|1. (WO2018059006) SILICON STEEL PRODUCT WITH LOW IRON LOSS FOR LOW-NOISE TRANSFORMER, AND MANUFACTURING METHOD THEREOF|
|Applicants:||BAOSHAN IRON & STEEL CO., LTD.
|Title:||SILICON STEEL PRODUCT WITH LOW IRON LOSS FOR LOW-NOISE TRANSFORMER, AND MANUFACTURING METHOD THEREOF|
A silicon steel product with low iron loss for a low-noise transformer, and manufacturing method thereof. The silicon steel product comprises: a silicon steel substrate, a magnesium silicate bottom layer formed on a surface of the silicon steel substrate, and an insulation coating applied on the magnesium silicate bottom layer. The magnesium silicate bottom layer has a normal reflection (R) of 40-60% for visible light. The silicon steel product with low iron loss for a low-noise transformer achieves normal reflection of visible light by stringent control of the magnesium silicate bottom layer of the silicon steel substrate. The magnesium silicate bottom layer has a uniform gloss to reduce iron loss and minimize magnetically driven expansion and contraction, resulting in low noise and making the silicon steel product especially suitable for a transformer.
