This morning, the 2018 National Science and Technology Awards were announced in Beijing, and a total of 285 projects (candidates) were selected. Among them, the "Application and Development and Engineering of Domestic Amorphous Strip in Power System" project won the second prize of the National Science and Technology Progress Award.
Amorphous alloys refer to metals and alloys in which there is no long-range order in the internal atomic arrangement. Traditional metals or alloys have a regular crystalline structure, while amorphous alloys break the original regular crystalline structure. Under rapid cooling, they exhibit a long-range disordered structure, which is very similar in structure to our common liquids. .
Iron-based amorphous alloy is a type of amorphous alloy widely used in transformers. Its iron loss rate is one-fifth that of traditional silicon steel materials. It can save 60-70% of energy consumption by replacing traditional silicon steel as a distribution transformer. It is well deserved. Energy-saving materials.
Amorphous alloy not only has a lower loss rate than traditional silicon steel, but also has a much shorter manufacturing process compared to silicon steel in terms of process flow, which greatly reduces the cost of preparation.
Beginning in the 1980s, China's research and development of amorphous strips has been listed as the focus. For China in the 1980s, amorphous materials are just a new type of material that has been "heard of but never seen." Coupled with the overall blockade of amorphous core technology abroad, research and development work is extremely difficult.
Origin of Chinese amorphous alloy materials
At the planning meeting of the Ministry of Metallurgy in 1975, Professor Ke Cheng took a sample of the amorphous ribbon donated by the United States, which caused a heated discussion among the participants. This is the first time that the Chinese have seen this new material and it is also the Chinese amorphous industry. Enlightenment.
Ma Hongliang, former deputy director of the Institute of Iron and Steel Research, talked about the difficulties of amorphous research
The development of amorphous has also taken the fast track of the development of the times, and the 100-ton and 1,000-ton production lines have been gradually completed. A number of outstanding amorphous manufacturing enterprises have emerged.
China's amorphous industry has grown from scratch until it has become an amorphous power. In just a few decades, the solidarity and cooperation of upstream and downstream enterprises cannot be separated.
Among them, the establishment and operation of the National Amorphous Energy-Saving Material Industry Technology Innovation Strategic Alliance will meet the needs of China's power system development and energy-saving emission reduction for amorphous alloy materials and products, and enhance the independent innovation capability and core competition of the amorphous energy-saving material industry chain. Power and breaking the long-term monopoly of developed countries is of great significance.
