Roughing Mill an overview ScienceDirect Topics

The evolution of microstructure in hot rolling of aluminium alloys depends on the interaction of the main process parameters: temperature, strain, strain rate and inter-stand time (Hirsch, 2006a, 2006b). The hot strip geometry and microstructure also affects the final sheet geometry and properties, also after final cold rolling, so special attention must be paid to the hot mill process configuration and parameters.
