Developments in the production of grain-oriented electrical steel

Effect of Niobium on Precipitates and Texture Evolution of Fe-3% Si Grain-oriented Electrical Steel Annealed Hot Band

“…At present, dominating technologies of producing high magnetic induction grain-oriented electrical steel choose AlN as the main inhibitor, and add small amount of element which precipitates in grain boundary to form auxiliary inhibitors. [6][7][8][9] Niobium is a kind of typical grain boundary precipitation element which has strong tendency to form carbonitride instead of forming oxide or sulfide.…”

Twin Roll Casting of Steels: An Overview

“…[3][4][5] As thickness of the as-cast strip is approximately close to the final product thickness, there is the possibility of eliminating the expensive and energy-consuming downstream rolling and finishing steps which are necessary in conventional continuous casting (CCC) and thin-slab casting (TSC). Using DSC technique, casting and rolling steps are merged into a single compact, efficient and continuous operation step resulting in many economic, environmental and technical benefits in the steelmaking industries.…”

Magnetic losses reduction in grain oriented silicon steel by pulse and continuous fiber laser processing

“…To reduce the eddy-current losses, domain refinement techniques are being investigated by eliminating unfavorable internal stresses and providing favorable stresses that refine the magnetic domains. 10 Several different domain refinement techniques, such as mechanical scratching, plasma irradiation, spark ablation and laser scribing have been studied for many years. All these methods can induce favorable stress that refines the magnetic domains due to mechanical or thermal strains introduction.…”
