FIELD: metallurgy.
SUBSTANCE: procedure consists in melting charge in electric furnace, in heating iron melt in it to temperature 1490-1510°C and in modification of produced melt in ladle with mixture containing complex addition alloy FSMg7 containing REM (rare earth metals) 0.3-1.0 %, magnesium 6.5-8.5 %, at amount of 0.2-0.5 % and 22 % silicobarium SIBAR22 at amount 1.5-2.0 % of weight of treated iron melt.
EFFECT: high mechanical properties of iron without formation of chills in casts.
