Rails and Rail Steel IspatGuru

May 05, 2013· The thinnest part of the rail section after its rolling in the rolling mill cools the fastest. Since the rail head contains a large mass it retains the heat to a higher degree. Hence, the contraction in the head is lesser than at the rail flange with the result that, during cooling after rolling, the rail sweep naturally or pull towards the its

History. Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes.. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company steelworks
