Experimental Study on Two- step Synthesis of Vanadium- aluminium Alloy

Main factors affecting vanadium-aluminum alloy smelting by two-step process were studied,and the products were analyzed through metallographic inspection.The results show that vanadium yield and apparent quality of the products can be noticeably improved by applying appropriate unit burden heat and superheat degree during tapping in the process of vacuum refining.It is found that the appropriate unit burden heat for aluminum heat smelting process is 3 250 kJ/kg,and the best degree of superheat for vacuum refining is 30 ℃.All the chemical compositions of the vanadium-aluminium alloy so obtained can meet the standards of GfE.
