Abstract

A process for the continuous pickling in a non-oxidizing acid bath of hot-rolled steel strips, characterised in that the strip is subject to the pickling action of the bath, additioned of a pickling catalyst, under turbulent conditions. An embodiment of the device apt to carry out the aforesaid process is shown in figure 1. <IMAGE>
