Abstract (en)
[origin: WO2008155320A1] In order to reduce operating costs in a rolling train (2) for producing a sheet metal (12), working rolls (8) of the rolling train (2) are provided with a special coating (38) composed of a ductile base material (39) having hard material particles (40) embedded therein. In addition, it is provided that during rolling the working rolls (8) are pressed against the sheet metal to be rolled (12) with a rolling pressure (p) of higher than 2 GPa. Due to these high pressures, it is possible to achieve higher rolling speeds and/or reduce the amount of working rolls (8) involved.
