Historical Operating Cost Comparison for North American Iron and Steelmaking Routes

摘要

Historical iron and steelmaking operating costs were calculated for the last ten years for American steelmakers using published raw materials prices and Hatch's operating cost models. Over the last few years, North America has seen the gradual closing of a number of integrated facilities or blast furnaces and additional electric arc furnace (EAF) steelmaking capacity brought on-line. Two Southern USA direct reduced iron (DRI) facilities have been built to take advantage of low-cost natural gas.
