Description

저자왜 고포화 자속밀도의 고주파용 인덕터 재료Why high frequency inductor material with high saturation magnetic flux density

본 발명은 Fe-Si-B계에 Nb를 첨가하여 자왜를 줄여 철손을 줄이고 Ni를 첨가하여 연자성을 향상시킴으로써 저자왜 고포화 자속밀도를 갖게하여 고주파용 인덕턴스 소자 및 특수 디바이스에 응용할수 있는 Fe기 비정질 합금재료에 관한 것이다.The present invention reduces the iron loss by adding Nb to Fe-Si-B system, reduces iron loss and improves the soft magnetic property by adding Ni, which has a low distortion magnetic flux density, which can be applied to high frequency inductance devices and special devices. The present invention relates to an amorphous alloy material.

종래에는 고주파용 인덕턴스 소자 및 특수 디바이스에 있어서 출력코일은 직류전류에 의해 간단하게 자속이 포화하지 않고 교류분에 대한 인덕턱스 값을 가져야 하므로 재료의 특성으로 고포화자속 밀도를 필요로 하고 코어에 공극을 넣는 것에 의해 함투자율을 얻어서 직류중첩 특성, 전원효율과 실제 사용성으로 높은 온도까지 큰 값을 가져야 하는등 많은 제약을 받고 있다.Conventionally, in high frequency inductance elements and special devices, the output coil should not simply saturate the magnetic flux by the DC current but have the inductance value for the AC component. By inserting, the permeability of the DC superimposition characteristics, power efficiency and practical usability have a lot of constraints such as to have a large value up to high temperature.

따라서, 본 발명은 종래의 이와같은 문제점을 해소하여 실용상의 효율성을 높이는 재료를 제조하기 위한 것으로 제조공정과 실시예를 통해서 설명하면 다음과 같다. 합금 조성율(Fe1-x, NiO.10 Nbx)83 Si5 B12(0.04

0.10)로 하였고 이 조성의 합금을 만들기 위하여 99.9% 순도의 Fe, Nb, Ni와 99.95% Si99.8%의 B를 10gr까지 정확히 달아 잘 혼합한 후 치밀하게 압축시킨 후 15KW, 10KHz의유도 용해로에서 융용시켜 모합금을 제조한 후 통상의 비정질 금속리본 제조방법인 단롤법에 의해 리본을 만들었다. 구리롤의 직경은 300mm로 하고 석영관은 10mmSlit를 이용했다. 진공챔버 압력은 450Torr 하고 He gas 분사압력은 0.05-0.07Kgf/cm2으로 하여 10mm 폭 20 두께의 리본을 제조하여 통상의 방법으로 코어를 만들어 측정을 했다.Therefore, the present invention is to produce a material that improves the practical efficiency by solving such a conventional problem as described through the manufacturing process and examples as follows. Alloy composition ratio (Fe1-x, NiO.10 Nbx) 83 Si5 B12 (0.04

0.10) and 99.9% pure Fe, Nb, Ni and 99.95% Si99.8% B are precisely weighed up to 10 gr, mixed well and compactly compressed, and then pressed in an induction melting furnace of 15KW and 10KHz. After fusing to prepare a master alloy, a ribbon was made by a single roll method, which is a conventional method for preparing amorphous metal ribbon. The diameter of the copper roll was 300 mm, and the quartz tube was 10 mm Slit. The vacuum chamber pressure was 450 Torr and the He gas injection pressure was 0.05-0.07 Kgf / cm 2 to prepare a ribbon having a thickness of 20 mm and a thickness of 10 mm.

Fe기 비정질 합금을 이용한 출력용 코어의 직류중첩특성을 Mn-Zn 페라이트 코어와 비교한 결과 표 1과 같다. (언덕턱치스는 동일한 것으로 하고 비교전류에 따라 정리했다.)Table 1 shows the DC overlapping characteristics of the core for output using Fe-based amorphous alloys compared with Mn-Zn ferrite cores. (The hill thresholds are the same and arranged according to the comparison current.)

By reducing the iron loss by adding Ni and improving the soft magnetic property, it is possible to apply to high frequency inductance element and special device which has high performance and high durability by making low saturated magnetic flux density material. And contribute to lightening and shortening.
