American steel mills have the capacity to produce more than 9 million tons of structural steel each year. Approximately 3.5 million tons of structural steel were used in the U.S. in 2017. Existing American structural steel manufacturers can easily meet all domestic demand.

iron & steel - US EPA

Integrated mills produce steel from iron ore using a blast furnace, which consumes carbon, primarily in the form of coke, to convert iron ore to molten iron, known as “pig iron.” A basic oxygen furnace (BOF) then converts the pig iron, along with up to 30% steel scrap, into refined steel.

Steelmaking - Wikipedia

Process for producing steel from iron ore and scrap. Steel mill with two arc furnaces. Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Canadian steel producers recycle approximately 7 million tonnes of steel annually. Benzene emissions in , primarily from integrated steel mills’ coke operations, show a 90% reduction since 1990, the result of improvement projects implemented at a number of facilities.

Basic oxygen steelmaking - Wikipedia

Basic oxygen steelmaking, also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as basic because fluxes of burnt lime or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter

Primary Mill Fabrication - ASM International

Primary Mill Fabrication A gener Al di AgrAm for the production of steel from raw materials to finished mill products is shown in Fig. 1.
