<p>PURPOSE: To improve passability of rolled material and yield in width by reducing camber generated in rolling to produce metal sheet. CONSTITUTION: In the camber reducing method in a metal sheet rolling line, in which a vertical rolling mill 2 and horizontal rolling mill 4 are arranged, the thickness distribution of rolled material 1 in the sheet width direction and the position of both ends of in the sheet width direction are measured with a shape measuring instrument 3 arranged between the vertical rolling mill 2 and horizontal rolling mill 4, the deformed shape of both ends in the thickness direction near rolled material tip part and the off-center quantity from the line center of center line of rolled material are obtained from the measured result. By operating the variation quantity of roll gap interval of left/right of the horizontal rolling mill 4 required for reduction of camber from the obtained result, the roll gap interval is adjusted.</p> |
