Abstract: PURPOSE: A method for inhibiting ridging of Al-Mg-Si alloy sheet is provided to suppress development of Goss orientation and substantially reduce ridging of the alloy sheet accordingly by properly controlling shape factor (l/d) related with size and reduction ratio of rolling rolls in the rough rolling step during hot rolling. CONSTITUTION: The method comprises the process of maintaining shape factor (l/d) in front of rough rolling represented in the following mathematical expression to 0.8 or less and maintaining shape factor (l/d) in rear of rough rolling to 0.5 or more as maintaining frictional coefficient of rolling rolls with the work to 0.1 or less in the rough rolling step when hot rolling an alloy slab in the manufacturing process of the Al-Mg-Si alloy sheet. In mathematical expression, l is length of the roll projected on the sheet in a rolling roll bite, d is an average thickness of the sheet, R is radius of the rolling rolls, di is an initial thickness of the sheet, and df is a final thickness of the sheet.
