Abstract
The invention aims at a method of producing a metal strip on a continuous treatment line comprising a de-scaling station coupled with a cold rolling section.According to the invention, in order to adapt to a change in the production constraints, such as a spool change, the rolling speed is caused to vary on a very wide range down to less than 1 m/min and the cold rolling operation is done between working rolls the diameter of which is so small that, on said whole wide speed variation range, the rolling strength to be applied remains compatible with the product thickness adjustment possibilities, taking the characteristics thereof into account.
