Analysis of roll stack deflection in a hot strip mill - SciELO

As the length of the work roll and back up roll are equal, the effect of roll bending is not prominent to reduce the crown. To obviate this problem, the use of tapered crown work rolls in a Japanese steel plant, as mentioned in the paper by Kitahama et al. (1987), was introduced, where shifting of the work roll was made to compensate for crown developed.
