Abstract (en)

[origin: WO0228558A2] This invention provides a sheet width control method, in hot rolling, that calculates a sheet width distribution of a rolling material in a longitudinal direction and its temperature on the entry side of a vertical rolling mill set as the object for controlling the sheet width, further calculates a distribution of sheet width change amounts of the rolling material along the longitudinal direction occurring on the downstream side to the vertical rolling mill along a rolling direction, and calculates and controls roll gap of the vertical rolling mill in the longitudinal direction of the rolling mill on the basis of a sheet width distribution of the rolling material determined from the distribution of the sum of the calculated sheet width change amounts along the longitudinal direction and on the basis of a final target sheet width.
