Paper Abstract

An automatic detection system of hot slab subsurface inclusions has been developed for the purpose of eliminating demerits in the conventional flame observation method. The system takes images of the melting area while scarfing the surface of hot slab, and auto-matically detects sparks emitted from defects. The special designed nozzles can perform fin-free scarfing. The system can also classify hot slabs into grades in a way similar to an expert inspector.
