Abstract [en]

The behavior of MnS inclusions during flat hot rolling of steel has been studied. Experiments were carried out in a four-high mill. The workpiece was up to a nominal reduction in height of 85% in four passes, at rolling temperatures of 700-1200degreesC with interpass reheating. The relative plasticity and orientation of inclusions were quantitatively assessed by means of an image-processing tool. Finite element analyses were performed in order to scrutinize the concept of 'relative plasticity', which is based on dimensional change of the inclusion, Furthermore, inclusion reorientation is discussed.
