MEERgauge® is a sophisticated laser measuring system developed by SMS Group, designed for precise measurement and control in the steel production process, particularly for bars, wire rods, and tubes. This advanced technology is integral to enhancing operational efficiency and product quality in the metallurgical industry. MEERgauge® employs advanced laser light-section technology, enabling true shape size measurement and online surface defect detection. It can measure up to 99% of the bar surface with high precision, providing synchronous, contact-free measurements over the entire cross-section of products. The system operates at a scanning rate of up to 15,000 scans per second, allowing for real-time adjustments and quality control during production. 

Customer challenges addressed

  • In-line autonomous laser measurement system used for hot- and cold- rolled long products
  • High measurement data density
  • Short exposure time and absolute synchronization of the measuring probes
  • Measuring equipment in the immediate vicinity of the roll stands
  • Direct transfer of measured values to the mill stand control system (mill stand control)
  • Time and cost benefits from direct production control
  • Product dimensions control using laser triangulation method for profile measurement
  • Sensors provide non-contact measurement by capturing up to 1,000 contours per second for rounds and 500 contours per second for other profiles
