ABSTRACT:
An installation for treating metal strip comprising a pickling line made up of a series of tanks filled with a pickling solution heated to a certain temperature, and through which the metal strip is successively passed before passing into a cold rolling mill, each tank being associated with an arrangement for adjusting the temperature of the solution in the tank, according to its position in the line. The installation comprises at least one complementary heating arrangement associated with a regulation system for maintaining the solution at the desired temperature according to variations in overall energy conditions, and comprising a heat pump for recovering at least part of the heat needed from a cooking circuit of the cold rolling mill.
