The present invention provides a method for producing an iron-based amorphous alloy ribbon at a low cost.

により鉄損の小さな磁気特性の優れた材料が要望され、
非晶質合金が有望視されている。Traditionally, silicon steel sheets have been exclusively used as iron cores for electric quadramps, etc., but as the demand for energy conservation increases, there is a demand for materials with better magnetic properties and lower iron loss.
Amorphous alloys are seen as promising.

C-based alloys that can be made amorphous and have excellent magnetic properties generally contain more than 2% by weight of boron, which results in increased raw material costs and a significant cost for commercialization. It was a hindrance.

お残されている。(Problems to be Solved by the Invention) Compared to an amorphous alloy ribbon made from high-purity boron as a raw material, the performance of an alloy ribbon made using ferroboron produced by the smelting reduction method according to the above-mentioned conventional technology has a lower magnetic property. However, there are still some problems that need to be resolved.

とを特徴とする鉄系非晶質合金薄帯の製造方法である。This invention uses a ferroboron alloy produced by a smelting reduction method that has a low Ti content as a boron raw material used to produce a molten metal for rapid cooling when producing an iron-based boron-containing amorphous alloy ribbon by an ultra-quenching method. Ti content 0 obtained by carrying out one or both of sorting and Ti removal treatment
．． This is a method for producing an iron-based amorphous alloy ribbon, characterized by using a low Ti ferroboron alloy having a weight of 0.04 weight or less.

結果を表１に示した。(Function) Now, in terms of weight percent, it is 81.5 to 3.5%, Si5
Fe-based amorphous alloy containing ~12% exhibits excellent magnetic properties, but we investigated the relationship between Ti content and magnetic properties (iron loss and magnetic flux density) of this Fe-B-5i-based amorphous alloy. The results are shown in Table 1.

純度ボロンの場合はど著しい低下は見られない。Table 1 Iron loss: Value at magnetic flux density 1.3T, 50Hz Magnetic flux density: Value at magnetic field strength 100^/11 As is clear from Table 1, as the Ti content increases, the iron I member also increases, and the magnetic flux Density is decreasing. In particular, when melt-reduced ferroboron is used, it can be seen that the iron loss increases quite rapidly when the Ti content in the ribbon exceeds 0.04%. Note that a similar tendency is observed when high-purity boron and high-purity Ti are used. Furthermore, JP-A No. 59-64143 also points out the negative effects of Ti, and when high-purity boron is used, the magnetic properties drop sharply when the Ti content exceeds 0.02%. When using high-purity boron, no significant decrease is observed.

の向上が可能となる。Therefore, by using the smelting reduction method that does not require electricity and can use low-quality and low-grade raw materials such as fine ore, it is possible to significantly reduce the cost of manufacturing amorphous ribbon. A raw material with a low Ti does not necessarily mean a high quality or expensive material, but it is possible to improve the magnetic properties simply by selecting a low Ti ferroboron alloy or by performing Ti removal treatment.

Table 1 shows the iron loss and magnetic flux density after annealing in a 200e magnetic field for 60 minutes. Ti content is 0.04
When it is less than % by weight, it is excellent in both iron loss and magnetic flux density.
