From rolling slab to semi-finished cold rolled coil in one line.
First the rolling slab has its outer border zone removed by a scalping operation before being preheated in preparation for hot rolling. The hot rolling process is done on a reversing mill before the resulting aluminium plate is quenched and immediately cold rolled in line, before being wound into a coil.
Here the surface cleanliness -free from oxide and other foreign particles - and the material's essential flatness are controlled with sophisticated mill control systems.
The coil is then transferred to Litho Centre or Coil Mill for further processing.
