produce a cold-rolled steel strip with a better shape of flatness, or by continuously cutting the cold-rolled steel strip to produce cold-rolled steel sheets with predetermined dimensions. When manufacturing, leveling work is performed to correct the shape.
ステンレス冷延鋼帯のレベリングは通常ロラーレベリン

われている。Leveling of cold-rolled stainless steel strips is usually performed using a roller leveling device or a tension leveling device.

面性状が損なわれることはほとんどない。[Problems to be Solved by the Invention] When a cold rolled stainless steel strip passes through a leveling device, the surface of the steel strip is pressed by a metal leveler roll, so metal contact may occur or the surface of the cold rolled stainless steel strip may Especially in the case of 2B finished products, which account for the majority of finishes, the surface quality is hardly impaired.

を生じるようになった。However, in the case of stainless steel cold-rolled steel strips whose surfaces are dull-finished using dull rolls in the rolling process, the convex portions of the surface irregularities are pressed against the leveler rolls, resulting in a glossy appearance, resulting in a glossy overall appearance. A phenomenon occurs in which the aesthetic appearance of the eraser is impaired. Up until now, many dull-finish products were ultimately used after being painted, so this did not pose a problem, but recently, as they have been increasingly used unpainted as exterior materials for building materials and vehicle materials, the aesthetics have become a problem. This started to cause problems.

る場合がしばしば発生するという問題があった。In addition, the surface was polished to No. 1 by belt polishing. When a cold-rolled stainless steel strip with a polished finish such as 4 or HL finish is passed through a leveler, the grinding debris adhering to the surface of the steel plate will adhere to the leveler roll, creating continuous indentation scratches on the surface of the steel strip. The problem is that cases often occur.

しばしば生していた。In addition, in the case of BA finished products with extremely smooth surfaces and extremely high surface gloss, if minute airborne particles on the steel strip surface adhere to the leveler roll and cause small indentation scratches, r3A finish may occur. Due to the two products, conspicuous defects often occurred.
本発明はステンレス冷延鋼帯をレベリングする際に生し

。The present invention provides a method for solving the above-mentioned problems that occur when leveling cold-rolled stainless steel strip.
〔課題を解決するための手段１
本発明者らは前記問題点を解決する方法として大がかり

テンレス冷延鋼帯が得られることを発見した。[Means for Solving the Problems 1] As a method for solving the above-mentioned problems, the present inventors have investigated various methods that are simple and have remarkable effects without involving large-scale equipment modification. It has been discovered that by passing the plate through a leveling device while it is attached to the surface, a cold-rolled stainless steel strip with good surface quality can be obtained without impairing the leveling effect.

ィルムを貼り付け、レベリング装置を通板させることを
特徴とするステンレス冷延鋼帯のレベリング方法である
。That is, the present invention is a method for leveling a cold-rolled stainless steel strip, which is characterized by pasting a protective film on the surface of the cold-rolled stainless steel strip and passing the film through a leveling device.
〔作用１
本発明で用いる保護フィルムは塩化ビニール、ポリエチ
レン等の合成樹脂フィルムめ片面にアクリル系あるいは
ゴム系の粘着剤を塗布したものである。[Function 1] The protective film used in the present invention is a synthetic resin film such as vinyl chloride or polyethylene with an acrylic or rubber adhesive coated on one side.
保護フィルムの厚みは、薄すぎるとダル表面凸部の保謁
作用と押込疵防止効果がなくなり、また厚すぎると鋼帯
のレベリング効果が損なわれるので、３０〜２００μ程
度が好ましい。フィルム自体の材質は特に問わないが塩
化ビニール系、ポリエチレン系が経済性の点から好まし
い。The thickness of the protective film is preferably about 30 to 200 microns, because if it is too thin, the protective effect of the convex portions on the dull surface and the effect of preventing indentation scratches will be lost, and if it is too thick, the leveling effect of the steel strip will be impaired. The material of the film itself is not particularly limited, but vinyl chloride and polyethylene are preferred from the economic point of view.
ステンレス鋼帯に対する保護フィルムの粘着力は、弱す
ぎるとレベリング製訳通過時保諾フィルムがつれてしわ
が入りやすくなり、また強すぎるとレベリング後保訝フ
ィルムを除去する場合に保護フィルムの除去が困難とな
ったり、保護フィルム除去後の鋼帯表面に粘着剤が残る
などの不都合が生じる。したがって、対象とするステン
レス冷延鋼帯の表面仕上げや板厚さに応じて適度な粘着
力を有する保護フィルムを選定する必要かある。If the adhesive strength of the protective film to the stainless steel strip is too weak, the protective film will tend to get wrinkled when passing through leveling, and if it is too strong, it will be difficult to remove the protective film when removing the protective film after leveling. Inconveniences may occur, such as making it difficult to remove the protective film or leaving adhesive on the surface of the steel strip after removing the protective film. Therefore, it is necessary to select a protective film with appropriate adhesive strength depending on the surface finish and thickness of the cold-rolled stainless steel strip.
ステンレス鋼帯に保謹フィルムを貼りつける方法は、コ
イル状の保護フィルムを巻き戻しながらステンレス鋼帯
表面に連続的に貼りつける簡単な装置を用いて容易に行
うことができる。The method of attaching the protection film to the stainless steel strip can be easily carried out using a simple device that continuously attaches the coiled protective film to the surface of the stainless steel strip while unwinding it.
