FIELD: metallurgy.
SUBSTANCE: filler of flux cored wire contains the following components, wt %: metal magnesium 30-50, calcium 10-15, alloy of calcium and silicon 30-50, fluor spar up to 5%, total content of metal barium or mixture of metal barium and barium silicide 10-20, and iron is the rest. Total calcium content is 20-50% of filler content.
EFFECT: invention allows increasing fixation efficiency of calcium and magnesium and obtaining steel with high level of mechanical properties and increased purity as to content of non-metallic inclusions, and namely calcium aluminates and sulphides.
