Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in 2001 to 225 kg in 2013.

Steel is typically made in an integrated steel mill (ISM) (see Fig. 16.1), located close to a large river or a deep sea harbour, which typically receives coal and iron ore (oxide, either hematite or magnetite) by ship, usually from far afield, Brazil, Australia or South Africa, for example. The raw materials are blended and prepared to meet the specification for steel production in large ...

The iron and steel manufacturing process requires an unbroken flow of materials between production stages, including blast furnace, basic oxygen furnace, continuous caster and rolling mill. Shutting down and restarting a given operation during the steelmaking process can be costly.

12.5.1 Steel Minimills 12.5.1.1 General The U.S. steel industry produced about 106 million tons of raw steel in 2006, and approximately 93 "minimills" that recycle ferrous scrap metal accounted for 57 percent of the total U.S. steel production. The production of steel in minimills has increased dramatically over the past 30 years.

Due to the previously disclosed fire at the Company's steel mill in May 2021, finished steel sales volumes for the quarter are expected to be down 53% year over year.
