抄録

We have observed of ferro-vanadium, by hot nitric acid extraction method, the form of non-metallic inclusions, relation between alloying elements and inclusions, and gas content. The results obtained were as follows.<BR>(1) Non-metallic inclusion are in close connection with Al content: Inclusions are 0.5 to 0.2% and 0.05% respectively to the ranges of 0.19 to 1% and 1.4% to 2.5% of Al contents. The latter being lowest inclusions increase again incase of over 2.5% of Al content.<BR>(2) Non-metallic inclusions are mainly B-Al2O3, the type of which are transparent board, dendrite, granular free crystal and spheric crystal.<BR>(3) Oxygen content in ferro-vanadium is nearly corresponding to the one computed in inclusions and has the same tendency as inclusions in relation to Al content.
