At the 2020 Global 500 Unicorn Companies Conference held on December 2, QDYL Advanced Materials Technology Group entered the list of the Global 500 Unicorn Companies for the first time.
QDYL`s main products are new soft magnetic materials prepared with extreme manufacturing technology. At present, it has formed three series of products: amorphous alloy ribbons and products, micron spherical metal powders and products, and nanocrystalline ultra-thin ribbons and products. The products are widely used. In the fields of power distribution, new energy vehicles, wireless charging, nuclear power, medical and aerospace.
Among them, amorphous alloy ribbon is a national strategic energy-saving and environmentally-friendly new material. Since 2018, it has the largest market share in the world. It has been applied to 56 power grid companies worldwide and is widely used in "infrastructure" fields such as rail transit and data centers; The product's micron-level spherical metal powder has been used in well-known new energy vehicles such as Tesla; the product's nanocrystalline ultra-thin ribbon technology has reached the world's leading position. In 2020, it has successfully realized import substitution, and solves wireless charging for high-end smart phones such as Huawei and ZTE. Material supply, and solved the key material "bottleneck" problem in China's major scientific fields.
The production and sales of the amorphous industry rank first in the world
Amorphous alloy is called "metal glass" or "liquid metal", which has excellent magnetic conductivity, corrosion resistance, high temperature resistance and other properties. Amorphous alloy ribbon is one of the main forms of amorphous alloy. The molten steel is rapidly cooled at millions of degrees per second and formed into a thin strip with a thickness of only about 0.03 mm at one time.
As a world-recognized sustainable development strategic industry, the amorphous alloy industry is currently widely used in distribution transformers, which can reduce no-load loss by 70-80% compared with traditional transformers. It is a new energy-saving and environmentally-friendly material advocated by the country. The amorphous alloy industry involves multidisciplinary cross-penetration, and the technical entry barriers are high. Before the 20th century, amorphous alloy technology was monopolized in the hands of the United States, Japan and other countries. Since QDYL launched the amorphous alloy research and development project in 2008, it has been more than ten years A total of more than 800 million yuan has been invested to overcome difficulties and independent research and development, and completely realize the import substitution of amorphous materials. By 2018 and 2019, the production and sales of amorphous alloys have ranked first in the world.
The company's amorphous alloy ribbons are widely used in the field of power distribution, new infrastructure user engineering represented by subways and data centers. In the field of power distribution, the company serves 56 power grid companies worldwide and sells well in 13 countries and regions around the world. The company is guided by market demand and gradually expands its application in the field of new infrastructure users such as subways and data centers.
In addition, since 2018, the company has expanded from a material supplier of amorphous alloy strips to the downstream of the industrial chain, and has become a provider of comprehensive solutions for the amorphous transformer industry. In 2019, it developed and produced a new generation of high-performance and high-reliability amorphous three-dimensional wound core for the first time in 2019. The product's design process, intelligent manufacturing, and technical performance have reached the international leading level, which has led the transformation of the global distribution transformer industry.
Ultra-thin nanocrystals solve the national "technical bottleneck" problem
Nanocrystals mainly refer to iron-based nanocrystalline alloys, which are formed from iron, silicon, boron and a small amount of copper, niobium and other elements through a rapid solidification process to form an amorphous alloy, which is then properly annealed to form nanocrystalline and amorphous alloys. Material with mixed structure of crystal. Nanocrystalline materials are mainly used to make high-end common-mode inductors, high-frequency transformers, various current transformers, and high-end magnetic amplifiers. Related core devices are mainly used in new energy vehicle power management systems, drive systems, mobile phone wireless charging modules, rail transit, dust removal power supplies, photovoltaic power grid-connected inverters, digital electronic products, smart meters in the power grid, etc.
In the past, nanocrystalline materials with a thickness of less than 14 microns once became a "bottleneck" forbidden zone in China's high-end equipment manufacturing field. In 2019, the company made the nanocrystalline ultra-thin ribbon the thinnest and widest in the industry. In terms of thickness, QDYL broke through the mass production technology of nanocrystalline ultra-thin strips with a thickness of 14 microns for the first time in China, realizing import substitution; the width reached 150mm, achieving industry leadership. At the same time, QDYL pioneered the precision continuous casting production technology in China that can produce more than 3 tons of ultra-thin nanocrystals in a single continuous casting process, which can produce more than 3 tons of ultra-thin nanocrystals in a single continuous casting, which is much higher than the industry average.
Nanocrystallized ultra-thin strips
Magnetic powder has the world's most advanced production line
Magnetic metal powder is a powdery material obtained by crushing and atomizing a metal solution with process equipment such as a gas atomization device. It is usually used to make different types of magnetic cores. The magnetic core is one of the core components of inductive components. Magnetic powder The key characteristics such as the composition, purity and morphology of the magnetic core determine the performance of the magnetic core. Mainly used in home appliances, photovoltaics, communications, power supplies, new energy vehicles and other fields.
Broken powder and high-end atomized powder are the two major powder series products of QDYL. Among them, the sales volume of amorphous and nanocrystalline crushed powder has ranked first in the world. The superior performance characteristics of high-end aerosolized powder enable customers to have less performance fluctuations during use, and can provide customers with customized powders for special needs, and have the ability to jointly develop markets with customers.
The company independently developed the world's most advanced continuous casting gas atomized metal powder production line, which can achieve continuous production of 2 tons per shot, which is much higher than other domestic enterprises.
