PREPARATION METHOD OF GLASSLESS GRAIN-ORIENTED SILICON STEEL AND PRODUCT THEREOF

A preparation method of glassless grain-oriented silicon steel includes the following operations. During a decarburization annealing, a thickness of an oxide film on a surface of strip is 1.5-2.5 μm; an atomic weight ratio of Si element and Fe element in the oxide film satisfies: Si/(Si+Fe)≥0.76; du...
