Introduction

Silicon steel is an extremely low-carbon ferrosilicon alloy material with a silicon content of 0.5% to 4.5%. Silicon steel has the characteristics of high magnetic permeability, low coercivity, and large resistivity. According to different production processes, it can be divided into hot-rolled silicon steel and cold-rolled silicon steel; oriented silicon steel is mainly used in the manufacture of transformers (iron cores), and can also be used in large motors (hydropower, wind power) and other fields.

Applications

Electrical steel (silicon steel sheet) is mainly divided into two categories: grain-oriented electrical steel and grain non-oriented electrical steel. The direction of easy magnetization grains of oriented electrical steel is distributed along the rolling direction. The rolling direction has excellent characteristics such as high magnetic induction, low iron loss and low magnetostriction. At the same time, it can also be processed by magnetic domain refinement technology to obtain lower iron Loss of performance, widely used in the field of transformer industry. The grain direction of non-oriented electrical steel is randomly distributed, and the electromagnetic properties are uniform in all directions. It is widely used in the motor industry.
