Hot Rolled High Silicon Steel Transformer Steel is a special electrical steel designed for power transformers and motor cores, with high silicon content and specific electromagnetic properties.

Product Parameters

Basic Definition and Composition

1. Main ingredients: Silicon (Si) content is usually between 3.0% and 4.5%, carbon (C) content is extremely low (<0.005%), and contains a small amount of alloying elements such as aluminum (Al) and manganese (Mn).

2. Hot rolling process: Through high-temperature rolling forming, compared with cold-rolled silicon steel, its grain size is larger and the surface roughness is higher, but the cost is lower.

Core Characteristics

1. High magnetic permeability and low iron loss: The addition of silicon significantly reduces eddy current loss and hysteresis loss, and improves electromagnetic efficiency.

2. High resistivity: Silicon element increases resistance and reduces eddy current heating in alternating magnetic fields.

3. Weak mechanical properties: High silicon content leads to increased brittleness of the material, and excessive bending or stamping should be avoided during processing.

Main application areas

1. Power transformer core: especially suitable for small and medium-sized transformers or cost-sensitive scenarios.

2. Motors and generators: used as stator and rotor materials in some industrial motors.

3. Reactors and inductors: using their stable magnetic properties.
