Roll Pass

Roll Pass Design

Roll Pass Design projects can include:

  • Flow charts
  • Detailed pass design
  • Process simulation of rolling for calculating motor sizes, gear ratios, and rolling forces
  • Roll barrel layouts
  • Set-up sheets
  • Start-up and commissioning services

Our design expertise encompasses:

  • Rounds and Rod
  • Rebar (including slitting)
  • Flats
  • Angles
  • Channels
  • Beams
  • Rails ­ Standard and Special
  • Universal rolling of structural, rail, and special sections
  • Other special sections such as: track shoes, sheet piles, rails, and other non-symmetrical special shapes

Our design expertise extends to almost all hot rolled metals:

  • Carbon Steels
  • Alloy Steels
  • Superalloys
  • Copper
  • Aluminum

Roll Pass Designs projects typically follow the following timeline:

  • Development of the engineering documentation, including detailed groove drawings, roll barrel layouts, roll stress calculations, rolling power, torque and separating force predictions, and roller set-up sheets.
  • Design review and training sessions when the above documentation is presented to the mill operations personnel, in order to facilitate the understanding of the theory behind the design. Rolling practice for start-up will be reviewed and agreed upon at this time.
  • During commissioning, pass design engineers will be on site to assure smooth start-up and accurate data collection for documentation and feedback for later analysis and reporting.
