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 by suppressing 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 μm. La présente invention concerne un procédé de passage de tôle pour une tôle d'acier, un équipement de production pour une tôle d'acier mince, et un procédé de production pour une tôle d'acier qui permettent de réduire les coûts de production de produit en supprimant l'apparition d'anomalies de qualité dans les surfaces des tôles d'acier, et des tôles minces en particulier, et en prolongeant le cycle de remplacement d'un rouleau. Le procédé de passage de tôle destiné à une tôle d'acier utilise un rouleau presseur de tôle d'acier qui comporte une couche pulvérisée embrevée formée sur sa surface. La surface du rouleau presseur de tôle d'acier présente une Rpk de 2 à 12 µm. 鋼板、特に薄板の表面の品質異常の発生を抑制するとともに、ロールの取替周期を長くすることによって、製品の製造コストを低減することのできる鋼板の通板方法、薄鋼板の製造設備及び鋼板の製造方法を提供する。表面にディンプル溶射層が形成され、表面のＲｐｋが２μｍ～１２μｍである鋼板接触ロールを用いた鋼板の通板方法である。
