Strip Supervisor

Specialized processor of rolling data for evaluation of strip flatness and other quality parameters


StripSupervisor is specialized software designed to collect technological data of cold strip rolling, to process, to display and to store them into a unified database

  • »to monitor technological parameters of rolling process,
  • »to monitor influences of technological parameters on strip flatness,
  • »to eliminate the influence of human factor on the quality of the strip,
  • »to calculate the global quality parameters of rolled production.

For monitoring of strip flatness StripSupervisor requires the rolling mill being equipped with a stressometer. If the rolling mill is equipped with sectional cooling StripSupervisor allows to process information about the intensity of work rolls cooling as well.

StripSupervisor collects, processes as statistically as graphically and archives the following technological information:

  • »strip thickness
    entry and exit thickness along the length of the strip, including statistical characteristics (mean, standard deviation, percentiles, etc.).
  • »stresses and their relation to strip waveness
    longitudinal stresses in selected zones along the strip width. The maximum compressive stress and its comparison with predicted limit stress, which signals the emergence of strip waviness.
  • »changes of the reference curve
    the record of possible operator’s change the reference curve for the stressometer during the rolling process for assessing the impact of the human factor in the process of rolling.
  • »tension forces
    forward and back tension forces during the rolling process, including statistical characteristics (mean, standard deviation, percentiles, etc.).
  • »rolling speed
    entry and exit rolling speeds during the rolling process, including statistical characteristics (mean, standard deviation, percentiles, etc.).
  • »intensity of sectional cooling
    intensity of cooling of particular nozzles of the sectional cooling along strip width during rolling.

Particular records of technological data are supplemented by information about operators in service at the time of recording.

Monitoring of longitudinal tensions in characteristic zones of the strip and its comparison with a limit stress which signals the emergence of waveness

StripSupervisor enables comparison of different technological variables in selected locations on the strip during rolling and putting into the context their effects on the quality of the rolling process. The strip may be viewed either from above or in the selected transverse and longitudinal sections. Statistical data can be further processed in the Microsoft Office.

Benefits:

Main benefits resulting from implementation of the software StripSupervisor are following:

  • »allowing of a quick and conclusive monitoring of the impact of technological parameters on the strip flatness,
  • »allowing of a quick and conclusive monitoring of the impact of technological parameters on the strip flatness,
  • »eliminating of influences of human factor on the quality of strip mainly through more conclusive proving of lack of technological indiscipline of operators in service
