Work process for applying a defined surface roughness to a metal strip

A process for applying a defined surface roughness to a metal strip for preventing a sticking of the metal strip during an annealing procedure in an arrangement comprising a reversing roll stand for cold rolling the metal strip, an annealing station for receiving the metal strip after the metal strip has been cold rolled, and a temper roll stand having flattening rolls for conducting at least one flattening pass of the metal strip after the metal strip has been annealed in the annealing station, the process for applying a defined surface roughness comprising the steps of:

• temporarily replacing the flattening rolls of the temper rolling stand which is used for conducting at least one post-annealing flattening pass of the metal strip with roughing rolls;
• wet rolling the metal strip through the roughing rolls in the temper rolling stand before the metal strip is received in the annealing station for applying a defined roughness to the metal strip;
• and
• removing the roughing rolls and reinserting the flattening rolls into the temper rolling stand after the step of wet rolling so that the temper roll stand is usable for conducting at least one post-annealing flattening pass of the metal strip with the flattening rolls.
