In other words, those with bright finished surfaces (B, C,),
Those having dull finished surfaces (D, C,) that are slightly rougher than the bright finished surface but sufficiently flat are generally used.

されていないのが現状である。The above-mentioned rolled plate is used as food cans etc. by painting after processing.
Because they are used for long periods of time in a harsh corrosive environment, thread-like corrosion occurs in the A1 or A1 alloy material due to moisture that enters through paint film defects such as scratches and paint pinholes during use.
This caused problems with the appearance and required repair of the corroded parts. Conventionally, improvement of painting technology and paint, or improvement of AI material itself (chemical composition, i-weave, manufacturing process)
Although efforts have been made to prevent corrosion, the problem is not yet completely resolved.
［発明の目的１
本発明は、上記の問題に鑑みてなされたものであって、
圧延板の材料やその！ｌ織等を変更することなしに圧延
板の耐糸さび性を向上させることを目的とする。[Object of the invention 1 The present invention has been made in view of the above problems, and includes:
Materials for rolled plates! The object of the present invention is to improve the yarn rust resistance of a rolled plate without changing the weave or the like.
［発明の背景１
本発明者は、試験を行った結果、圧延板の表面をある程

させうるという知見を得た。その理由は判然としないが
、糸さびの進行が板表面の凹凸に上ってさまたげられる
ものと推測される。[Background of the Invention 1] As a result of conducting tests, the present inventor found that by roughening the surface of a rolled plate to some extent, yarn rust resistance can be significantly improved. The reason for this is not clear, but it is assumed that the progression of thread rust is hindered by climbing onto the unevenness of the board surface.
なお、圧延板の表面粗さの評価基準としては、最大ネ■
さＲｗａｘとＰ Ｐ Ｉ （ｐｅａｋ ｐｏｉｎｔ ｐ

・・・、Ｍの個数と、２５μインチ以上の深さを有する

本発明者の行った試験においては、Ｒｗａｘを２μｍ以

好な耐糸さび性が得られた。すなわち、Ｒ＋ｏａｘが２

好な耐糸さび性が得られる・ものの、実際にＰＰＩを４
００個以上に設定することは現状の生産設備上困難であ
り、且つ仮９に４００個以上に設定しえたとしても充分
な量産性を得ることは難しいので、ＰＰＩは３０〜４０
０個の範囲に設定することが好ましい。In tests conducted by the present inventor, good yarn rust resistance was obtained when Rwax was set in a range of 2 μm or more and PPI was set in a range of 30 or more. That is, R+oax is 2
Less than μ inch or PPI (h≧25 μ inch) is 30
If the PPI is less than 400, the thread rust resistance of the rolled plate will not improve much.If the PPI exceeds 400, extremely good thread rust resistance will be obtained.
It is difficult to set it to more than 00 pieces due to the current production equipment, and even if it were possible to set it to more than 400 pieces, it would be difficult to achieve sufficient mass productivity, so the PPI should be 30 to 40.
It is preferable to set it in the range of 0.
又、ＲｍａｘとＰＰＩは圧延板の全ての方向の１° イ

ＰＰＩの測定の容易性及び圧延板の量産性等の観点から
、少なくと６２方向、つまり、圧延方向と平行およびび

した。Also, Rmax and PPI must be within the above setting range within a length of 1° inch in all directions of the rolled plate, that is, each peak (or valley) should be in an independent conical shape. However, from the viewpoint of ease of measurement of Rmax and PPI and mass production of rolled plates, it is desirable to have the above-mentioned shape in at least 62 directions, that is, in directions parallel and perpendicular to the rolling direction. It is assumed that it is acceptable as long as it falls within the setting range.

コスト高になるので実用上不利である。Note that methods for roughening a rolled sheet include (i) rolling with a rolling roll whose surface has been roughened and transferring the rough surface shape of the roll surface to the rolled material, and (ii) chemical treatment after rolling. (etching, etc.) or electrochemical treatment, etc., but method li) increases the number of steps and costs, so it is disadvantageous in practice.
