Length of Steel Sheets in Refinement Facilities

Exact length measurement of steel sheet in scissors / refinement lines

The length measurement of a steel sheet with oiled surface, over embraced rollers is possible only with limited accuracy. Refinement systems and shears (longitudinal and cross sections) are therefore better equipped with non-contact μSPEED systems. μSPEED systems can cope with faint as well as high-gloss surfaces.

Typical application data:

  • Path Velocity: typically up to 1,500 m / min
  • Measurement accuracy with tactile measuring equipment or via drive: typically 0.5 – 3%
  • Measurement accuracy with non-contact length measurement μSPEED: typical: 0.03%
  • Amortization: 1 month, direct encoder replacement, no other modifications needed

Material examples:

  • Steel sheet, tinplate, packaging steel, sheet metal
  • Stainless steel sheet, galvanized sheet metal, rolled sheet

Machines equipped with non-contact length measurement:

  • Rolling plants, rolling mills, rolling trains, rolling stands
  • Refinement plants, scissors, cross cutter, lengthwise cutter
  • reel, looper, winding machines, rewinder
  • Monitoring the roller table drive
