Abstract
The paper describes an ultrasonic method for the formation of locally deformed zones (LDZ) in the form of mechanical scratches applied to the surface of anisotropic electrical steel of nuclear power plants to crush its domain structure in order to reduce the total magnetic losses Р. It is shown that, as a result of such processing, using the example of a 3407 type steel, the value of P decreases by an average of 10-15%. It has been established that exposure to ultrasound leads to a significant increase in the rate of scratching.
