摘要：

Production of low carbon stainless steels implies specific and complex refining processes, starting with melting and refining in EAF, and proceeding further with refining under vacuum (VOD) or with Ar dilution (AOD). Increasing quality requirements for the most stringent specifications resulted in more specific refining processes: ESR remelting (cleanliness), deep VOD (ultralow C&N content), PESR (high nitrogen content), powder metallurgy. Refining of chromium containing hot metal was performed in adapted converter used for refining non-alloyed hot metal (Kaldo, QBOP) for carbon steels production. EAF melting and AOD refining is nowadays the most widespread route of production of stainless steel, however some integrated steel plants for low alloyed flat products (blast furnace hot metal, converter, continuous casting, continuous strip rolling) designed specific routes for stainless steels production.
