Laser measurement system for standardized quality control on round profiles and rebar
Increasing product quality is a major challenge in rolling mills. By means of a laser-based measurement system, the goal of a 100% geometry inspection can be achieved. The CONTOUR CHECK BAR & TUBE scans the steel profile inline and can determine diameter and ovality within seconds. The precise contour measurement also eliminates the need for many sample cuts, thus significantly reducing the cost of quality assurance.
In addition, the CONTOUR CHECK BAR & TUBE has the measuring ranges of 90 mm, 120 mm, and 150 mm, and can be used at material temperatures up to 200 °C. The software application developed by LAP analyzes quality-relevant errors and visualizes the measurement data in real time. Users can also intervene optimally in the ongoing rolling process in accordance with Industry 4.0.
SMART CORE ADVANCED Software
The software visualizes the core dimensions. In addition, the system warns of imminent tolerance violations, which can also be an indicator of a defect on the rollers.
