After passing through the reversing hot rolling or "break down" mill, the material is fed through a number of nonreversing tandem mills (400550°C) where the thickness of the strip is set, before it is wound at the coiler (240380°C). The material undergoes a reduction in its thickness from typically 600 mm down to 6 mm.
