Abstract
Experimental research was carried out to optimize the technology of industrial ferrovanadium production by the electroaluminothermic method under electroslag melting conditions using chemically enriched vanadium-containing industrial waste. The pilot melts were performed using a modified industrial OV-1901 unit with a direct current power source. During the melting process, vanadium oxides are reduced directly in the slag layer with controlled supply of additional electric energy, regulating the intensity of the reduction process and enabling the production of a ferroalloy with a specified vanadium content. During the experiments, the charge composition and process parameters were varied to determine the basic process conditions that ensure stable production of FeV50 and FeV60 ferroalloy grades intended for manufacturing of welding electrodes. The vanadium recovery rate into the alloy during pilot melts was 85…90 %. With a direct current source, the optimal configuration is to connect the power supply with the main electrode at a positive potential. The influence of the duration of holding the slag pool under current after complete melting of the charge on the residual vanadium oxide content in the slag and the degree of vanadium recovery into the alloy was determined. With increased holding time, the residual V2O5 content in the slag decreased from 21.57 % without holding to 4.36 % after 20 minutes of holding. The results obtained confirm the feasibility of using technogenic waste for ferrovanadium production and indicate the prospects for further optimization of technological parameters to increase vanadium recovery efficiency and to improve the economic indicators of the process. 22 Ref., 3 Tabl., 3 Fig.
