GASIFIION AND THE MIDREX? DIRECT REDUCTION …
2016-1-25 · There are two basic methods for making liquid iron: (1) a coal based process consisting of coke ovens, a blast furnace, and a basic oxygen furnace, and (2) a process in which scrap steel and/or DRI is melted by an electric current in an electric arc furnace (EAF). A plant using the electricity based process is called a mini-mill.
Clean Ironmaking and Steelmaking Processes: Efficient
Ironmaking and steelmaking are some of the largest emitters of carbon dioxide (over 2Gt per year) and have some of the highest energy demand (25 EJ per year) among all industries; to help mitigate this problem, the book examines how changes can be made in energy efficiency, including energy consumption optimization, online monitoring, and
