After polishing to a predetermined surface roughness by belt polishing, the stainless steel plate is rolled by a work roll having a specific surface roughness, so that the metallic luster formed in one direction by belt polishing is reduced. As a result, antiglare properties can be imparted to the steel sheet surface.

場合の圧延率を、例えば１０〜２０％とすることによ
り、良好な防眩性を得ることができる。The degree to which the surface roughness of the work roll used for rolling is transferred to the steel sheet is affected by the rolling reduction in the rolling pass, the deformability of the steel sheet, and the rolling conditions (speed, presence or absence of lubricating oil, etc.). Although the relationship between the surface roughness of the work roll used and the surface roughness (polished surface roughness) Ra (A) of the steel sheet formed by belt polishing cannot be strictly defined, the polished surface roughness of the steel sheet However, when there is a significant difference from the surface roughness of the work roll to be used (for example, the polished surface roughness Ra (A) is 20 to 40 μm and the roll surface roughness Ra of the initial rolling pass is 0.5 to 1 μm). Except for the case where the rolling ratio in finish rolling is set to, for example, 10 to 20%, good antiglare property can be obtained.

となる。When the rolling ratio is 10% or less, the transfer of the surface roughness of the work roll is insufficient, and when the rolling ratio is 20% or more, not only is it unnecessary to obtain a desired surface state, but also the material is processed. Since curing proceeds, heat treatment for softening is indispensable.

少させることができる。[0015] In the present invention, after the belt polished steel plates, and the rolling of the first pass in the first work roll having a small surface roughness than the surface roughness formed by the belt polishing, furthermore, the so as to rolling the second pass in a second work roll having a larger surface roughness than 1 work rolls
ing. Therefore , the roughness of the first work roll, which has been slightly finely finished in the first pass of finish rolling, is transferred to the polishing eye formed of long irregularities aligned in one direction caused by belt polishing, and then the second work having a large roughness is transferred. By rolling using a roll, the unidirectionality of the polished eyes can be disturbed, so that the glittering metallic luster along the polished eyes can be reliably reduced.
【００１６】これを更に詳細に説明すると、まず、艶消

The surface of the steel plate is polished to a predetermined surface roughness by belt polishing.

面の細かい研磨目を研磨面に転写することができる。However, in this state of the polished surface, as described above, the directionality of the polished eyes is remarkable, so that the polished surface is insufficient as a matte surface. Therefore, first, in the first pass, rolling is performed under light pressure using a first work roll having a relatively finely finished surface roughness. That is, the first work roll is appropriately rolled to smooth the polished surface while leaving a relatively deep portion in the polished eyes formed by the belt polishing, thereby dividing the long polished eyes, The fine polishing marks on the roll surface can be transferred to the polishing surface.

に、適度な凹凸を付与することができる。Thereafter, the steel sheet is rolled using a second work roll that is finished coarser than the first work roll in the second pass,
By transferring the polished eyes of the rough roll to the polished surface,
It is possible to further divide the long polished stitches formed by the previous belt polishing and to provide appropriate irregularities.

面が得られる。By performing the above-described processing, the divided deep grooves (the belt-polishing line and the coarse second-work-roll-side polishing line (surface roughness)) can be formed based on the belt-polishing line. A transfer surface) and a fine unevenness (a transfer portion of a finely polished stitch (surface roughness) of the first work roll) are combined, so that a calm matte surface with less directivity is obtained.

関係があることが時に好ましいことが分かった。As a result of a detailed study by the present inventor, it has been found that it is sometimes preferable that the following relationship be established between each roughness combination in order to obtain good surface properties.

If the surface roughness is too fine, the antiglare property is inferior. If it is too coarse, it is easily stained, and the stain removal property during washing is poor.

The work roll smoothes the polished surface of the steel sheet, and furthermore, the second work roll having a large surface roughness is used for the basis weight, so that the belt polishing line is cut off, and the polished surface characteristics due to the belt polishing are reduced, and as a result, the directionality is reduced. A surface with little anti-glare properties can be obtained.
