NeoKoil, silicon steel processing lines

Printable Version

Silicon steel also known as electrical steel (0.5 to 4.5% of silicon) is traditionally used in the production of transformers, inductors, motors and generators, and is gaining applications in the energy, electric car, appliances, and modern generator/transformer markets. It's a special steel tailored to produce specific magnetic properties, resulting in low power loss per cycle, low core loss, and high permeability that is extremely sensitive to produce. 

Fives designs and supplies NeoKoil® silicon processing lines and cold rolling mills dedicated to the production of non-grain oriented (NGO) and grain oriented (GO and HiB) grades. The scope of supply includes annealing & pickling lines (APL) and annealing & coating lines (ACL) for NGO grades; as well as decarburizing & coating lines (DCL) and flattening & coating lines (FCL) for GO grades.

Fives provides process expertise, energy-saving technologies and proprietary equipment, including DMS 20Hi cold rolling mills, complete terminal equipment, degreasing sections, annealing furnaces and curing ovens, furnace atmosphere management solutions (decarburization, nitriding, etc.) and induction heating technologies.

Cold rolling mills

Cold rolling mills

The DMS 20Hi cold rolling mill offers simple and safe operation and maintenance, as well as optimum strip productivity, high rolling speeds and a minimum strip thickness of 0.04 mm. Recent improvements include 10% increase in strip productivity; improved strip flatness tolerances for GO, NGO or HiB quality; fast and reliable mill/wiper roll change and a cleaner operating environment.
