ABSTRACT:
A method of producing amorphous alloy thin strip suitable for use in commercial frequency band transformers utilizes a high-quality molten steel suitable for electromagnetic silicon steel plates but containing insufficient silicon and boron. The molten steel is divided when tapped out of a converter or after a vacuum degasifying steel making process, and silicon and boron are added with heating to create the desired composition. The molten steel is formed into thin amorphous alloy strip by quenching.
