PRODUCTION OF AUSTENITE STAINLESS STEEL FROM LATERITE NICKEL ORE AND CHROMITE ORE Russian patent published in 2015 - IPC C21C5/28 C22B23/00 C22B34/32 C22B3/04 

Abstract RU 2539280 C1

FIELD: metallurgy.

SUBSTANCE: proposed process comprises definition of nickel content in laterite nickel ore. Then, said ore is processed to nickel-bearing precursor proceeding from nickel content definition to produce fused ferrochromium from chromite ore. Then, nickel-bearing precursor is fed while fused ferrochromium is loaded into converter to get fused stainless steel. Then, produced stainless austenite steel is fed to continuous casting machine to get steel slab.

EFFECT: higher efficiency of this process.
