Selection of Grain-Oriented Electrical Steel for Reactors
Grain- oriented electrical steel (GOES) is a critical material in reactor core design. Its material properties directly affect reactor efficiency, noise level, size, and operational stability. In reactor applications, different types of GOESvarying in magnetic properties, thickness, coating, and processing—are selected to meet specific operating requirements. 1. Conventional Grain-Oriented Electrical Steel (CGO) Characteristics: Exhibits good directional magnetic properties, with high permeability and relatively low core loss along the rolling direction. Applications: Suitable for conventional reactor designs where energy efficiency requirements are moderate and cost sensitivity is a key consideration. Advantages: Cost-effective, mature processing technology, and widely used in medium- and low-voltage reactors. 2. High Magnetic Induction Grain-Oriented Steel (Hi-B) Characteristics: Optimized grain orientation and inhibitor control based on CGO, resulting in highe...
