How Steel is Made
To produce steel, facilities use one of two processes, which utilize
different raw materials and technologies. These two main
steelmaking processes are the Basic Oxygen Furnace (BOF) and the
Electric Arc Furnace (EOF).
The Basic Oxygen Furnace process uses 25 to 35 percent old steel to
make new steel. BOFs make up approximately 40 percent of today's
steelmaking in the U.S.
The Electric Arc Furnace process uses virtually 100 percent old
steel to make new steel. EAFs make up approximately 60 percent of
today's steelmaking in the U.S.
Below are various steel processing operations that are used in the
BOF and EAF processes.
