MIDREX Processes - KOBELCO

2011-1-6  MIDREX direct reduction ironmaking (hereinafter referred to as the MIDREX process) reduces iron ore using natural gas. The original process was developed by the Midland-Ross Co., which later became MIDREX Technologies, Inc. (hereinafter referred to as MIDREX Technologies), a wholly owned subsidary of Kobe Steel. A pilot plant was built in Toledo, Ohio in 1967. The first commercial plant, having a production capacity of 150 thousand tonnes/year, was built in Portland, Oregon, in 1969. The process was immature in 1978, when Kobe Steel began the construction of a plant with a production capacity of 400 thousand tonnes/year in the State of Qatar. Kobe Steel significantly modified the design, exploiting the company's technologies developed through blast furnace operation, and stabilized the then new process. On the other hand, MIDREX Technologies
