But, I don't think that you need to flatten the plate. Re-rolling can be done on the already rejected rolled cylinder. Sometimes we do the same when rolling large diameters with high thickness. It happens some times that the first rolled course, after welding, goes behind the acceptable limits. We have never flatten it before. we re-roll the same even after welding.
