PolySLAG

Slag detection system for remote tapping

System description

PolySLAG is an advanced vision-based system designed to optimize the tapping process by accurately detecting the transition between steel and slag in real time. The solution combines a thermal camera and a high-resolution color camera to continuously monitor the tapping stream, generating an intuitive visual interface that clearly distinguishes steel (green) from slag (red) while displaying the real-time percentage of each material.
The system records images and complete tapping cycles, providing valuable production data and enabling the automatic management of the tapping process. By improving tapping accuracy, PolySLAG helps reduce slag carryover, increase product quality, enhance operator safety through remote monitoring, and deliver more reliable and efficient steelmaking operations.
