DEVELOPMENT OF TECHNOLOGY FOR SMELTING VANADIUM FOUNDRY ALLOY BY USING COMPLEX SILICON-ALUMINUM FERRO-ALLOY AS REDUCING AGENT
A conventional technology for smelting vanadium foundry alloy is reviewed in this work. A new technology for technology for smelting vanadium foundry alloy by using complex silicon-aluminum ferro-alloy as reducing agent was developed and studied. A native raw material was used for smelting vanadium foundry alloy. By application of new technology the extraction of vanadium was increased (vanadium extraction ratio – 93–96 %), the efficiency of process was improved. The smelting technology was simplified by absence of additional intermediate operations, such as crushing, refinement.
