| Technical know-hows regarding decarburization and V oxidization during BOF vanadium recovery at Pangang were worked out, and operating process was optimized accordingly. Remarkable results were achieved: V oxidization≥86%; V recovery≥78%; residual vanadium in blown metal ≤0.06%, carbon content in blown metal≥3.2%, target temperature of blown metal 1360～1410℃, blown metal yield≥90%. V-slag quality indices reached the criteria for the first class V-slag according to the YB/T008-92 and CaO content≤2.0%. |
