METHOD FOR MICROALLOYING STEEL WITH VANADIUM

摘要

FIELD: ferrous metallurgy. SUBSTANCE: before pouring cast iron naturally-alloyed with vanadium into low-carbon product, it is mixed with liquid conversion cast iron, maintaining the relation of carbon introduced with it to vanadium of naturally-alloyed cast iron within 0.5-7.0 and the temperature of cast iron mixture before pouring in, within 0.8-0.9 of the temperature of low-carbon product. EFFECT: stabilization of vanadium content in steel, reduction of total contamination with its inclusions and sorting ingots for surface defects. 3 tbl
