Effect of Ti and Zr Deoxidation Process on the Inclusions in Low Carbon Steel

Abstract:

The35kg ingot was refined with vacuum induction furnace by means of three various deoxidationprocesses in laboratory. From the steel-making point of view, effect of deoxidationprocess on inclusions and was analyzed. The fraction, size and distribution ofinclusions were studied with scanning electron microscope (SEM)and energy dispersive spectrometer (EDS) in three various deoxidation processessteel . The results showed that the volume fraction of inclusions was thelargest in Ti/Zr deoxidation process and the inclusions distributed uniformly. Itwas found that the amount of fine inclusions size in the range of 0.5~1.5 μmwas the largest atTi/Zr deoxidation process. The fraction of inclusions decreased with holdingtime increasing during alloying in present study.
