FIELD: ferrous metallurgy, in particular, processing of melts beyond furnace by means of powdered reactants.
SUBSTANCE: wire includes steel sheathing and powdered filler comprising calcium and silicon. Calcium content in filler is 36-56 wt%. Calcium and silicon ratio is (0.6-1.3):1. Ratio of calcium content in filler and filler content in wire is 0.7-1.2. Calcium may be available in filler in the form of calcium and silicon alloy. 10-50% of pure calcium may be available in filler. Components of wire are used in the following ratio, wt%: powdered filler 45-61; steel sheathing 39-55.
EFFECT: increased extent of usage of calcium, complete globulization of non-metallic inclusions and reduced consumption of wire.
