Abstract

The iron-based amorphous nano master alloy belongs to the field of metallurgy, and its chemical composition mass percentage is: Si is 15.7, B is 3.8, Nb is 11, Cu is 2.4, and the balance is Fe. The smelting method is: add industrial pure iron - ferroniobium - industrial silicon - electrolytic copper boron iron into the intermediate frequency smelting furnace in sequence; (2) preheat with low power first, and then heat with high power; (3) wait After the raw materials are completely melted, carry out alternating stirring with large and small power, and at the same time cooperate with the shaking furnace with medium and small range; when the temperature rises to 1400 ° C, keep it warm for 5 minutes; (4) Finally, slag and tap. The invention solves the problems of burning loss of raw materials, difficulty of melting high-melting point alloys and the like. The amorphous and nanocrystalline strips produced by using the master alloy have multiple advantages such as uniform composition, good toughness, significantly improved magnetic properties, and reduced manufacturing costs.
