FIELD: metallurgy.
SUBSTANCE: invention concerns metallurgy field and can be used in steelmaking for deoxidation, desulphurizing and retrofitting of steel melt. Material for out-furnace treatment of steel melt contains silicon in the form of ferrosilicium or in the form of ferrosilicium and metal silicon mixture and calcium in the form of alloy with silicon or in the form of calcium in metal phase and alloy with silicon mixture at further ratio of elements, wt %: calcium 20-56; silicon 40-60; iron 1-25. Mentioned material can be used as filler of flux cored wire, at that quantity of filler in flux cored wire is 45-65 wt %, and particle size of flux cored wire filler material doesn't exceed 3 mm.
EFFECT: rising of calcium fixation, reduction of calcium vapor partial pressure at melt treatment temperatures.
