Industry sources pointed out that the control of automobile exhaust emissions, "stopping order" can only emergency can not cure the problem, reduce the weight of vehicles to reduce fuel consumption, and promote the use of clean energy vehicles (such as electric vehicles), can not affect the people's daily lives Next, long-term energy saving and emission reduction.
Whether it is the lightening of motor vehicles or the promotion of electric vehicles, a large amount of “light metal†aluminum is needed, which also brings about a new round of development opportunities for aluminum enterprises. A group of aluminum companies represented by China Zhongwang is seizing the dual opportunities of environmental protection and the market to achieve a win-win situation between corporate social responsibility and economic interests.
Lightweight and clean energy can cure the problem of traffic pollution
In 2013, lingering haze shrouded in Beijing, environmental pollution, air governance has become the focus of public attention. On the 16th of this month, the Standing Committee of the Beijing Municipal Committee passed the “Beijing Air Heavy Pollution Emergency Response Planâ€, which means that the “Six Stops†measures, such as the “Red Alert Day†of the “Red Alert Day†and the “Six Stops†of suspension of classes, will be formally introduced. .
The control of air pollution and the reduction of exhaust emissions from motor vehicles are an indispensable link. At present, the number of motor vehicles in Beijing is as high as 5.35 million. It consumes about 7 million tons of fuel every year. The annual discharge of pollutants reaches about 900,000 tons, which not only causes serious congestion, but also is the largest source of pollution caused by smog. According to the data from the Beijing Municipal Environmental Protection Agency, the contribution rate of motor vehicles, coal, and dust to PM2.5 was 22.2%, 16.7%, and 15.8%, respectively. In this “black listâ€, the emissions of motor vehicles ranked first.
However, the use of single and double number restrictions to limit vehicle ownership, etc. to control emissions, not only affects people's travel, but also contradicts vehicle consumption. The automobile industry is related to the national economy and the people's livelihood. It is very easy to impose restrictions and administrative interference in consumption, which will easily affect the automobile manufacturing industry.
Therefore, people in the industry pointed out that the "emergency plan" is a short-term emergency measure for "reducing the deterioration of heavy pollution" under extreme weather conditions, but the long-term solution to the problem is not to respond to emergencies but to reduce emissions. One way to reduce emissions is to reduce the weight of the vehicle body to reduce emissions. Second, clean energy is used instead of traditional gasoline and diesel. Only in this way can domestic auto development and atmospheric governance be able to achieve a win-win situation.
Whether it is the use of clean energy or the light weight of motor vehicles, it cannot leave the globally recognized "green metal" - aluminum.
“Aluminum substitute steel†for motor vehicles Aluminium welcomes development opportunities
Aluminum is called "green metal" because of its friendly nature to the environment, and it is also an important metal to promote body weight reduction. "If the weight of vehicles is reduced by 10%, fuel can be reduced by 8%; (vehicles) can reduce carbon dioxide emissions by 20 kg per kilogram of aluminum." Lu Zhongqing, executive director and vice president of China Zhongwang, said, "The government, People’s increasing attention to environmental protection will greatly benefit the development of the aluminum industry.â€
The density of aluminum is about 1/3 of that of steel. If aluminum is used instead of steel to make cars, it can reduce the weight of the vehicle by 30% to 40%. The weight of the manufactured engine can be reduced by 30%. The aluminum radiator is 20% lighter than the same copper product. 40%, aluminum wheels can be reduced by about 30%. The light weight of the car body can greatly improve the speed and control of the car, allowing the same energy to support a longer distance, which is conducive to energy-saving emission reduction and cost reduction.
In addition to light, aluminum can bring higher safety performance. Because the strength of aluminum alloy is better than that of stainless steel, the impact strength of aluminum body is greater than that of steel. Therefore, the safety of occupants in the vehicle can be guaranteed.
Aluminum alloys also have a high degree of anti-oxidation and anti-rust properties. The aluminum body not only effectively protects the appearance of the car, but also makes it difficult to oxidize or corrode internal components, which greatly enhances the durability of the car.
Because aluminum has the above-mentioned various excellent characteristics, aluminum alloys have been widely used today in various parts of automobiles, such as dashboards and engine mounts, aluminum alloy wheels, suspension system parts, bumper crash beams, cylinders, doors, and heat exchangers. Of course, it also includes more and more mid-to-high-end passenger cars with all-aluminum bodies.
