METHOD OF PRODUCING OF VANADIUM SLAG AND STEEL ALLOYED WITH VANADIUM

摘要

1. A process for the production of vanadium slag and vanadium alloy steel comprising vanadium redistribution of iron in the basic oxygen furnace slag and vanadium on interm comprising pouring vanadium pig iron in the converter, blowing it with oxygen and coolant, repartition the precursor steel comprising filling the converter coolers fill precursor, ignition and purge oxygen melting, slag additive unit dose during the purge, tapping into the ladle, it carburization, deoxidizing, alloying e and finishing, characterized in that the coolers are used as granulated iron vanadium with a fraction of 5-15 mm and scale, their total flow rate is 90-235 kg / t of pig iron. ! 2. A method according to claim 1, characterized in that in a first process stage as the coolers sits 20-200 kg / t of pig iron - iron and vanadium granular 70-0 kg / t of pig iron - scale, and in a second process stage as the coolers a seat 20-60 kg / t of metal - vanadium granular iron.
