Abstract

FIELD: metallurgy. SUBSTANCE: introduction into deoxidized steel smelt of powder oxide manganese-containing material, reducing agents, and fusion agent is performed in one step using a mixture of oxide manganese-containing material (66-75 wt %) with fluorospar (1-5 wt %), and a material selected from the group including aluminium, ferrosilicium, and silicocalcium (the balance). The mixture is introduced into the smelt in the form of a shell powder wire in amount 20-55 Nkg per 1 t of steel where N (in wt %) is required increment in manganese content in final steel. EFFECT: simplified process. 6 cl, 2 tbl

Claims (1)

The inventive introduction of powdered oxide manganese-containing material, reducing agents and flux into the melt of deoxidized steel is carried out simultaneously, in the form of a mixture of oxide manganese-containing material with fluorspar and a material selected from the group: aluminum, ferrosilicon and silicocalcium, in the ratio of components in the mixture, wt.% : oxide manganese-containing material 66 - 75, fluorspar 1 - 5, a material selected from the group: aluminum, ferrosilicon, silicocalcium, - the rest, and the mixture in the form of a filler about lochkovo cored wire is introduced into the melt in an amount (22 - 55) • N kg / t steel, where N - the desired increase of manganese content in the finished steel wt.%.
