Amorphous strip (sheet) equipment need to know the matter
This coincides with the future planning. In the future, we will adhere to the R & D and production of high-end, high-quality and characteristic amorphous and nanocrystalline strip products, and actively expand its application in motor, consumer electronics, new energy vehicles, smart home and other fields.
China's amorphous strip developed relatively late. In December 1995, it was established. In 2010, China built a production base with an annual output of 40000 tons of iron-based amorphous strip, breaking the foreign monopoly and becoming the second country with amorphous strip industrial technology.
With the promotion of the upgrading and transformation project of the State Grid, it is mainly used in the amorphous strip of distribution transformers, and the market is hot between 2014 and 2018. In the meantime, products were once in short supply, and amorphous strips alone were on 7 production lines, with annual revenue exceeding 0.2 billion.
Amorphous alloys can be manufactured into bulk amorphous materials with good mechanical and physical properties, but due to technical problems, mass production is difficult. At present, amorphous alloys are mainly used as soft magnetic materials for the production of transformer cores, and the products are mainly amorphous strips.
Amorphous alloy as a soft magnetic material, mainly used in the production of transformer core, the product is mainly amorphous strip. China's amorphous strip started late, but later catch up. At present, the domestic basic realization of amorphous alloy industry full coverage, overseas competitors are mainly Japan and. The global and domestic market share of domestic companies has been equally significant. This overall reflects that domestic enterprises have basically achieved independent control in the field of amorphous alloy strips and have a share in the international market.
In terms of development status, it is introduced that since the beginning of this year, the development of iron-based amorphous industry has shown the characteristics of increasing production efforts of strip enterprises, increasing market space for amorphous three-dimensional coils, and obvious achievements in the development of new markets for amorphous transformers. The Secretary-General and Deputy Secretary-General introduced the development status of magnetic material standards, and other national standards have been declared.
In terms of basic research, the associate professor shared the research on the effect of surface flattening on the properties of iron (cobalt)-based amorphous strip soft magnetic alloys. The assistant general manager introduced the company's research progress in super-tough amorphous solid coil special materials, ultra-low loss amorphous materials and high saturation amorphous materials. Associate professor and deputy director shared the research on ultra-fine amorphous soft magnetic composite materials.
Until the second half of 2021, with the target promotion and the implementation of the transformer energy efficiency improvement plan, the policy transmission effect appears, the amorphous strip industry also significantly recovered.