However, compared with the amount of aluminum used in automobiles abroad, Chinese cars have a lower aluminum content and are mainly used on four rims, engines, and other automotive parts. “But from another point of view, it also shows that at home, aluminum is There is still a huge space for development in automotive applications.†Analysts said that national policies, in particular, strongly support environmental protection and a low-carbon economy, which will in essence promote the development of lightweight vehicles. "Although there is no domestic scale in the short term, the future "four doors and two covers" will bring about the explosive development of the board market in this area."
The perfect combination of electric cars = clean energy green metal
The energy-saving and emission-reduction of transportation vehicles is another new energy vehicle.
Regardless of the current number of questions about new energy vehicles, there is one thing that is in the consensus of the industry. Under the current conditions of technology and energy supply, traditional energy vehicles will eventually be replaced. As for whether the replacement is electric vehicles or other energy vehicles, it is still not possible. It is known that electric vehicles are currently one of the best choices.
Due to the special nature of the electric vehicle power system, there is a higher level of requirements for the “light†of the vehicle body, which brings about a broader development prospect for the aluminum alloy.
Take Tesla, the globally-popular electric car, as an example, it adopts an all-aluminum body. Because of the use of thousands of lithium batteries as a source of power for electric vehicles, these batteries bring about half a ton of weight. The 97% of the body of Tesla is aluminum, which greatly offsets the heavy load of the battery and reduces the weight of the vehicle. The excellent power management system and aluminum body "balance" "partners" are just right, to achieve the swiftness and longevity of this electric vehicle.
According to reports, Tesla ModelS sold 1,000 vehicles in September in Europe. In October of this year, a young Zhejiang buyer took possession of the first Tesla in the mainland, and Tesla was also gearing up for the Chinese market.
Analysts believe that Tesla has a clear and beautiful vision. Once the market proves the success of its operating model, a large number of imitators will soon emerge, which will generate a lot of new energy vehicle production capacity; At the same time, domestic automakers such as BYD, Geely and Chery are also increasing their investment in electric vehicles with unremitting enthusiasm. Once these production capacities are formed, there will be a considerable life cycle, which will drive the demand for new energy vehicles, especially components for electric vehicles. This means that the upstream industry of new energy vehicles will have a vast market in the future. As the main constituent material of the new energy automobile body, the aluminum industry will benefit greatly from this market opportunity.
The brave person goes first to practice the lightweight strategy of Zhongwang in China
In order to achieve lighter weight in transportation through aluminum-based steel and aluminum-based copper, some forward-thinking companies have taken the lead and began investing heavily in this area. Zhongwang is the representative of the company.
As Asia and China's largest and leading global manufacturer of aluminum extrusion materials, China Zhongwang has formed a strong market position in the field of industrial aluminum extrusion materials. In the next step, Zhongwang hopes to enter the aluminum extrusion press market and become a leader in this field. In 2012, the 3 million-ton aluminum rolled steel production base in Zhongwang in China broke ground and not only spent US$3.8 billion to purchase modern hot-rolled and cold-rolled equipment, equipped with high-tech finishing lines, but also recruited experts from overseas to lead The research, development and production of automobile aluminum plates indicate that Sword refers to the vast market of automotive aluminum.
Zhongwang also has "excellent genes" in this respect. Extruded aluminum extrusions for automobiles are very high in quality requirements, require qualified ingredients, compact and uniform organization, have excellent static and dynamic mildness, and have good ductility and toughness after heat treatment. Therefore, this also imposes higher requirements on the strength of enterprises entering this field. It is necessary to control the temperature and speed in the processes from grinding tool design, alloy composition, solution purification, extrusion and quenching. The process parameters must be strictly controlled. China Zhongwang integrates the “four-in-one†of gold casting, mold design, advanced equipment and product development. It is the only company in China that completely solves all production processes of industrial aluminum profiles, and cooperates with many domestic and foreign auto manufacturers to provide them with Vehicle aluminum profiles. After years of accumulation, the company is also strong in deep processing. The Industrial Aluminum Deep Processing Center completed in 2011 has been put into operation at the end of 2012 and has successfully developed aluminum alloy high-speed railcars, fire engines and semi-trailers.
After the successful transformation from the original architectural aluminum profiles to industrial aluminum profiles, China Zhongwang hopes to win the future of an “aluminum Chinaâ€. Lu Changqing predicted that "China's large-scale application of profiles for aluminum processing products will form scale in the next two or three years with the global emphasis on lightweight development and low-carbon environmental protection, and this pace will increase. â€
