FIELD: ferrous metallurgy, namely out-of-furnace treatment with use of powdered reagents.
SUBSTANCE: wire includes steel envelope and powdered filler containing silicon and calcium, the last is present in filler in the form of silicon-calcium alloy and also as pure calcium. Filler contains in addition aluminum, carbon, phosphorus and iron at next relation of ingredients, mass %: calcium, 38 -66; silicon, 21 - 55; aluminum, no more than 2.0; carbon, no more than 4.0; phosphorus, no more than 0.05, iron, the balance.
EFFECT: enhanced degree of calcium usage, complete globularization of non-metallic inclusions, lowered cost of treatment process, decreased consumption of wire.
