Abstract

PURPOSE:To control accurately the sheet width of a rolling material to a prescribed value by changing a gain of an automatic sheet width controlling system before and after a changing point, in case of changing the sheet thickness of a material while rolling it, in a hot continuous rolling mill. CONSTITUTION:In case when the thickness of a rolling material 10 is changed on the way of hot rolling while running the material 10, a roll gap and a rolling force of an edger 3 are locked on storage circuits 24, 26 immediately after a changing point of sheet-thickness passes through the edger 3. These values are used as a reference roll gap S0 and a reference rolling force P0 of the edger 3, in a sheet thickness controlling thereafter. At the same time, a gain changeover circuit 30 is actuated to change a gain G1 of a position-calculating-reference circuit 29. Thus, the sheet thickness of the material 10 is accurately controlled to a prescribed value.
