Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method and apparatus for calculating a wall thickness capable of correctly and responsively calculating the wall thickness beneath a roll. SOLUTION: A roll axial rotational speed is estimated from rolling records using an observer, and a roll peripheral speed is calculated from the roll axial rotational speed, and by using the roll peripheral speed, the wall thickness can be calculated in accordance with a mass flow formula.
