Measuring System for Semifinished Products, such as T-Beams and U-Irons

The profile measurement system is state-of-the art compact device, using up-to-date high-speed cameras, light section sensors and powerful laser line sensors. It is installed in an O-frame for being protected against high ambient temperatures.

Animation for visualizing the profile measuring of U-ironsThe system is designed for detecting following materials:

  • Supporter IPE 120 - IPE600
  • HE80 – HE400
  • U-irons U80 – U450

Following process requirements are considered:

  • Permitted rolling speed up to max. 10 m/s
  • Rolled bar length up to 100 m
  • Staff aftermath 42 s minimum
  • Material temperature > 850 °C to < 1,150 °C
  • Width of roller table 1000 mm
