State Key Laboratory... were performed to investigate the effect of slag on oxide inclusions during electroslag remelting(ESR) process. G20CrNi2Mo bearing steel was used as the consumable electrode and remelted using......
. Vanadium-bearing molten iron is oxidized to produce semisteel and vanadium slag; then vanadium is extracted from the vanadium slag by hydrometallurgy methods [1-4,11,12]. Thus, reduction and distribution... of argon gas. At last, the vanadium-bearing pig iron and titanium slag were separated and crushed for subsequent analysis. 2.2 Definition of parameters (1) Vanadium distribution ratio (LV......
precipitation. Key words: vanadium; vanadium slag; roasting; acid leaching; recovery 1 Introduction Vanadium is widely used in various industries, including steel, chemistry, aerospace, and medicine, due to its..., and petroleum residues [4]. Among these, vanadium-bearing slag is the most important source for vanadium, especially in China, where it accounts for approximately 85% of the vanadium production [5,6......
