Abstract

PURPOSE:To roll accurately a material in its width direction by calculating a gauge-meter sheet width based on a specific equation and controlling the rolling- reduction schedule of edger rolls. CONSTITUTION:When a rolling material is sent to a rolling mill for rolling it, a sheet-width-quantity arithmetic unit inputs from a measuring device the measured value PEA of the rolling load of material during rolling and the measured value EGAPA of the roll gap between edger rolls. And a gauge-meter sheet width Bg is calculated based on the equation, (where, ME: mill constant, a, b: constants). Then the rolling reduction schedule of edger rolls is controlled in accordance with the gauge-meter sheet width Bg.
