1. INTRODUCTION: Oriented electrical steel, also known as cold-rolled oriented silicon steel, refers to cold-rolled electrical steel containing 2.9% to 3.5% Si, and the crystal structure of the steel plate has certain rules and directions. Oriented electrical steel is an indispensable soft magnetic material in the power industry, mainly used in transformers, rectifiers, reactors and large motors and other industries.
