September 17 main forum

-- Macro development of automobile industry

Opening of the conference & speech by leaders

The summit was delivered by Zhao Jiasheng, vice president of China Nonferrous Metals Industry Association, Jiang Wei, director of the New Materials Department of Shanghai Economic and Information Commission, on behalf of Zhang Jianming, vice director of Shanghai Nonferrous Metals Industry Association, Xu Ming, director of Shanghai Nonferrous Metals Industry Association, and Fan Xin, CEO of Shanghai Nonferrous Network Information Technology Co., Ltd.

Liu Qiuli, secretary-general of Shanghai Nonferrous Metals Industry Association, chaired the meeting on the spot.

Zhao Jiasheng, vice president of China Nonferrous Metals Industry Association, delivered a speech:

Since the epidemic, various industries have encountered unprecedented difficulties. Under the leadership of State President Comrade Xi Jinping at the core, China has actively and orderly promoted the resumption of work and production. In the first seven months, China's non-ferrous metals industry has shown a trend of recovery and improvement, mainly reflected in the overall steady growth of smelting output of commonly used non-ferrous metals, the positive growth of mining and processing output, and the further reduction of investment in fixed assets. The profits of enterprises have continued to increase in a single month, the cumulative decline in profits has narrowed significantly, and the prices of copper, aluminum, lead and zinc in the domestic market have basically returned to their pre-epidemic levels.

With the transformation and upgrading of the automotive industry and the gradual development to the direction of new energy, lightweight, intelligence and network connection, non-ferrous materials including aluminum, copper, magnesium, holmium, nickel, cobalt, lithium and so on are more and more widely used in the automotive field. Aluminum is the representative material to realize the lightweight of automobile. in recent years, with the gradual acceleration of the lightweight process of automobile, the amount of aluminum used in automobile structures and panels of domestic models began to increase. According to the statistics of relevant departments, including vehicle manufacturing and auto parts export, the total aluminum consumption of China's automobile manufacturing industry is 5.935 million tons in 2011, with a compound annual growth rate of 12% from 2019 to 2019. Although domestic passenger car production has declined this year due to the impact of the epidemic, with the increase in the amount of aluminum used per unit of cars, the increase in the output of commercial vehicles and the growth of aluminum demand in the domestic auto parts market, it is estimated that this year's aluminum consumption in China's automobile industry will reach 6 million tons, basically the same as last year.

In addition to aluminum, other metal materials have also attracted much attention in the automobile manufacturing industry, such as magnesium alloy materials and lithium cathode materials. At present, the average amount of magnesium used by fuel vehicles in China is 1.5 kg, and that of new energy vehicles is 20 kg. With the continuous application of magnesium alloy materials in automobile lightweight, magnesium alloy materials will have a lot of room for development in the future. In addition, as the core component of new energy vehicles, lithium battery has driven the rapid development of the whole lithium industry. Lithium cathode materials, connected with mineral raw materials, batteries and automobiles, is an important link in the development of non-ferrous metals industry from raw materials to deep processing, and is the top priority of China's development strategy of emerging industries.

Although the development of the non-ferrous metal industry has promoted the transformation and upgrading of the automobile industry, and the development of the automobile industry has promoted the improvement of the quality and efficiency of the related industries of non-ferrous metal materials, on the whole, at present, the level of research and application of non-ferrous metal materials in China can not fully meet the needs of the rapid development of automobile and other industries. Structural problems such as lack of technological innovation capacity, overcapacity of low-end products, unstable product quality and relatively backward application and development still exist. In this regard, he suggested that the whole industry should correctly understand the guiding role of industrial policy, put technological innovation in a prominent position, actively promote industrial restructuring, and strive to create a good market environment.

Jiang Wei, Director of New Materials Department of Shanghai Economic and Information Commission, delivered a speech:

Driven by a new round of scientific and technological revolution and industrial reform, intelligence, electrification, networking and sharing are increasingly becoming a new trend in the development of the automotive industry. New trends and new changes also promote the innovation and reform of the automobile industry in many aspects, such as technology, materials, products, formats, models and so on.

