摘要： According to exemplary embodiments of the present invention, a process for production of an amorphous alloy can be provided at low cost by, e.g., efficiently removing magnetic-property-degrading Al and Ti when using inexpensive Fe—B or scrap as an amorphous alloy raw material. An exemplary embodiment of the process for production of an Fe-based amorphous alloy ribbon can comprise, by mass, e.g., 2 to 4% of B, 1 to 6% of Si, and a balance of Fe and unavoidable materials is provided. For example, it can be determined whether the molten alloy obtained by melting a main raw material has a Ti concentration or Al concentration of 0.005 mass % or greater: When such even occurs, iron oxide source having an iron content of 55 mass % or greater can be added thereto to reduce both Ti and Al to less than 0.005 mass % by oxidative removal. Alternatively, it is possible to determine whether the main raw material has a composition whose Ti concentration or Al concentration is 0.005 mass % or greater, and when it does, an iron oxide source having an iron content of 55 mass % or greater is precharged into a melting vessel together with the main raw material.
