Based on the features of vanadium extracting waste in PanGang, technology ideas are proposed as following: vanadium extracting waste ash is used as coolant in converter, vanadium extracting and vanadium extracting residue is used as slagging material in steelmaking. Influence of slagging material on oxidability of molten steel in converter is analyzed, such as iron and steel consumption, effect of dephosphorization, influence of coolant on semisteel quality after extracting vanadium, and quality of vanadium slag. New way to utilize the waste is developed. Recycling the vanadium extracting waste in PanGang, mitigate the environmental pressure.

Direct alloying with molybdenum oxides has been regarded in years; the main addition methods are adding to the bottom of electric arc furnace (EAF) with scrap, adding to the ladle during the converter tapping and mixing molybdenum oxide, lime and reductant to prepare pellet added to basic oxygen furnace (BOF). In this paper, a new method for direct alloying with molybdenum trioxide is proposed, adding molybdenum trioxide molten steel by feeding wire method in ladle furnace (LF) refining process. The feasibility of molybdenum oxide reduction, the influence rules of bottom-blown on liquid steel fluidity and the yield of molybdenum by feeding wire method were analyzed. Results show that molybdenum oxide can be reduced by [Al], [Si], [C], and even [Fe] in molten steel. Bottom blowing position has a significant influence on the flow of molten steel when the permeable brick is located in 1/2 radius. The yields of Mo are higher than 97% for the experiments with feed wire method, the implementation of direct alloying with molybdenum trioxide by feed wire method works even better than that uses of ferromolybdenum in the traditional process.
