Oxidations behavior of C, Si, Mn, P, Nb in Nb-bearing hot metal by bottom blowing oxygen

Oxidations behavior of C, Si, Mn, P, Nb in Nb-bearing hot metal by bottom blowing oxygen

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&g...
