Alloying of vanadium steel even in small quantities up to 0.1% V significantly increases the performance properties of steel. However, the schemes of smelting alloyed with vanadium steels have a number of problems. For example, when using metallized vanadium-containing pellets, their proportion can be up to 30-50%. and to increase the mechanical strength of such pellets, the process of their metallization in mine furnaces is carried out at temperatures 150-200 0C higher than the temperature during the metallization processes of pellets from ordinary ores that do not contain titanium. In addition, for the process of metallization into oxidized pellets from titanium magnetite ores, it is necessary to add lime to increase their mechanical strength, but with an increase in basicity, reduces the strength of the metallized pellets obtained. These disadvantages complicate and increase the cost of metallized vanadium pellets, lead to a partial loss of their strength, which in turn increases the cost obtained in electric arc furnaces alloyed with vanadium steel .. When using vanadium slag in an amount of 3-3.5% of the weight of the metal and the degree of absorption of vanadium by metal, 80-90% is provided
