FIELD: metallurgy. ^ SUBSTANCE: invention relates to metallurgy immediately dealing with extrafurnace refinement and modification of steel, cast iron and non-ferrous alloys. The modifier is represented by a dispersion product resulting from conversion of by-products of the ANP mineral fertiliser production, its chemical composition (wt %) being as follows: calcium carbonate - 90-94%; strontium carbonate - 2-5%; impurities represented by magnesium and barium carbonates and silica, titanium, aluminium and ferric oxides - balance. ^ EFFECT: invention provides for enhancement of mechanical properties and microstructural improvement of the alloys processed. ^ 8 tbl, 1 ex |
