Converter Process - an overview | ScienceDirect Topics

In the steelmaking process, the carbon problem is linked to chromium: when carbon is oxidized in the converter or other process also, e.g., electric furnace, Cr starts to oxidize. This means that in old times stainless steel production could not be done in a converter but electric furnace was used to melt stainless and carbon steel scrap.
