Earth, air and firE. Tata Review76 April 2013 April 2013 nn Tata Review 77 PHOTOFEATURE F or more than 3,000 years, humans have known how to make tools, weapons and ornaments from iron. Known as a metal of antiquity, iron is one of the building blocks of modern civilisation. Indeed, there was a time when iron was more valuable than gold. The basic process
In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams ...

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills.
Steel strips are hot rolled in a temperature range from 800 to 1 200°C, and an oxide film called scale forms on the steel surfaces during heating and rolling. If steel is rolled with the scale on the sur- face, it leads to surface defects, and to prevent this, scale is usually removed with high-pressure water immediately before the steel goes into mill stands.
