Abstract：Through water simulation experiment, gas and powder mixture were thought as a larger density of gas phase flow in powder injection vanadium extraction process. The electrical conductivity were measured to compare mixing time of different powder injection flow and position experiments for studying stirring effect and impacting characteristics of injecting powder in the 150t vanadium extraction converter. It is found that it is easy to block the injection nozzle by bottom injecting powder. When the nozzle is in the side part of 30 degrees and 300mm lower than pool surface, the mixing time is only 54.5 seconds. So the position which is symmetric with side blowing place in 30 degrees about axis A should be the best powder injection position. It is beneficial to strengthen stirring ability of vanadium extraction molten pool and promote vanadium extraction reaction, which will provide the theoretical support for the realization of high efficiency vanadium extraction by powder injection in converter.
