Mutual Influence of Electrical Insulating Coatings and Structural Barriers on the Level of Magnetic Losses in Anisotropic Electrical Sheet Steel

摘要

Changes in the magnetic losses that occur in the electrical-sheet anisotropic steel under the joint influence of electrical insulating coatings and structural barriers in the form of scratches have been investigated. It is shown that both the coatings and scratches separately reduce the level of magnetic losses to a considerable extent, but their combined influence is not additive. The work was performed under the conditions of the Verkh-Isetsk Metallurgical Works (OOO VIZ-Stal').
