  • How Important Is Sheet And Plate Steel Flatness

    This is because the rolling mill uses that crown to aid tracking in the mill.Under the huge forces applied, the temper mill rolls deflected slightly because of the crown.This contributed to the marginally out-of-flat numbers observed.Parts cut closer to the sheet edges exhibited more out-of-flat conditions than those cut from the middle two.
