Developing new energy vehicles is the trend
In recent years, the environmental protection requirements faced by the automotive industry have become increasingly demanding. Traditional vehicles have been referred to as one of the major sources of pollution in the urban atmosphere. It is imperative to control automobile exhaust. In this case, the development of new energy vehicles has become the choice of many auto companies. China has also issued a number of related policies to promote the development and use of new energy vehicles. For example, in the Notice of the Ministry of Industry, the Ministry of Finance, the Ministry of Science and Technology, and the National Development and Reform Commission on September 17th, the "Notice on Continued Promotion and Application of New Energy Vehicles" will be pure electric vehicles, plug-in hybrid vehicles and fuel cells. Cars are included in the scope of central financial subsidies. According to this notice, megacities or urban agglomerations with higher enthusiasm will first promote the promotion of no less than 10,000 new energy vehicles in the next two years.
In addition to the support at the national level, many local governments with limited purchases and restrictions have more relaxed regulations on new energy vehicles, which has become an important reason for auto companies to recommend new energy vehicles to consumers at this auto show.
Although the country and enterprises have high hopes for new energy vehicles, from the current point of view, the development level of China's new energy vehicles is far from the expected target.
The data shows that as of the end of 2012, a total of 39,000 new energy vehicles have been demonstrated and promoted nationwide. In the first half of 2013, the production and sales volume of new energy vehicles was only 16,381. China's "Energy Conservation and New Energy Vehicle Industry Development Plan (2012 ~ 2020)" proposes: "By 2015, the cumulative production and sales of pure electric vehicles and plug-in hybrid vehicles will strive to reach 500,000 units; by 2020, pure electric The production capacity of automobiles and plug-in hybrid vehicles has reached 2 million, and the cumulative production and sales volume has exceeded 5 million.†Compared with this goal, China's automobile industry still has a long way to go.
Industry analysts believe that although the popularity of new energy vehicles will take time, it is not difficult to see the importance of auto companies to the 2013 Guangzhou Auto Show. New energy vehicles will shift from simple display to large-scale production. The technology that is likely to achieve industrialization is hybrid technology.
New energy vehicles put higher demands on steel
In the future, automotive technology will take safety, energy saving, environmental protection and intelligence as the development direction. As one of the important directions for the future development of automobiles, new energy vehicles will have higher requirements for safety performance with automobiles, and the application of steel for vehicles will be proposed. A bigger challenge.
Kang Yonglin, a professor at the School of Materials Science and Technology at Beijing University of Science and Technology, said that new energy vehicles are more focused on the weight of the body. To achieve lightweight, high-strength, ultra-high-strength steel and aluminum composite lightweight materials can be used, and the design of the vehicle can be optimized from the design. In recent years, the application of thermoformed steel in automobiles has gradually increased. For example, automotive anti-collision parts and side beams of vehicles can be made of thermoformed steel. The advantage of thermoformed steel is that it has simple metallurgical composition, low cost and high strength. . In the future, automotive steel will still have great development potential in terms of comprehensive properties such as strength, stiffness, impact resistance and formability through the comprehensive application of modern metallurgy, materials science and engineering, and computer simulation technology.
He Wei, an expert from the Automotive Industry and Technology Strategy Institute of Tsinghua University, also said that the improvement of material properties is especially important for weight reduction. The use of high-strength steel is an effective measure for lightweighting. The appropriate materials are used in suitable locations and prepared by suitable processes. The optimal structure.
This has been reflected in new energy vehicles. It is reported that in the car body of the SAIC Group Roewe 550 plug-in hybrid car, which has received much attention at the auto show, the application ratio of high-strength and ultra-high-strength steel plates has reached 67%, and the ultra-high-strength UHSD body has been fully comparable. The strength level of the luxury car.
According to industry insiders, in the future, automotive steel still has great advantages in terms of safety, light weight, cost, material life cycle and green manufacturing, and it is still the most important material for automobile manufacturing. In the future, automotive steel will be combined with innovative advanced molding manufacturing technology and combined with lightweight materials such as aluminum alloys to make vehicles lightweight and discharge meet the requirements of higher specifications.
Future automotive steels will also use modern computing design techniques to optimize components and overall structure and achieve growth and competitiveness through the provision of total solutions.
The plastic netting is processed and made of polyethylene and polypropylene. It have the performances of wear-resisting, corrosion-resisting, fine toughness, it can instead of metal wire.
Colour: black, white, blue, green ,yellow, red, etc.
Uses: main used in oil, chemical industry, aquatic breed, back cushion of car, Simmons mattress, air conditioner wire mesh, stop burn wire mesh ,and road bed mesh, etc.
New energy vehicle development will put higher requirements on steel
At the Guangzhou Auto Show that opened recently, new energy vehicles have once again become the focus of the industry. Whether it is a foreign brand, a self-owned brand, or a joint venture brand, almost all new energy models have been launched at this year's auto show. According to industry sources, the Chinese auto market is expected to usher in the climax of the popularization of energy-saving new energy technologies represented by hybrid technology. The development of new energy vehicles puts higher demands on automotive steel.
