ArcelorMittal Nippon Steel India (AM/NS India) ordered a coupled Pickling Line and Tandem Cold Mill (PLTCM) from Primetals Technologies for its site in Hazira, Gujarat. The project is expected to be commissioned by July 2024.
Primetals Technologies is responsible for engineering, supply of main and auxiliary equipment and electronics and automation. The existing hot-strip mill will supply a hot-rolled coil to the new PLTCM line. After pickling, the coil will either be processed as hot-rolled pickled and oiled steel or sent to the tandem cold mill for cold rolling. The tandem cold mill is designed as a 6-high Universal Crown Control Mill (UCM) for producing steel grades. The UCM excels in eliminating undesirable contact areas between the rolls, resulting in improved flatness of the strip and high reduction levels.
AM/NS India’s new pickling line will feature Primetals Technologies iBox technology, consisting of an energy-efficient pickling tank. Made of polypropylene, the iBox improves pickling capacity without the need for continuous recirculation of acid by running pumps. In addition, the Acid Concentration Control System (ACCS) regulates acid supply in each tank by using Primetals Technologies’ proprietary algorithm to predict descaling distribution and pickling reaction.
