Tags Pickle Lines, Rolling Mills; Temper Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1% to 2% in thickness. This can be done on a coil-to-coil temper pass mill or in line on a cut-to length line.
Roll change cars for all skin-pass mills. The modern design of this system allows rolls to go through the mill stand or side changing system, depending on specific needs. Combined with a fast roll changer car, this design is the ideal system for a fast and effective roll change and is particularly well adapted to in-line DMS SkinPass mills.
