Beschreibung
Zusammenfassung:	A method for manufacturing an austenitic stainless steel from a nickel laterite ore and a chromite ore includes the steps of determining a nickel content of the nickel laterite ore; processing the nickel laterite ore into a nickel-containing precursor based on the determination; obtaining a molten ferrochrome from the chromite ore; transferring the nickel-containing precursor into a converter, and hot charging the molten ferrochrome into the converter to obtain a molten stainless steel; and charging the molten stainless steel into a continuous casting machine to obtain a stainless steel slab.
