Recent progress and future trend on grain-oriented silicon steel

Secondary recrystallization mechanism has rapidly progressed together with the advance in manufacturing process for grain-oriented silicon steel. The acquired inhibitor method was developed to avoid the metallurgical problem for controlling secondary recrystallization. As magnetic domain structure is affected largely by core loss, pinning of domain wall movement and surface closure domains must be removed to reduce con loss further.
