EdgeMon

edgemonThe Challenge:

  • Strip breakage in CRM
  • Defects due to bad trimming results in processing lines
  • Set-up time of trimming share after maintenance
  • Time-consuming inspection by Operator

The Solution:

  • Simultaneous monitoring of both strip edge surfaces after the side trimmer
  • Automatic detection of several side trimming defects: alarm at knife breakouts, warning at general bad quality
  • 100% inspection, immediate evaluation

Customer Benefit:

  • Fast adjustment of new knifes
  • Optimized life duration of knifes
  • Less scrap by recognition of breakouts
  • Inline check of knife settings

Short Description:

2D-characteriszation of side-trimming process strip edge visualization, calculation of cut-to-break ratio, knife-breakout detection

Intelligent Dummy Bar

The Challenge:

  • Knowing condition of strand guidance with minimum measurement afford
  • Continuous monitoring of strand

The Solution:

  • Mounted in the dummy bar chain
  • fully automatic data transfer
  • Unique tool that measures roll Torque

Customer Benefit:

  • Continuous monitoring of strand conditions
  • Torque measurements prevents scratches in slabs and increases time between maintenance of segments
  • Optimum roll life time (Minimum maintenance costs for best slab quality)

Short Description:

Inline strand condition monitoring device for roll gap,and roll torque

Chatter Block Monitoring

The Challenge:

  • Strip breakage due to third octave chatter
  • Surface defects (chatter marks) due to fifth octave chatter
  • Higher abrasion at bearings and rolls due to chatter vibrations

The Solution:

  • Inline measurement of the vibration status of each rolling mill stand
  • Evaluation of 3rd and 5th octave chatter, detection of work- and backup roll defects
  • Signal for automatic line speed reduction in case of 3rd octave chatter

Customer Benefit:

  • Automatic reduction of line speed at 3rd or 5th octave chatter
  • Preventing strip breakage (3rd octave chatter)
  • Increased product quality due to monitoring of 5th octave chatter and roll defects

Short Description:
Chatter monitoring of rolling mills including online visualization of chatter conditions, automatic line speed control and roller stroke detection.
