FIELD: metallurgy.
SUBSTANCE: invention relates to the ferrous metallurgy, particularly to out-furnace treatment of steel by powder-like reagents. Wire consists of steel envelope and filler containing calcium, barium, magnesium, silicon, and aluminium at following correlation of components, wt %: calcium 5-18; barium 5-15; magnesium 3-9; silicon 25-45; aluminium - the rest, herewith calcium, barium and magnesium in filler are in the form of silicides.
EFFECT: increasing of temperature-time interval of elements influence of modifier on process of refinement and modification of steel.
