Cutting-Edge Process Technologies for Enhanced Silicon Steel

The booming electric vehicles market is driving the development of non-grain oriented silicon steels with high flux density and minimal core losses for the use in high-frequency electric motors, as well as high-energy-efficient grain-oriented electrical steels due to the need of charging infrastructures. The process routes for new high-performance grades require some advanced technologies such as ultrafast heating by transverse flux induction, high-temperature furnace operation, flexible and uniform cooling, and reliable furnace atmosphere control. This paper describes these technologies which have been recently widely implemented on new processing lines and through upgrades of existing operations.
