Optimal Residual Stress Control – ORSC

Situation:

  • Trend in product development where higher quality standards with tighter material property tolerances are demanded by clients.
  • Quality problems coupled to residual stresses.
  • Traditional control approaches are working insufficiently.

Solution:

  • Development of a new “residual-stress-based” control concept applying
    • online stress state measurement prototype for strip material,
    • improved modelling approaches able to describe material behavior under loading.

Operational benefit:

  • New “residual-stress-based” control concept for improved product quality regarding residual stress state and corresponding flatness
  • Prediction and evaluation of residual stresses
  • Basic understanding for residual stress generating mechanisms and their sources
  • Knowledge about the interdependencies of internal stress evolution and their corresponding warpage/distortion of strip products
  • Identification of quality relevant process and facility specific influencing parameters
