slitting mill with series of disc cutters to slit flats into narrow strips. As per record available, rolling of iron into thin flats was first done in Bristol, the UK in 1666. As per a pamphlet on 'British Iron Trade published in 1725,' all bars were made by hammering even at that date. By 1682, large rolling mills for hot rolling of
The costs of producing steel have declined substantially from building a conventional hotrolled steel mill down to the new minimill technology that requires only scrap metal, an electric furnace, and 300 workers rather than iron ore raw materials, enormous blast furnaces, rolling mills, reheating furnaces, and thousands of workers.

A number of features found in traditional compositions and in Menzel's other large canvases can be seen here: note, for example, the painting's triptychlike structure ...
Steel Forming, Casting, Alloying: The early metals shapers, the smiths, used hand tools to form iron into finished shapes. Essentially, these consisted of tongs for holding the metal on an anvil and a hammer for beating it. Converting an iron bloom into a wroughtiron bar required considerable hammering. Waterdriven hammers were in use by the 15th century in Germany, but heavy hammers ...
The history of rolling in Pennsylvania began with John Taylor in Chester. In 1746, Taylor built a rolling mill which allowed the Sarum Iron works to mass produce iron products at high quality for significantly cheaper prices. When Britain learned of these cheap goods being produced in the colonies, it passed the Iron Act of 1750.

Arguably, the key development came in 17834, when Henry Cort introduced the puddling and rolling techniques. These were ways of getting all the impurities out of iron and allowing largescale production, and a vast increase in it. The iron industry began to relocate to coal fields, which usually had iron ore nearby.
The impulse for The Iron Rolling Mill most probably came from Menzel's friend Paul Meyerheim, who was working on a series on the history of the railways for the industrialist Albert Borsig. In 1872 Menzel travelled to Königshütte in Upper Silesia in order to familiarize himself with factory conditions there, and spent weeks making hundreds ...
