FIELD: metallurgy, in particular complex alloy for deoxidation and doping of steel and cast iron.
SUBSTANCE: claimed addition alloy contains (mass %): iron 25-50; aluminum and silicium 75-50 in Al/Si ratio of (1:1)-(3:2). Claimed Al/Si ratio is the most preferable to produce high quality ingots due to more deep steel deoxidation with aluminum and sufficient steel doping with silicium.
EFFECT: increased coefficient of aluminum utilization; method for producing of silicon steel with improved efficiency.
