摘要

To improve the vanadium extraction rate, the iron ore powder was used to be injected into the molten bath by side-blowing. Both simulation numerical and water experiment model for analyzing the behaviors of molten bath flow field had been developed to investigate the mixing time, velocity profile and dead-zone volume of molten steel under various injection arrangements and gas flow rates. The result showed that the mixing time would reduce, with increasing the distance between side-blowing nozzle and molten bathe surface. Moreover, although the kinetic energy would be removed by the mutual influenced between bottom-blow bubbles and the side-blowing jet at a certain content, the stirring effect of molten bath is still improved by the side-blowing jet. Based on the result of simulation, an injection arrangement was used in the 150 t vanadium extraction converter. Based on the results, the vanadium content of semi-steel and T. Fe in the slag with side-blowing arrangement is 0.033% and 34.1%, respectively. And the vanadium content of semi-steel and T. Fe in the slag with side-blowing arrangement is 0.044% and 32.1%, respectively.
