Future steelmaking plant with minimized energy consumption and waste evolution

A view is presented on future BF‐BOF type and EF type steelmaking plants. The former and the latter include, respectively, rationalized process steps for a mass production and small lot production of quality steels at reduced costs. Integration of the 2 types of plants is discussed for better synergy effects. Emphasis is placed on minimizing the consumption of primary energy and evolution of wastes such as dust, slag and gases, with a consideration given for maximized utilization of the wastes. Metallurgical key issues for future R & D to achieve improved productivity and wastes evolution are also suggested.
