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.
