Ultramicrocrystalline iron core manufacturers: Introducing the 'secret' of amorphous strip! -

Nanocrystalline magnetic core: the 'secret' of amorphous ribbon! What is Amorphous Ribbon? There are generally two kinds of materials that people touch in daily life: one is crystalline material and the other is amorphous material. The so-called crystalline material means that the arrangement of atoms inside the material follows certain rules. On the contrary, if the internal atoms are arranged in an irregular state, it is an amorphous material. In general metals, the internal atoms are arranged in an orderly manner, and they are all crystalline materials. Scientists have discovered that after metals are melted, the internal atoms are in an active state. Once the metal starts to cool, the atoms will gradually be arranged in an orderly manner according to a certain crystal state law as the temperature drops, forming a crystal. If the cooling process is fast, the atoms are condensed before they can be rearranged, thus producing amorphous alloys. It is a rapid solidification process that is used to prepare amorphous alloys. Spray high-temperature molten steel in a molten state onto a cooling roll rotating at high speed. The molten steel is rapidly cooled at a rate of one million degrees per second, and it takes only one thousandth of a second to lower the molten steel at 1300°C to below 200°C to form an amorphous strip. Primary characteristics of amorphous alloys 1. Amorphous alloys are composed of ferromagnetic elements (Fe, Ni, Co) and amorphous elements (Si, B, C); 2. Characteristics of amorphous alloys: low correction Coercive force, high magnetic permeability, low loss, low saturation magnetic induction, high resistivity, high temperature stability, excellent frequency characteristics and adjustable magnetic function; 3. After proper annealing, the iron-based non-wafer ( Belt) exhibits lower specific total loss than grain-oriented silicon steel sheet (belt). Use of Amorphous Ribbons. Compared with crystalline alloys, amorphous alloys have undergone significant changes in physical, chemical and mechanical functions. Taking the amorphous alloy mainly composed of iron as an example, it has the characteristics of high saturation magnetic induction and low loss. Due to such characteristics, amorphous alloy materials have a wide application space in many fields such as electronics, aviation, aerospace, machinery, and microelectronics. For example, in the aerospace field, it can reduce the weight of power supply and equipment, and increase the payload. Used in civilian electric power and electronic equipment, it can greatly reduce the size of the power supply, improve efficiency, and enhance anti-interference ability. Miniature iron cores can be widely used in transformers in ISDN. Amorphous strips are used to make sensor tags for anti-theft systems in supermarkets and libraries. Amorphous alloys have magical effects and have broad market prospects. At present, with the development of electronic technology in the direction of high frequency and miniaturization, amorphous ultrafine crystal soft magnetic alloy materials have been made into various magnetic devices to replace silicon steel, ferrite and permalloy for use in the power industry and electronics industry And in the field of power electronics technology, used as transformers, reactors, filters, transformers, and sensors for current transformers, high-power switching power supplies, inverter power supplies, and program-controlled switch power supplies.
