Beschreibung
Zusammenfassung:	Provided are a sheet-passing method for a steel sheet, production equipment for a thin steel sheet and a production method for a steel sheet that make it possible to reduce product production costs bysuppressing the occurrence of quality abnormalities in the surfaces of steel sheets, and thin sheets in particular, and by extending the replacement cycle of a roll. The sheet-passing method for a steel sheet uses a steel sheet contact roll that has a dimpled sprayed layer formed on the surface thereof. The surface of the steel sheet contact roll has an Rpk of 2-12 [mu]m. 本发明提供一种通过抑制钢板，特别是抑制薄板的表面的品质异常的产生并延长辊的更换周期而能够降低制品的制造成本的钢板的通板方法、薄钢板的制造设备及钢板的制造方法。是使用了在表面形成有凹坑喷镀层且表面的Rpk为2μm～12μm的钢板接触辊的钢板的通板方法。
