Main Features of a modern Hot Strip Mill – IspatGuru

Either RF-AGC or Mon-AGC of AGC(automatic gauge control) model to the 1580 hot strip rolling mill belongs to a feedback control system.Time lag is therefore inevitable to the readjustment of rolling gap,thus resulting in the constraint on improving the strip gauge precision.The normal feedforward idea about tandem cold mills was introduced into hot strip rolling to develop a feedforward AGC ...

Rolling of steel in Hot Strip Mill – IspatGuru

Jun 27, 2008· Abstract: Mill Modulus Control (MMC) is one of important methods on Automatic Gauge Control (AGC) systems of strip rolling mills. It would result in a slower adjusting speed of strip rolling gap to combine the former AGC system and MMC simply without changing the compensating coefficient of rolling efficiency, which was deduced in detail by some inferential reasoning formulas.