Material is the basis of the transformation and upgrading of the automobile industry and an important part of automobile innovation. The development of automotive material technology is closely related to the mastery of automotive core key technologies. However, at present, there is a big gap between China's automobile industry and the international advanced level in key material research and development, advanced processing industry, etc., which seriously restricts the transformation, upgrading, enlargement and strengthening of China's automobile industry, and the development pace of becoming a powerful country in the automobile industry. there is an urgent need to speed up the innovation, integration, opening and cooperation between the material industry and the automobile industry, and speed up the research and development of automotive materials and their application in automobiles. Thus help the automotive industry transformation and upgrading and bigger and stronger, to achieve high-quality development.

The automobile industry is an important pillar industry in Shanghai, which has gathered to form a complete industrial chain, attracting more and more automobile and spare parts enterprises to settle in Shanghai. Shanghai automobile industry is speeding up the innovation transformation and promoting the construction of new energy vehicles and intelligent network connection automobile high-end manufacturing industry cluster. Promoting the research, development and application of new automotive materials in Shanghai will strongly recommend the integrated and innovative development of the materials industry and the automotive industry, and promote the establishment of advanced new energy automobile industry clusters.

What China wants to take is the interaction between the application side and the supply side, because Chinese materials are not complete and need to be further improved, and there is still a big gap between China and foreign countries for the further application of new materials.

Xu Ming, director of Shanghai Nonferrous Metals Industry Association, delivered a speech:

Material is the basis of the transformation and upgrading of the automobile industry and an important part of automobile innovation. The development of automotive material technology is closely related to the mastery of automotive core key technologies. But at present, there is a certain gap between China's automobile industry and the international advanced level in the key material research and development, advanced processing industry and so on. There is an urgent need to speed up the innovation, integration and open cooperation between the material industry and the automobile industry, and speed up the research and development of automotive materials and their application in the automobile, so as to promote the transformation, upgrading and strengthening of the automobile industry, and achieve high-quality development.

In order to promote the deep connection between the new material industry and the automobile and spare parts industry, the second selection activity of casting products, which has the most potential for automobile materials in 2020, was officially launched in May this year. This activity received a positive response from industry enterprises, with a total of 157 new material products submitted by 124 enterprises. finally, 38 award-winning enterprises were judged by experts from 14 automobile companies, such as SAIC passenger cars, Dongfeng, BYD and spare parts assembly enterprises. The award-winning enterprises will conduct in-depth exchanges with automobile and spare parts enterprises during this forum to jointly promote the integrated development of new materials and automobile industry.

The forum is rich in content and various forms. The meeting specially invited Shi Jianhua, Deputy Secretary General of China Automobile Industry Association, Dr. Guo Lei, New Energy vehicle Propulsion Office of Shanghai Economic and Information Commission, and Cui Dongshu, Secretary General of National passenger car Market Information Association. And leaders and experts from the upper and lower reaches of the automotive industry chain, such as SAIC, Aichi, Chinalco, Liaoning Zhongwang, Jiangsu Dingsheng, Ningbo Bowei, Jiaotong University, Suzhou University, government departments, scientific research institutes, experts focus on the latest development trend of the automotive industry, the application prospect and demand of materials in the automotive field, the development direction of the latest technology and other hot issues. I believe that the in-depth interaction between upstream and downstream and the wonderful speeches of the guests will be of great help and benefit to all of you.

Topic: development of aluminum brazing pipe material for high temperature intercooler

Speaker: nie Cunzhu, head of aluminum alloy research office of Shanghai Huafeng material Science and Technology Research Institute, Doctor of Engineering.

Nie Cunzhu said that the rare earth element Ce can purify the grain boundaries of the alloy, promote the precipitation of the strengthened phase in the Al-Cu alloy, and improve the aging strength of the alloy. The addition of trace Sn element can obviously shorten the time for aging to reach the peak strength.

High temperature homogenization treatment can reduce the segregation of solute elements at grain boundaries and promote the dissolution of coarse second phase, which is beneficial to the precipitation of strengthening phase in the aging process. Homogenization treatment not only includes the effect of high temperature homogenization, but also can realize the interaction between Al3Zr phase and low temperature strengthening phase (θ'/ θ'), form a stable microstructure and effectively improve the high temperature strength of the alloy.

[expert practical information] the development of high temperature and high strength aluminum alloy tube sheet is the general trend of demand and production technology must be mastered!

Parallel forum 2muri-extruded aluminum alloy special show

Topic: application of high-end aluminum profiles in new energy vehicles

Speaker: sun Wei, Deputy General Manager of Research and Development Institute / Group of Liaoning Zhongwang Group Co., Ltd.

