Innovative non-contact, non-destructive sensors for automatic detection of surface and internal defects in hot continuously cast products

Objective

The quality of slabs is the basis of good quality for all other steel products in the downstream production process. The automatic on-line detection and logging of surface, subsurface and internal defects for the controlling and optimization of the scarfing process and for use during continuous casting is important. An EMAT/EMAT Phased-Array-System and a LASER/EMAT-System will be developed to detect these defects.

The Conoscopic-Holography-System can currently only find repetitive longitudinal defects and this system needs to be further developed. The control of downstream processes for tracing steel through the mill will be also bringing big advantages to the steel industry.
