Advanced Technologies for NGO and GO Electrical Steel

Electrical steel is a special steel utilized for specific magnetic properties. Non-grain oriented (NGO) electrical steel is used for high-frequency electric motors, while the energy efficient grain oriented (GO) electrical steel is used for transformers and charging infrastructure. Fives provides process expertise, cold rolling mills and strip processing lines with advanced technology including furnace atmosphere management, induction heating technology for ultrarapid heating, and 20-high CRMs to achieve desired thickness and flatness. This paper describes how technology aids electrical steel production and how it has led to record performances in strip temperature, rapid induction heating, H2 atmosphere and cold rolling.
