Objective
Inclusions cleanliness remains an important factor of steel quality. Present non-destructive techniques (NDT) are not sufficient to assess it. Lack of inclusions cleanliness in steels for packaging applications is also a large source of class lowering and disputes with customers. This project aims at improving, on one hand ultrasound and micro-radiography combined with data fusion techniques and numerical signal processing for the inspection of as-cast samples and on the other hand magnetic stray flux method using giant magneto resistive heads for the on-line inspection of cold rolled strips. Validation and comparison trials will be performed on as-cast and rolled samples. The main impacts will be the reduction of off-cut, scarfing and class lowering and an increase of the trade acceptance of steel.
