The long and colorful history of Chicago's steel mills begins in 1857 with the opening of the city's first steel mill, North Chicago Rolling Mill Company. Within three years, the mill became one of the biggest companies in the area, with its primary focus on making rails for the railroad. Slowly but surely, more steel mills opened for business.

In the late 18th century, Oliver Evans invented the first automated flour mill in the United States that did the work of seven men (Basey 7). It used millstones, had an enormous amount of levers and pulleys, and was very noisy. Evans' mills were water powered, so they were situated along rivers.

At their steel mills, TCI installed the nation's first large-scale duplex mill, which employed both Bessemer converters and tilting, open-hearth furnaces. The Bessemer converters were required to rid molten pig iron of its relatively high silicon content, and the molten metal was then transferred to the tilting open-hearth furnaces, where ...

The windmill has been used as a source of electrical power since P. La Cour's mill, built in Denmark in 1890 with patent sails and twin fantails on a steel tower. Interest in the use of windmills for the generation of electric power, on both single-user and commercial scales, revived in the 1970s.

Illinois Steel (by then also known as Federal Steel, a holding company created by Chicago lawyer Elbert H. Gary in 1898) became part of this giant entity. U.S. Steel closed some of the Chicago-area mills, but the South Works—which employed about 11,000 people in 1910—stood as one of its largest plants.

The town grew quickly as laborers from all over the world came to build the mills. After the first steel mills opened in 1909, U.S. Steel continued to expand. Soon, related industries (like American Bridge. Co., American Sheet and Tin Plate Co., National Tube Co., American Steel and Wire Co., American Locomotive Co., American Car and Foundry Co ...

By the turn of the Century, Homestead was a bustling community, home to one of the most important plants of The Carnegie Steel Company. Because of its location, Homestead proved an ideal place for the steel industry to take root – the Monongahela ...

Birmingham Steel's four minimills rank among the most efficient in the nation, producing a ton of steel in 1.4 worker-hours. Its mill products are made from recycled scrap metal and include reinforcement bars (used in the construction of concrete buildings and highways) and steel rounds, flats, squares, angles, strips and channels (used in the ...

1740 – The crucible steel technique is developed by English inventor Benjamin Huntsman. 1779 – The power of stream reaches steel mills, meaning that they no longer needed to be close to water as was previously necessary. 1783 – Englishman Henry Cort invents the steel roller for steel production. 1794 – Welsh inventor Phillip Vaughn ...

U.S. Steel substantially augmented its Cleveland facilities in 1907-08 with the construction of wire and strip mills on the OHIO AND ERIE CANAL south of Harvard Ave. Galvanizing and barbed fence departments were added later, and by 1932 the Cuyahoga Works was one of the largest wire mills in the country and boasted the world's largest cold ...