In the future, with the development of lightweight, the market share of new energy vehicles will gradually increase, and the use of aluminum alloy will also increase, in which the proportion of extruded materials mainly used for battery packs and car bodies will also increase, and the proportion of extruded materials is expected to reach more than 15% by 2030. The application of aluminum alloy in new energy vehicles has many advantages, such as reducing weight, improving mileage, improving vehicle mobility and maneuverability, stable, shock absorption, easy recovery and so on. In terms of energy consumption, for every 10% reduction in car weight, fuel efficiency can be increased by 6%, mileage can be increased by 13.5%, and 100 km acceleration time can be reduced by 5%.

[automobile Summit] Application and Development trend of Aluminum Profiles in New Energy vehicles

Topic: aluminum alloy extruded profiles for vehicles and their application cases

Speaker: Li Jianxiang, Chairman of Guangdong Hesheng Industrial Aluminum Co., Ltd.

The performance requirements of automotive aluminum alloy profiles are as follows: first, it has appropriate strength and stiffness, second, it has good fatigue resistance, third, corrosion resistance, fourth, weldability, and fifth, examples of special requirements.

Generally speaking, most of the automotive materials choose medium strength or medium to high 6 series alloys, and some low grade 7 series alloys. Properly distinguish and select materials according to the use of the product. However, we can not always choose the best alloy according to the demand of aluminum for car body, because some materials may not be extruded to meet the conditions of industrial mass production. This is mainly based on two factors: alloy extrudability and quenching sensitivity.

[automotive Summit] Automotive aluminum alloy material performance requirements, material selection, process these do not understand the OUT!

Topic: present situation and Development trend of Intelligent Manufacturing of Aluminum Extrusion equipment

Speaker: Lin Kaichao, Chairman of Nanhai Wangeshi Machinery and equipment Co., Ltd., Foshan City.

The current situation of aluminum extrusion equipment industry is that the United States, Britain, Germany, Italy and other countries are still the most advanced countries in aluminum extrusion equipment technology; aluminum extrusion equipment design and aluminum die manufacturing are more closely integrated; now we pay more attention to the consistent operation of different parts and processes of the whole production line. The country with the largest number of large extruders in the world; aluminum extrusion equipment designed and manufactured by itself and has more independent intellectual property rights; equipment control accuracy such as isothermal, homogenization, efficiency, consumption reduction and so on need to be improved.

There are four main points in the trend prospect of aluminum extrusion equipment: continuous overcoming of large-scale and heavy problems; big data and cloud computing to achieve remote control and diagnosis; intelligent production of the whole line, which can be operated by only 3-4 people; and the application of 5G technology. the formation of the Internet of things.

[automobile Summit] Chairman's guidance: a brief history of the development of aluminum extrusion equipment, industry status, opportunities and trends

Topic: study on long order pricing and hedging of spot Raw Materials of Aluminum Extruded Materials of China

Speaker: Liu Xiaolei, Director of Big data Department of Shanghai Nonferrous Network Information Technology Co., Ltd.

SMM believes that the overall supply of electrolytic aluminum continued to maintain an upward trend in the second half of the year, the recovery of domestic aluminum consumption in the "post-epidemic phase" was stronger than expected, and the recovery process of overall consumption slowed down in the fourth quarter.

In terms of domestic inventory, the risk of electrolytic aluminum accumulation during the year is relatively small, and it is still possible to remove the inventory in the fourth quarter. On the one hand, although the new production capacity is on the rise, the overall output increment is relatively slow; the supply side of the original import window intermittently closed in the fourth quarter limited the scale of imported aluminum ingots; On the other hand, downstream consumption can still be expected. Aluminum processing consumption from October to December is expected to rise steadily, with annual consumption expected to be more than 3%. In particular, terminal sectors such as domestic construction, transportation, and durable goods have led to the pick-up of primary aluminum consumption, and make up for the gap caused by the decline in domestic aluminum exports.

Paying attention to the reversal of three conditions: the reversal of the internal and external ratio, the reversal of the domestic futures basis structure, and the reversal of the spot-to-futures upside structure will determine the main contradiction for the enterprise to enter the hedging cycle. In the short term, the above reversal conditions are still not available when the inventory is less than 1 million tons, and the actual reversal needs to pay attention to the point opportunity after the formation of the mismatch cycle of consumption and aluminum ingot supply.

