METHOD FOR SMELTING OF FERROALUMINUM Russian patent published in 2004 - IPC

Abstract RU 2241777 C1

FIELD: metallurgy, in particular alloy for deoxidation and doping of steel and cast iron.

SUBSTANCE: claimed method includes simultaneous smelting of steel batch and aluminum recrement in electric furnace at 900-1400⁰C in carbon-containing reduced medium. Steel junk and/or iron dross with iron oxide content ≥50 mass % is used as the batch, and aluminum content in aluminum recrement is ≥10 mass %. Invention affords the ability to simplify ferroaluminium production.

EFFECT: alloy with more precise chemical composition; decreased aluminum melting loss up to 1-2 %.
