Silicon Steel Coil Comparison

Cold Rolled Steel Coil

Advantages:

Non-oriented silicon steel has isotropic magnetic properties, relatively low iron loss, good machinability and relatively high material cost performance. These advantages make silicon steel widely used in motors, generators and small transformers.

Disadvantages:

Non-oriented silicon steel has inferior magnetic properties to oriented silicon steel, has higher eddy current loss, and thickness restrictions may affect the design and performance of high-efficiency power equipment manufactured by some factories.

After comparing these two silicon steels, in terms of cost performance, non-oriented silicon steel may be more suitable for electrical equipment that requires uniform magnetic properties and economy, but in applications with high efficiency and low loss requirements, it is recommended that customers may need to consider oriented silicon steel.

Precautions for application of non-oriented silicon steel

When using non-oriented electrical steel (NOES) coils to manufacture certain electrical equipment, we may need to pay attention to the following key issues to ensure the best performance and life of the equipment.

1. Select the material and specifications of the Steel Plate

We need to select the most suitable silicon steel grade and corresponding grade. Different silicon steel grades and steel coil grades have different magnetic and mechanical properties. The appropriate silicon steel grade should be selected according to the specific requirements of the equipment.

At the same time, customers also need to consider the material thickness: the thinner the thickness, the lower the eddy current loss, but the processing difficulty and cost also increase accordingly. Therefore, a balance needs to be struck between performance and cost.

2. Deep processing and treatment of cold-rolled steel coils

(1) Stamping process: When stamping silicon steel sheets in the factory, technicians need to use precise stamping equipment and molds to ensure the processing accuracy and surface quality of silicon steel. This is to ensure that burrs and microcracks should be avoided during the stamping process.

(2) Lamination process: Lamination is also a key process in the manufacture of silicon steel core. The factory must ensure that the lamination is tight and uniform during processing, which will reduce air gaps and losses.

(3) Insulation coating: The surface of silicon steel sheets is usually coated with an insulation layer to reduce eddy current losses. During processing and assembly, damage to the insulation layer should be avoided.
