GRAIN-ORIENTED ELECTRICAL STEEL SHEET - A simplified explanation of the abstract

This abstract first appeared for US patent application 18562217 titled 'GRAIN-ORIENTED ELECTRICAL STEEL SHEET

The grain-oriented electrical steel sheet described in the patent application achieves low iron loss and low magnetostriction while maintaining excellent transformer properties.

The sheet has a thermal strain-imparted region that extends linearly in a direction crossing the rolling direction.
In the strain distribution of the thermal strain-imparted region, the strain at both ends is tensile strain larger than the strain at the center.
This unique design helps reduce iron loss and magnetostriction, improving overall transformer performance.

Potential Applications: - Transformer manufacturing - Electrical equipment production - Power distribution systems

Problems Solved: - High iron loss in electrical steel sheets - Excessive magnetostriction affecting transformer efficiency

Benefits: - Improved transformer performance - Energy efficiency - Reduced power losses

Original Abstract Submitted

Provided is a grain-oriented electrical steel sheet that achieves both low iron loss and low magnetostriction and has excellent transformer properties. The grain-oriented electrical steel sheet has a thermal strain-imparted region extending linearly in a direction crossing the rolling direction, and in the strain distribution in the rolling direction of the thermal strain-imparted region, the strain at both ends of the thermal strain-imparted region is tensile strain larger than the strain at the center of the thermal strain-imparted region.
