  • Rolling of hot strip and strip defects – IspatGuru

     · Mill spring causes the thickness of the strip exiting from the rolling mill to be greater than the roll gap set under noload conditions. Precise thickness rolling requires the elastic constant of the mill. Calibration curves are needed. The elastic constants are usually in the range of 1 GNm1 to 3 GNm1 for screwloaded rolling mills and around 4 GNm1 for hydraulically loaded mills. Due to ...
