| Abstract Scope |
In temper rolling of double reduced thin sheet strips, shape defect called “longitudinal buckling” appears. In previous study, the effect of several rolling conditions on the longitudinal buckling was investigated. However, effect of delivery angle over 4 degree has not been experimented. In this paper, effect of large delivery angle is investigated in laboratory rolling. Results show that by increasing delivery angle, the buckling appears clearly and the number of waves decreases, and by delivery angle over 24 degree the buckling disappears. Next we calculate the buckling characteristics of the sheet which twines around the work roll by the elementary theory. We find that the change of number of waves by delivery angle calculated from the analysis almost agrees with the experimental result when delivery angle is larger than 10 degree. It is estimated that the shape of sheet which twines around the work roll affects the longitudinal buckling phenomenon. |
