Process for producing stainless steel using direct reduction furnaces for ferrochrome and ferronickel on the primary side of a converter

摘要

In order to allow a significant reduction of the steel production cost when producing stainless steel with the alloying elements chromium and nickel, according to the invention, it is proposed to perform the intermediate production of ferrochrimium and ferronickel in two separate direct reduction processes based on low-cost chromium ore and nickel ore in two SAF (3, 4) arranged in parallel on the primary side of a processing converter (6).
