Management of the entry of a new coil in an installation for the continuous treatment of metal strip, specially applicable for pickling lines

摘要

The invention proposes a new method for managing the entry of a new coil into a continuous strip treatment line, in particular for the passage of short coils. The overall time for the realization of the joining process for the new coil (11') is divided into at least two periods realized in at least two successive parts (3, 4) of the inlet section (1) of the installation and a variable length of the strip is placed in reserve in at least one intermediate accumulator (5) in order to save an interval of time of variable duration between the periods of the joining process. An independent claim is also included for an installation for the treatment of a strip product fed by successive coils using this method of managing the entry of a new coil.
