Influence of Vanadium Extraction Converter Process Optimization on Vanadium Extraction Effect

In view of the problem of low bottom-blowing stirring intensity and easy blockage in the use of capillary bricks, the bottom-blowing gas supply element of circular seam was used. The results of water model experiments shows that the suitable bottom-blowing element was arranged on the circumference 0...

description In view of the problem of low bottom-blowing stirring intensity and easy blockage in the use of capillary bricks, the bottom-blowing gas supply element of circular seam was used. The results of water model experiments shows that the suitable bottom-blowing element was arranged on the circumference 0.45D away from the center of the furnace bottom (where D is the diameter of the converter bottom). The best blowing process parameters for vanadium extraction from hot metal were are obtained in different periods. The industrial test results shows that the average values of vanadium content in semi-steel and metallic iron content in vanadium slag were 0.033 wt% and 22.39 wt%, respectively, after process optimization, which were 0.003 wt% and 5.25 wt% lower than those before process optimization. The average value of vanadium oxide content in vanadium slag was 18.54 wt%, an increase of 0.2 wt% compared with the one before process optimization. This shows that after the process was optimized, the kinetic conditions of the molten bath were improved, and the vanadium oxide reaction was more sufficient. An additional 5210 tons of vanadium slag could be produced each year, and better economic benefits could be obtained.
