FIELD: metallurgy.SUBSTANCE: invention relates to ferrous metallurgy, and namely to deoxidising refining mixtures at out-of-furnace treatment of metal in a furnace-ladle unit. Flux consisting of the following components (wt %) and containing CaFis used as material: 23-43 MgO, 25-45 AlO, 10-20 SiO, 5-10 CaO and 2-7 CaF. The mixture contains the following components, wt %: deoxidising agent 10-35, flux 5-20, and lime is the rest.EFFECT: invention allows obtaining steel with sulphur content of not more than 0,005%, increases ladle lining resistance by 10-15% with minimum environmental load.2 cl, 5 tbl, 1 ex |
