Further carry out in-depth school-enterprise cooperation relations such as school-enterprise talent sharing, technology sharing and school-enterprise management in the field of amorphous alloys, and comprehensively improve the school-running ability and the market competitiveness and social influence of enterprises.
Third, three years specific goals
(1) Research and development and project initiation purposes and functions:
1) 10,000-ton high efficiency and energy saving Fe-based amorphous ribbon production line development
China's Fe-based amorphous alloy ribbon industry has developed rapidly, with an annual designed production capacity of nearly 300,000 tons, and is the world's ****** producer. The formation of leading domestic enterprises to lead, a number of enterprises into a parallel pattern. On November 26, 2021, Qingdao Yunlu Advanced Material Technology Co., Ltd. was successfully listed on the Science and Technology Innovation Board, which was the first central enterprise "Science and Technology Reform Demonstration Action" enterprise to land on the science and Technology Innovation Board in China, and also the first listed enterprise after the establishment of China Aviation Development. Since its establishment, the company has been focusing on the field of advanced magnetic metal materials, and has formed three major materials and product series of amorphous alloy, nanocrystalline alloy and magnetic alloy powder, among which, the annual design capacity of Fe-based amorphous has reached 60,000 tons, becoming a global ****** amorphous alloy ribbon manufacturing enterprise. In addition, Jiangsu Guoneng, Zhejiang Zhaojing, Antai Technology, Zhongyue amorphous, etc. have an annual production capacity of more than 20,000 tons, and the total domestic production capacity does not exceed 80,000 tons.
From October 2021, the material price of domestic Fe-based amorphous ribbon has been soaring. The price of the main raw material iron boron has risen from 21,500 yuan/ton to 25,000 yuan/ton, pure iron rose from 6022.9 yuan/ton to 6976.9 yuan/ton, domestic silicon metal 441 rose from 13805 yuan/ton to 23878 yuan/ton, domestic silicon metal 553 rose from 6466 yuan/ton to 21878 yuan/ton. With the increase in demand, the price of Fe-base ribbon material showed a small pace of fast running, only three months, the price of amorphous ribbon from the original 13-14 yuan per kilogram, up to 17-18 yuan per kilogram, some Fe-based amorphous alloy companies gradually out of the dilemma due to increased profits. We found that although the price of amorphous ribbon increased by as much as 30%, the overall price. The increase is still lower than silicon steel. In this way, in the process of designing a transformer with the same capacity and model and the same energy consumption level, the cost of Fe-based amorphous is lower than that of silicon steel, the competitive advantage is Clearly, Fe-based amorphous ribbon has once again become the focus of the transformer industry.
At present, there are 12 domestic Fe-based amorphous ribbon enterprises, 35 production lines, designed production capacity of 300,000 tons, but because most of the technical process, product quality is not up to standard, production equipment technology aging, there is no stable and consistent production capacity, so 8 of the amorphous production enterprises are shut down and out of business. By the end of December 2021, the four domestic enterprises that can stabilize production have a total of 10 production lines, with a theoretical capacity of 80,000 tons, and the industrial recovery trend is obvious. China has about 17 million transformers in operation on the network, with a total capacity of about 11 billion kVA. Transformer loss accounts for about 41% of the power loss of transmission and distribution, amorphous transformers in the power industry has greater energy saving potential, the main market is still the power industry. On February 23 this year, "People's Daily" published a signed article by Xin Baoan, chairman of the State Grid Co., LTD., and secretary of the Party Group, "Resolutely shoulder the responsibility of the power grid and actively promote carbon to peak carbon and peace." The article pointed out that after the Party Central Committee proposed the "double carbon" goal, the State Grid Company implemented it in the first time, issued the implementation of the first "double carbon" action plan and the construction of a new power system action plan for domestic enterprises, and introduced a series of pragmatic measures to strive to be the promoter, pioneer and leader of the energy revolution. The China Electrical Appliance Industry Association Amorphous Materials Application Branch has calculated that amorphous transformers in the field of national grid and southern grid transformer may gradually increase to 40% or even 45% in 2-3 years.
Some professionals have analyzed that the Fe-based amorphous alloy ribbon industry chain will increase in a certain proportion under the background of "double carbon". It is expected that in 2022, the domestic Fe-based amorphous ribbon will once again exceed 100,000 tons, which is once again after 2016. Unlike in the past, after increasing to 100,000 tons this time, production will not fall off a cliff as it did in 2018, and there is expected to be a stable growth room between 2022 and 2030. By the end of the 14th Five-Year Plan, all types of transformers are expected to demand 150-180,000 tons of Fe-based amorphous ribbons, and the market gap in the next 2 to 3 years is between 50,000 and 80,000 tons.
In this favorable window, Jiangsu Guoneng trial seize the potential, starting from the beginning of February this year, the project, the "10,000-ton amorphous ribbon line 4", the previous 3 after 6 years of continuous exploration, innovation, technical transformation experience, accumulated and declared 8 core patents, on this basis, to upgrade the key components of the production line: "efficient crystallizer", "high-speed double receiving device", "a Three core innovative key components, such as the intelligent adjustment device, have been increased from the original 6,000 tons/year to 10,000 tons/year, and product quality and consistency, stability, and operability have been greater. At present, the board of directors of the project company has passed the approval, and the technical path, parameter setting, device promotion, drawing confirmation and other work will be completed within the year, and the bidding information will be released at the end of the year, and the equipment manufacturers with complete equipment, production capacity, confidentiality norms and quality control capabilities will be selected.
2) National level energy efficiency amorphous three-dimensional coil core transformer
Amorphous ribbon three-dimensional coil core has been recognized by the market in recent years. Compared with conventional amorphous core, its structure improves the noise of traditional flat core, adopts a unique coil support structure, strengthens the short circuit tolerance of amorphous core dry type transformer, and improves the safety and reliability. At present, the State Grid and the Southern Power Grid have also included the three-dimensional coil core transformer in the new technology catalog.
In the past two years, in the transformer bidding of the State Grid, the three-dimensional coil core transformer has reached nearly 50,000 units, accounting for about 8% of the total purchase. In addition to distribution networks, three-dimensional coil amorphous transformers have strong potential competitiveness in data centers, wind power, solar energy, new energy vehicle charging stations, rail transit, and ship transformers. Starting from November 2021, the amorphous three-dimensional coil core market demand has soared, and the price has risen significantly. Three-dimensional coil amorphous core manufacturing is affected by the ribbon process, the process is complex, the processing efficiency is not high, the supply phenomenon is in short supply, the price is soaring, some enterprises three-dimensional coil core price the highest offer of 30-32 yuan per kilogram.
In the next three years, the company will be amorphous alloy three-dimensional coil core oil immersed distribution transformer research and development as a new development project, the key indicators to achieve the product no-load loss ratio GB20052-2020(power transformer energy efficiency limit value and energy efficiency grade) energy efficiency level 1 standard decreased by 10%; The error degree of circular iron core column is less than 6, the utilization rate of iron core ribbon is greater than 90%, and the 24-hour rated capacity of complete equipment is 30 tons; It is expected to produce more than 5 patents.
In view of the technical difficulties existing in amorphous vertical wound iron core transformer, there are mainly several breakthroughs, design a rotating winding bracket cylinder; Amorphous vertical wound iron core column outer round, using elastic polyurethane potting; Polyurethane damping resin is used to reduce the vibration and noise transmission of iron core and coil. Different widths of ribbon are used for diagonal symmetric rolling and reverse winding to improve the utilization rate of ribbon.
