Abstract
PURPOSE: To make possible the exact thickness control even though the roll material and shape are changed, by carrying out the thickness control according to the formula in which the term representing the roll deflection is corrected with Young's modulus, etc., being based on the gaugemeter formula.
CONSTITUTION: The gaugemeter formula of BISRA being used in the conventional thickness control for the rolled sheet, is corrected into the formula (I) [H is for predicted thickness mm, S0 for roll gap mm, M for mill stiffness t/mm, F for rolling load, t for correction term for oil film pressure ρoil(mm), OFFSET for offset value mm, and Y for correction term corresponding to the roll]. Above correction term Y is given by the formula (II), in which E is for Young's modulus of the roll, I for second moment of area, F for rolling load, and W for breadth of rolled material. As above stated, even if the material and shape of the roll are changed, the deflection of the roll due to these changes is corrected; hereby, more exact control of the thickness can be carried out as compared with the conventional method taking the mill stiffness M as constant.