[automobile Summit] study on long order pricing and hedging of spot Raw Materials of SMM: China Aluminum Extruded Materials

Parallel Forum 3muri-Special event of Nonferrous Foundry

Topic: development and Application of New High strength and toughness cast Aluminum Alloy

Speaker: Zhang Hai Suzhou University

Zhang Hai pointed out that it is imperative to protect the environment and alleviate the energy crisis > to save energy and reduce emissions, to develop new energy vehicles (mileage anxiety), and to lighten the weight of cars. For every 100Kg reduction in pure new energy vehicles, mileage can be increased by 10% Mur11%, battery costs can be reduced by 20%, and daily wear and tear costs can be reduced by 20%. However, lightweight needs to be carried out on the premise of ensuring the safety and carrying capacity of the car, and control the cost-the difficulty is!

Zhang Hai pointed out that attention should be paid to the composition optimization and modification of existing high strength and toughness cast aluminum alloys. The main ideas for the development of new cast aluminum alloys for high strength and toughness structures without increasing cost are: microalloying, heat treatment, etc.; expanding the application of high strength and toughness aluminum alloys in automotive and other fields; with regard to the research and development of new production processes, Zhang Hai said that the key is to explore new processes and new methods to improve the product composition uniformity, microstructure density, grain refinement and other factors to increase strength and toughness; the development of new production equipment.

Development and Application of New cast Aluminum Alloy with High strength and toughness

Topic: TCB Crystal seed Alloy and its Application Technology in Automotive Aluminum Alloy

Speaker: Liu Xiangfa Shandong University

UHS aluminum alloy (abbreviated as high-strength and ultra-high-strength aluminum alloy, including Zn, Zr, Si, Cu, Mg, Cr, V, etc.) has a broad application prospect in aerospace, transportation, national defense and 5G communications because of its strength advantages. However, the poor plasticity and toughness and processability have become the bottleneck restricting its development.

Based on the close combination of industry, university and research, starting from revealing the mechanism of nucleation poisoning and turning the evolution of molten clusters into a breakthrough, TCB crystal seed alloy was invented and developed, the direct nucleation of crystal seed was realized, the source of poisoning was eliminated, and the fine grain strengthening of aluminum alloy was realized stably. After 17 years of technical research, a poison-resistant crystal seed alloy containing high temperature stable core-shell TCB has been developed.

The advantage of anti-poisoning TCB crystal seed alloy is obvious, which can solve the poisoning problem of grain refinement, solve the problems such as hot cracking and shrinkage, solve the contradiction between grain refinement and improving electrical conductivity and thermal conductivity, and the application cost of TCB technology is low.

To sum up, TCB is not only a "super seed refiner", but also a new seed technology to enhance the added value of aluminum alloy products. It is a "golden key" and a powerful "grip" to open the research and development of new aluminum alloy materials and processing technologies.

[automobile Summit] the application prospect of high-strength and ultra-high-strength aluminum alloy is broad, but there are technical bottlenecks to discuss in detail the application of TCB crystal seed alloy.

Topic: research on the Application of New Aluminum Alloy Materials in chassis parts of New Energy vehicles

Speaker: Zhonggu Chinalco Suzhou Research Institute

Zhong Gu said that more than 600 aluminum parts are used in systems such as body, chassis, power and transmission. The amount of aluminum used for automobile in all countries / regions shows a rapid growth, especially in North America and China. Aluminum is mainly used in car body structural parts, wheels, body panels, transmission system, cylinder block and cylinder head; the amount of aluminum used in class C and above is much more than that of An and B class cars. Comparison of types of aluminum for automobile at home and abroad: aluminum for castings accounts for more than 60%, and the proportion of aluminum sheet is increasing year by year, especially for C-class and above models.

At present, the aluminized lightweight effect of the chassis parts is obvious, and the vehicle performance is improved significantly. The aluminization rate is high abroad, which is much lower at home than abroad. It is mainly used in high-end self-brand cars and pure electric cars, but the permeability is only about 10%. The steering knuckle product has the highest permeability in the chassis and the most technically difficult part is the subframe. The finished product rate is low, the dimensional accuracy needs to be improved, and the welding joint performance and welding deformation control level are low.

Structural parts pay great attention to lightweight efficiency, and the design of lighter parts, the development of higher performance materials, higher production efficiency and finished product rate are the main trends in the future.
