NTIS: PB 248 772 Available for Reference At Bureau Libraries :41 pages
Six major trends that have had and are continuing to have major effects on the use and supplies of pig iron and scrap in the United States are (1) gradual replacement of the basic open hearth furnace (oh) by the basic oxygen furnace (bof); (2) use of the electric furnaces for the production of plain-carbon steels, a trend that is closely related to the first; (3) United States changing from being a net exporter to a net importer of steel; (4) replacement of ingot casting by strand casting; (5) increased exportation of scrap; and (6) the lack of growth of the capacity of the U.S. steel industry to produce pig iron in the last 5 to 8 years. This report gives an analysis of the relationships between these trends and the use of processes for the production of raw steel in solidified form.
