New Yellow River Reporter: Huang Min

A thin non -crystal belt, tearing it with a hand with a torn. In fact, a thin film of less than 0.03mm can carry a weight of nearly one ton. This seemingly ordinary material contains the energy. On July 13, the "five -year breakthrough" key project observation activities of the new and old kinetic energy in Shandong Province walked into the AVIC Magnetic Material Industrial Park located in Jimo District, Qingdao Jimo District. New Yellow River reporter was informed that the project produced the three most advanced soft magnetic materials in the world, and built the world's most advanced amorphous thin belt and nanocrystalline production line. It is the first "dual -carbon soft magnetic industrial park "It is a model for technology -driven high -quality development.

Cooling from more than 1600 ° C to 100 ° C within 1/2500 seconds, and the non -crystal vacuum loss energy consumption is nearly 80%.

On July 13th, the reporter came to the production site of the magnetic alloy powder powder production site of AVIC Magnetic Materials Industrial Park. It has the most advanced vacuum atomized magot alloy powder production line in China. Device; Tesla electric vehicle electrical control system OBC charging board is a typical application of the product. It is reported that all production equipment and processes in the park are independently developed by Yunlu shares and have completely independent intellectual property rights.

"It has only been 7 years since the development of atomized powder. It has been developed to 4th generation technology. In the future, we will go through further research and development iteration to make the powder accumulation technology required for high -performance alloy powder steel and 3D printing." Qingdao Yun Road Advanced Materials Technology Technology Technology Technology Technology Technology The relevant person in charge of the shares (hereinafter referred to as "Yunlu Co., Ltd.") said.

In the exhibition hall not far from the production line, a ring of about half meters stands, and it is still hot. This is the product produced by the world's most advanced amorphous alloy thinner production lines created by Yun Road.

"This is a ring piece created by amorphous belt materials. It is produced quickly to cool to 100 ° C in 1/2500 seconds." Thermal process control, thanks to the full set of production equipment independently developed by Yunlu Co., Ltd., the equipment can achieve a tonnage -level single -furnace output, far exceeding domestic counterparts.

Such extreme manufacturing technology is the "mother -based" of the birth of the soft magnetic material of the industrial park. Regarding this extreme manufacturing technology, the person in charge of Yunlu gave a more vivid saying -in the northeast at minus 40 ° C in winter, the hot water at 100 ° C in the sky is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s, and the cooling speed is 1000 ° C/s. The cooling speed of the amorphous band is 1 million ° C/s, and the one is only about 0.03mm of thin bands at a time, and the thickness is similar to the hair. Due to this supersonic cooling speed, the metal atom is frozen before finding the order of arrangement. Therefore, the amorphous material is liquid under a microscope, which is also known as "liquid metal" or "metal glass". It can be easily torn away by hand, but it is the most powerful metal material found to date. A thin film of less than 0.03mm can carry nearly one ton of weight. It has excellent magnetic conductivity, corrosion resistance, high temperature resistance resistance The performance is currently the most energy -saving power assembly transformer, which is nearly 80%of the energy saving of energy than silicon steel.

"For example, the air load loss of amorphous transformers is 60%-80%lower than the traditional transformer. Assuming a transformer of the same capacity, the traditional one-hour empty load requires 100 degrees of electricity, and the non-crystal is only 20-30 degrees." This is responsible for responsibility People say that non -crystal materials are energy -saving products for all life cycles and can be recycled.

"Nano -crystal Alloy" is one of the most advanced soft magnetic materials in the world, and it is also the third main product of AVIC Magnetic Material Industrial Park.

"At present, many high -end intelligent wearables, mobile phones and other brands of wireless charging materials have been used in cloud road nano crystals. Nano -crystals can accelerate particles to 0.7 times the speed of light. The person in charge said that nano -crystals are an inevitable choice under high frequency, miniaturization, and high efficiency trend of electronic products.

After more than ten years, it has broken through the industrialization of amorphous materials, and has produced the first in the world for 3 consecutive years.

During the interview, a reporter from Xinhuanghe learned that as a preferred project of the new and old kinetic energy conversion in Shandong Province in 2018, the AVIC Magnetic Material Industrial Park, which was invested in the investment and construction of Yunlu, invested 100 million yuan and covers an area of ​​90 acres. In March 2019, Construction construction will reach a full production state in 2023.

It was only more than a year after birth, and the driving effect of the industrial park was significant. From 2018 to 2020, the scale of Yunlu's business was 720 million. With the production park's production, sales in 2021 climbed to 940 million yuan, and the development speed was evident.

Behind the high -speed development, the thrust of scientific and technological innovation is indispensable.

The person in charge of Yunlu Technology told Xinhuanghe reporters that accelerators used a variety of products such as ultra -thin nano -crystal belt to break foreign technology blockade, solved the long -term "card neck" problem in the accelerator field, and realized domestic replacement. In particular, the amorphous industry has run out of "acceleration".

It is understood that the amorphous industry involves multi -disciplinary cross -penetration, and the threshold for technological entry is high. Under the 20th century, amorphous technology monopolies in the hands of the United States, Japan and other countries. Before cutting into the field of soft magnetic materials, Yun Road has achieved import substitutions for electromagnetic equipment such as Chinese microwave oven and frequency frequency air conditioners, and has ranked first in the country in the field of core magnetic devices for more than 10 consecutive years. In 2008, after realizing that the material was the "stuck neck" problem of the national magnetic device, Yun Road started the research and development of the "non -crystal alloy thin belt". In the background of the industry without ready -made models and experience, scientific research technology forces and R & D conditions are extremely lacking, Yun Road has invested hundreds of millions of dollars after more than ten years, and invested 500 million yuan from 2008 to 2013. After more than 1,400 days and nights The unremitting efforts finally realized the industrialization of the non -crystal alloy thin belt, and solved the problem of material import substitution. Since 2018, the non -crystal belt production produced by Yun Road has ranked first in the world for many years, becoming the "unicorn" of the amorphous industry, and comprehensively surpassed the former industry leading enterprises.

"In the 5 years we are very confused, our firm beliefs, scientific methods, and effective organizations help us continue to move forward. At that time, the chairman took us all the members to sort out the knowledge system and bought a lot of Qian Xuesen's" Aerodynamics "and sorted out the sorting out. The technical sequence and knowledge series of the product. We have done countless experiments, and the technical information is nearly 200G. "The person in charge of the technology said.

Today, under the national dual -carbon strategy, high -energy -efficient transformers represented by non -crystal have ushered in huge development air outlets. As of now, Yun Road has produced a total of 300,000 tons of amorphous belt materials. These materials can be reduced by nearly 2 million tons of carbon dioxide than traditional materials in one year, which is equivalent to building 1/2 of Paris area of ​​green space every year.

Thanks to scientific and technological innovation, the three major products of magnetic alloy powder, amorphous belt materials, and nano -crystals developed by Yun Road competed. AVIC's magnetic industrial park ushered in high -speed development. Base; built the nation's first magnetic alloy powder and device vertical factories. These most advanced soft magnetic magnetic magnetic magnetisms have been widely used in power distribution, new energy vehicles, new infrastructure, rail transit, consumer electronics, white home appliances, accelerators and other fields.

"Thanks to the continuous cultivation, the thrust of scientific research and innovation, and the tension of market applications have allowed our companies to develop rapidly." The person in charge of the technology said.
