Abstract

In this paper are described the following Pickling Line projects: Annealing and Pickling Line for Stainless Steel (Hot and Cold band) commissioned in Italy on 2010; Annealing and Pickling Lines for high grades Silicon steel (Oriented and not-oriented) including efficient Si- removal commissioned in China on 2009; Continuous Pickling Lines for low Carbon Steel re- built in Russia on August 2004; Revamping of Continuous Pickling line for low carbon steel in Poland performed on August 2009; Push Pull Pickling Line with Acid Regeneration Plant Zero Effluent Technology for Compact Cold Mill Complex in Romania (under way). The main aspects of the pickling technologies and the techniques are described in the different plants considering also the jobs typologies as new green field plant, overall revamping, transfer and modernization or simply modernization. Annealing technologies of stainless steel and electrical steels upstream of the pickling process are described.
