Beschreibung
Zusammenfassung:	The invention relates to a process for manufacturing stainless steel by using high-phosphorus nickel-chromium pig iron, which comprises the steps of charging, electrification, oxygen blowing, flushing, refining and the like. By the process provided by the invention, high-phosphorus nickel-chromium pig iron is dephosphorized in an electric furnace, stainless steel is produced by smelting, the high-phosphorus nickel-chromium pig iron with low cost is adopted as a raw material, the manufacturing cost of each ton of stainless steel can be lowered by about 200 dollars, the use field of the raw material of the stainless steel can also be further expanded, and the nickel-chromium pig iron with high phosphorus content can be applied to the smelting production of the stainless steel in a large scale.
