Effectiveness of Alloying Steel with Vanadium from Cored Wire

Abstract

An analysis is made of the distribution and assimilation of vanadium in finished steel. It is shown that the character of assimilation of vanadium is unstable when lump ferrovanadium is used. Given the same consumption of ferrovanadium per heat, the scatter of vanadium content is 0.007–0.18% (abs.) or 20.6–37.5% (rel.). The alloying of steel by cored wire filled with a vanadium-aluminum master alloy (72.9% V and ∼26.5% Al) results in a consistently high level of vanadium assimilation – 98.7%. The minimum level of assimilation in this case is 90.1%.
