The size,number and morphology of inclusions in IF steel produced by BOF-RH-CC process were analyzed by scanning electronic microscopy(SEM),energy dispersive X-ray spectroscopy(EDS),and metal original position analysis(OPA).The results show that inclusions distribute uniformly along the width direction; the number of inclusions in head slab is much larger than those in other slabs;there is an inclusion accumulation zone around 20 mm away from the inner arc surface where the inclusion content is much higher than those in other positions.The sizes of the inclusions are mainly in 0~5 μm and there is a small amount of inclusions larger than 10 μm gathering in the areas around 20 mm away from the inner arc surfaces of slabs.
