Energy requirements for iron and steelmaking.

Contemporary trends in energy consumption were determined. The time period 1964-70 was selected for analysis because shipments from U.S. producers were remarkably stable despite great changes in market size and in technology. Major changes were observed in requirements for 14 of the 20 principal minerals. Eleven of the major changes were fuels; they ranged from a decline of fuel oil consumption by 45 pct to increases in bituminous coal of 8 pct. Improvements in the technology of the various processes exerted only minor effects on aggregate usage of mineral raw materials and energy. The historic ratio of pig iron to purchased scrap used for steelmaking (73:27) connotes a 3-to-1 sharing of raw steel production between the basic oxygen furnace and electric-arc furnace methods.
