FIELD: metallurgy.
SUBSTANCE: nitrogen containing alloy is used for treatment of steel melt in ladle with nitrogen containing materials. Alloy corresponds to composite alloying material on base of silicon nitride with ferro-silicide binding consisting of silicon, iron silicide and/or iron at the following weight ratio of components: ferro-silicide binding 20-50 %, silicon nitride - the rest; also nitrogen containing alloy has porosity 20-60 %.
EFFECT: stable specified concentration of nitrogen in steel without increase of process duration.
