Objectif
Development of high performance steel grades conducts to more and more severe cleanliness / inclusions populations requirements. Steelmakers have a real need to control during steelmaking inclusions populations at the liquid state. It was established that inclusions present in liquid steel samples are not often representative of inclusions actually present in the liquid - moreover solid steel.
In this way wrong cleanliness evaluations conduct to quality troubles and customers' claims. The benefits estimated for total European steels production is 32M/year. So, proposal's aims are to determine the most representative liquid steel sampling parameters to optimise the correlative inclusions populations' assessment.
