Medium-carbon ferrochrome is also a product of interest in the foundry industry and in steelmaking plants where refining capacity is limited but low silicon content is desired. Most of the medium-carbon FeCr is produced by the oxygen-converter method. It is based on carbon removal from liquid high-carbon ferrochrome (8% to 9% C, 0.3% to 0.5% Si, 0.04% P) with gaseous oxygen blowing (Karnouhov ...
