Method for preparing low-vanadium alloy material from vanadium-containing converter steel slag

The invention discloses a method for preparing a low-vanadium alloy material from vanadium-containing converter steel slag, and relates to the field of comprehensive utilization of the vanadium-containing steel slag. According to the method, the vanadium-containing converter steel slag is subjected to graded magnetic separation, two different materials are obtained, two pellets with different components are prepared, layered placement is achieved during charging, the air permeability of the materials is improved, and the low-vanadium alloy material is prepared. And splashing and big boiling caused by the fact that a large amount of CO and CO2 are generated in the melt reduction process are greatly eliminated, and safety is enhanced. And through layered pellet arrangement, liquid-phase reduction, pellet internal reduction and pellet external reduction are carried out at the same time, and energy consumption is greatly reduced. The whole process is low in raw material cost and convenient to purchase; and the yi
