Silicon steel sheet is a special steel that is widely used in the electrical industry. This material is made of high-purity silicon and cold-rolled non-oriented silicon steel. Silicon steel sheet has unique properties and advantages that make it an indispensable material in key equipment such as transformers, generators and motors. This article will introduce the advantages and application fields of silicon steel sheets.
1. Low loss and high permeability:
A notable feature of silicon steel sheet is its low loss and high magnetic permeability. This is due to the reduction of tiny magnetic domain wall losses between the oriented and non-oriented silicon steel sheets and the optimization of the size and shape of silicon grains. This low loss and high magnetic permeability enable the silicon steel sheet to reduce energy loss when current passes, and provide high-efficiency magnetic permeability.
2. Reduce eddy current loss:
Eddy current losses are generated in an alternating magnetic field, which leads to current consumption and heat generation. Silicon steel sheets reduce eddy current losses by introducing silicon particles into the material. Silicon’s high resistivity reduces the intensity of eddy currents, thereby reducing energy loss and heat generation. This makes silicon steel sheets particularly suitable for use in equipment such as high-frequency transformers and motors.
3. Suppression of magnetic saturation and noise:
The high saturation magnetic induction of silicon steel sheet enables it to withstand high magnetic flux density without saturation. By suppressing magnetic saturation, silicon steel sheets are able to reduce magnetic field fluctuations in transformers and motors, thereby reducing noise and mechanical vibration. This is very important for equipment that requires low noise and smooth operation.
4. Environmental protection and sustainability:
The production process of silicon steel sheets is relatively environmentally friendly. Compared with ordinary steel, the manufacturing process of silicon steel sheet involves less energy consumption and resource consumption. In addition, its efficient energy conversion characteristics mean that in equipment using silicon steel sheets, less electrical energy is lost, making the entire power system more energy efficient.
Silicon steel sheets are widely used in the following fields:
– Transformer: Silicon steel sheet is used to make the iron core of the transformer. Their low losses and high magnetic permeability allow transformers to transmit and convert electrical energy efficiently.
– Generators and motors: As the core material of motors and generators, silicon steel sheets can provide efficient power conversion and output capabilities.
– Magnetic sensor: The excellent magnetic permeability of silicon steel sheet makes it an ideal material for magnetic sensor and magnetic field detector.
– Electric vehicles: Silicon steel sheets play an important role in the drive system of electric vehicles, reducing energy loss and increasing battery life.
