るという問題点があった。2. Description of the Related Art A stainless steel strip is generally rolled by a cold rolling mill such as a Sendzimir rolling mill. The steel strip supplied to the rolling mill is rolled through several passes to a predetermined thickness. As a surface defect of the steel strip generated by cold rolling, a hard foreign substance such as a metal piece adhered to the steel strip surface is rolled by rolling together with the steel strip, and a soft foreign substance such as a rubber powder adhered to the steel strip surface. Biting flaws caused by rolling with a steel strip can be cited. As a technique for preventing such a surface defect of a steel strip, for example, Japanese Unexamined Patent Publication No.
No. 8309 discloses that using a brush-type plate surface cleaning device, in the vicinity of a welding point of a steel strip, the brush rotation speed or the brush rolling force is increased to remove hard foreign substances adhering to the surface,
In other places, operating methods have been proposed to reduce the brush speed or the brush rolling force. According to this method, generation of roll mark flaws due to hard foreign matter can be prevented, and the life of the brush is increased. However, such a cleaning method using a brush has a problem that, in a steel type such as a stainless steel strip which requires a glossy surface, a bite flaw is generated due to the depilation of the brush, which causes a deterioration in quality. there were.

た。[0003] In the stainless steel strip supplied to the cold rolling mill, as shown in FIG. 3, defects on the material surface such as barbs generated on the surface and grain boundary erosion grooves generated during pickling have been conventionally known. While the polishing liquid was supplied from the polishing liquid supply header 21, the polishing liquid was removed by polishing with a polishing belt 20 to which abrasive grains were adhered. The polishing belt 20 is driven by a driving roll 23 and an idle roll 22 to polish the stainless steel strip 1 with a backup roll 24. Then, a wiping device 18 is provided on the exit side of the polishing device 26 to remove polishing liquid remaining on the surface of the steel strip after polishing. However, the remaining polishing liquid contains a large amount of polishing powder of the steel strip generated during polishing and abrasive grains of the polishing belt, and even if the polishing liquid is removed by the wiping device 18, much of the polishing powder and abrasive grains are present. Remains on the steel strip surface. For this reason, the steel strip is wound up with the abrasive powder and abrasive grains attached to the surface. At present, the steel strip was sent to a rolling mill with foreign substances adhered to the surface.

This was performed by spraying the rolling oil from the rolling oil supply header 17 between the work roll 16 and the work roll 16. However, when a large number of foreign substances are adhered to the steel strip to be rolled, the foreign substances are removed by spraying the rolling oil, but the removed foreign substances are mixed into the rolling oil and removed together with the rolling oil. The contaminants were bitten by the work roll 16, and the roll was dented and transferred to the steel strip to form a convex flaw, a biting flaw, or directly adhered to the steel strip, resulting in contamination of the steel strip.

Therefore, the steel strip supplied to the cold rolling mill is
It has been demanded to have a clean surface that prevents foreign substances from adhering to the surface.
