Abstract :
The accuracy of looper length calculation is highly significant in the looper control system of hot strip rolling mills. This paper described the precise calculation formula, the isosceles triangle approximate calculation formula and Taylor series expansion approximate calculation formula used in looper length calculation. The accuracy of these three formulas is compared in 1580 mm, 1700 mm and 2050 mm hot strip rolling mill. In conclusion, the isosceles triangle approximate calculation formula is proved to be with the advantage of high accuracy and simple models.
