Rolling of Metals

–Rolling at elevated temperatures to lower the strength of the material –Apply longitudinal tension to the strip during rolling –back tension on the pay-off reel or front tension on the take-up reel • Grind rolls with a camber to prevent crowning of the rolled strip • Radius of maximum camber point generally 0.25 mm

Modeling and exploiting the strip tension influence on ...

In their setup, the desired strip roughness can be achieved by combination of different rolling forces on the two mill stands. However, most temper rolling mills use a single mill stand. In these cases strip tension might be an alternative, as it is widely adjustable and influences the transfer ratio via its effect on the roll pressure.
