PROVISION FOR IMPROVED RECOVERY OF ALLOY IN MOLTEN STEEL BATH WITH USAGE OF WIRE WITH DEOXIDISER-CONTAINING CORE

摘要

FIELD: metallurgy.SUBSTANCE: invention refers to metallurgy, particularly to adding of wire with filler for alloying of molten steel. The wire comprises a metal shell placed around the mix substance containing FeNb and Si. The metal shell is able of melting after being fed into a molten steel bath. Content of Si in the mix substance amounts to from 5% to 50% of the mix substance in terms of mass or volume. FeNb and Si are powder including particles with the diameter less than 1 mm.EFFECT: usage of the invention provides for the improvement of the additive agent recovery in molten steel.3 cl, 6 dwg
