SteelmakingWikipedia
Modern steelmaking processes can be divided into two categories primary and secondary. Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace.. Secondary steelmaking involves refining of the crude steel before casting and the various
