ISEND: Surface Quality and Geometry Control in a Single System

The steel industry is facing unprecedented challenges. Emission regulations, high energy costs, and increasingly demanding industry requirements are just a few examples. As a result, rolling mills must find more efficient ways to produce in order to meet these challenges.

Traditionally, rolling mills are equipped with non-destructive testing systems for surface quality control, along with additional systems for geometry control. This setup requires a lot of space on the line—a limited resource in many cases—and also demands multiple service and maintenance tasks at different time intervals.

This is where ISEND’s EDDYeyes system can revolutionize the sector. The EDDYeyes system is currently in use at several rolling mills. It combines the power of Eddy Currents with Computer Vision and Artificial Intelligence to detect surface defects in real time, while also providing images of the defects and automatically classifying them.

Now, thanks to high-speed cameras in the vision module and AI algorithms, the EDDYeyes PRO system can also function as a profilometer, delivering the same level of precision as traditional laser profilometers. High-speed cameras offer several advantages over laser-based systems, such as reduced maintenance times and longer service life.

This new feature transforms EDDYeyes PRO into a complete solution for quality and process control, offering a high level of oversight over various product and process variables. The information provided by the system allows operators to make real-time decisions regarding line issues, reducing downtime and improving process efficiency.

Benefits of the EDDYeyes PRO System:

• Real-time geometry control
• Defect maps for 100% of production
• Indications of defect depth
• Automatic defect classification
• Early detection of broken rolls and guides
• Single system → Optimized maintenance
• Real-time information for decision-making
