Hot Rolling
After passing through the reversing hot rolling or "break down" mill, the material is fed through a number of non-reversing tandem mills (400–550°C) where the thickness of the strip is set, before it is wound at the coiler (240–380°C). The material undergoes a reduction in its thickness from typically 600 mm down to 6 mm.
