Abstract

PURPOSE:To prevent a crack in a sheet end by operating the minimum value of sheet width immediately before edging from the quality, shape of initial dimensions and pass schedule of a stock to be rolled, and setting a gap between an edging roll and the sheet end. CONSTITUTION:A numerical expression 14 of dimensional model is prepared in consideration of the quality 11, shape 12 of initial dimensions and pass schedule 13 of a stock W to be rolled. Next, the minimum dimension 15 of sheet width necessary for bringing the sheet end of stock W into contact with an edging roll 10 through its whole surface, is operated by the expression 14. At the time of setting a roll gap, a roll gap 16 that makes the sheet end contact through its whole surface is added to set a roll gap 17 to the rolls 10. In this way, a crack in the sheet end is prevented in edging, and the quality of a rolled product is improved.
