Abstract

Spheroidizing treatment is an important step in the production of ductile iron, in this paper, with the different amount of nodulizer, the morphology and composition of inclusions in molten iron, spheroidized samples and test blocks were studied by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS), and the inclusions were extracted from the three kinds of samples by electrolytic extraction, XRD analysis was carried out to quantitatively study the effect of residual magnesium content on graphite morphology and spheroidizing rate. The results showed that the amount of inclusions in the molten iron sample was relatively small, whether the amounts in spheroidized samples and test blocks were rather more, and when addition of nodularizer increased from 1.1% to 1.3%, the total content of inclusions in the castings increased from 0.83% to 0.93%.
