Based on the reduction law of calcium vanadate, which was explored in the laboratory, the experiments were carried out during direct alloying with calcium vanadate in a high‐frequency induction furnace with a capacity of 25 kg. The average recovery ratio of vanadium was 83.4 %. The tests were also carried out for direct alloying with a briquette of calcium vanadate in a 0.51 electric arc furnace and with cold‐bound pellets of calcium vanadate in a ladle to smelt the low alloy steel with mass contents of about 0.1 % vanadium. The recovery ratios of vanadium were 89.9 % and 86.0 %, respectively.
