PRODUCT FROM TEXTURED SILICON STEEL WITH LOW LOSSES IN IRON FOR TRANSFORMER WITH LOW NOISE LEVEL AND METHOD OF PRODUCTION THEREOF Russian patent published in 2020 - IPC C22C38/00 C21D8/12 H01F1/16 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to a product from textured silicon steel used for making transformers with low noise level. Product contains a silicon steel substrate, a lower layer of magnesium silicate coating formed on the surface of the silicon steel substrate, and an insulating coating applied on the lower layer of the magnesium silicate coating. Lower layer of magnesium silicate coating has normal reflecting power R for visible light from 40 to 60 %.

EFFECT: product has low losses in iron making 1_02 W/kg or less, and magnetostriction, which provide its use for making transformers with noise level of 58_9 dBA or less.
