Abstract

A sheet hot rolling mill, wherein its finishing rolling mill (30) is divided into front and rear stages (31 and 32), and CVC mills (31A and 31B) of two stands or more are disposed on the front stage (31) and different diameter roll mills (32A and 32B) of two stands or more are disposed on the rear stage (32), whereby, when a thin sheet about 1.2 mm thick or thinner is rolled, a crown or edge drop is suppressed from occurring and also a drawing is prevented from occurring at the tail end part of the sheet so that a rolled sheet can be manufactured smoothly.
