Abstract (en)

[origin: EP1033182A1] A finishing mill (30) included in a hot rolling mill system has a front stage (31) and a back stage (32). The front stage (31) is provided with two or more CVC rolling mills (31A, 31B) and the back stage (32) is provided with two or more different-diameter-roll mills (32A, 32B). When producing a thin sheet of 1.2 mm or below in thickness by rolling, the formation of crown and edge-drop can be suppressed and the formation of pincher in a tail end part of the sheet can be prevented, so that a rolled sheet can be smoothly manufactured. <IMAGE>
