| Summary: | This paper focuses on oxidationS behavior of C, Si, Mn, P, Nb in Nb-bearing hot metal during bottom-blowing oxygen in a vacuum-induction furnace. This blowing process was carried out separately with and without slag at the flow rate of 0,4 m<sup>2</sup>/min to 0,6 m<sup>2</sup>/min. The results show that niobium is massively removed from the hot metal while silicon content in hot metal is decreased to lower than 0,01wt. % with adding slag , P content keeps unchanged, and sulfur content is decreased in hot metal at the beginning of blowing stage while it increased in hot metal with the extension of smelting time. |
