What is the progress of Zhengzhou's advanced manufacturing ecosystem construction? What are the key enterprises and key technologies?

What kind of "fantasy drifting" will an aluminum can experience? Maybe the raw material of the can in your hand comes from an aluminum factory in Zhengzhou, and after being used up, it returns to another aluminum factory in Zhengzhou to be refurbished into a more advanced aluminum plate, which floats all over the world and becomes a car, Accessories for high-end products such as electronic products.

A small can, from production to use, to recycling, to reuse, draws a circle.

For every 10 cans of soda cans, 1 can body material is produced in Zhengzhou

"Our can body materials account for 10% of the global market share. Among the cans that people usually drink, one can body material is produced by Zhongfu for every 10 cans; in the domestic market, there is one can lid for every three pop cans. The can lid material comes from Zhongfu." Cao Yongguo, deputy general manager of Zhongfu High-precision Aluminum Material Company located in Gongyi City, Zhengzhou, told reporters.

Pop cans seem common and simple, but they contain many internationally leading technologies, and their production mainly comes from the aluminum industry. Cao Yongguo said: "We have always been accelerating the pace of self-reliance and self-improvement in science and technology to solve the problem of foreign 'stuck necks'. The aluminum industry is one of the six leading industries in Zhengzhou City. Zhongfu has continuously strengthened its core advantages in independent innovation and built a core business of aluminum deep processing. ability."

In 2022, the sales volume of can bodies, can lids and pull ring materials produced by Zhongfu Industry will account for more than 80% of the company's products, and the export sales will reach about 305,600 tons. The company has become a mainstream supplier of can body materials, can lid materials, and pull ring materials for cans. Not only that, its wholly-owned subsidiary Zhongfu High-precision Aluminum Material Co., Ltd., as a leading enterprise in Zhengzhou aluminum and aluminum deep processing, can also mass-produce more advanced, industry-leading 0.235 mm thick ultra-thin tank materials, 0.208 Millimeter thick ultra-thin can lid stock.

In addition to cans, the company also continuously optimizes the structure of aluminum deep-processing products and domestic and foreign sales markets, and is one of the batch material suppliers of the world's largest auto panel manufacturers.

In fact, Zhongfu High-precision Aluminum Co., Ltd. is the epitome of the transformation and upgrading of Zhengzhou's aluminum industry.

Scientific research of leading enterprises gathers strength

Not only Zhongfu Industry, but also in Gongyi, Yulian, Mingtai, Wanda, Xintai and other leading aluminum deep processing enterprises gather here. Gongyi, which takes high-precision aluminum and new materials as its leading industry, has realized the transformation from traditional Products shifted to the field of aluminum deep processing. The reason why Gongyi has become a leading enterprise cluster for aluminum deep processing is closely related to the company's strong investment in scientific research, innovation, equipment, and talents. As Yirui New Material's new hot rolling production line in 2023 is about to be put into use, the hot rolling production line in Gongyi Advanced Manufacturing Development Zone has accounted for 1/3 of the country's active production lines, plus six-roll cold rolling, cold rolling The domestic leading equipment such as the second continuous rolling mill has been put into use one after another, and the overall equipment level of the development zone is in a leading position in the country.

The industrial control systems of Beijing University of Technology, Hefei University of Technology and other colleges and universities have been applied in the Advanced Manufacturing Development Zone of Gongyi City, Wanda’s hot air gas burner has been renovated, Zhongfu’s new cold rolling line has been put into production, and Hengtong’s cold rolling technology has been upgraded. Upgrading, the overall production capacity of the industry has increased by nearly 30%.

The main industrial product of Gongyi City Advanced Manufacturing Development Zone is aluminum rolling processing, which is in the middle reaches of the industrial chain. Technology research and development is the key to breaking through the bottleneck constraints of upstream and downstream. Enterprises in this area combine their own characteristics to make efforts in technology research and development. At present, there are two national-level enterprise technology centers, Zhongfu and Mingtai. Zhongfu Industry has participated in the implementation of 3 national projects and is one of the national standard-setting units for cans; Ming Three technologies of Tai Aluminum Industry won the national ministries and commissions science and technology awards, and participated in the formulation of industrial standards for recycled aluminum; a group of aluminum processing enterprises such as Ai Ruihai and Xintai participated in the formulation of industry standards in the field of subdivided aluminum alloys.

A large number of applications of new technologies have brought about a sharp increase in market share. Zhongfu’s can body materials have a global market share of 10%, and the domestic market share of aluminum alloy strips for easy-open lids has reached more than 30%. High-performance recycled flat-rolled aluminum The global market share of alloy materials is 10%; Wanda Aluminum is the only one among the 5 series aluminum alloy products. The self-developed easy-open lid material accounts for 30% of the industry share, and the market share of super-hard, super-strong and high-toughness aluminum alloy sheets is nearly 80%. .

According to statistics, there are 15 smart workshops and smart factories above the provincial level in the Advanced Manufacturing Development Zone of Gongyi City. The three-dimensional intelligent warehouse innovatively built by Mingtai Aluminum has realized intelligent unattended logistics, fully automatic, and a digital management system covering all enterprises. It can directly access data and business flash batches across the country. The MES-based production, supply, marketing and storage system Extensive application brings large-scale coverage of enterprise cloud.

Recycled aluminum leads the industry's new track

After the aluminum cans are used up, they may return to a factory in Zhengzhou. In the production workshop of Henan Yirui New Material Technology Co., Ltd., discarded aluminum doors, windows, and cans are sorted and enter the production line. After smelting and purification, they are "transformed" into higher-grade aluminum panels, and finally become automobile interiors. , Electronic product accessories and other high-end products.

"Through multiple processes such as casting, hot rolling, and cold rolling, the use of high-efficiency, energy-saving, clean, and large-scale technologies can realize the harmless, high-value, and green recycling of waste aluminum resources, leading the industry into an efficient resource cycle. The 'zero waste' era of utilization." said Li Zhiyang, director of the government affairs department of Henan Yirui New Material Technology Co., Ltd.

Yirui New Material Co., Ltd. is advancing the annual production of 700,000 tons of green new aluminum alloy material projects. Through the introduction of internationally advanced recycled aluminum alloy slab production lines, intelligent 1+4 hot rolling production lines, and CVC6-roll cold rolling mills, etc., The high-efficiency output of green new aluminum alloy materials has been realized.

The secondary aluminum industry is an emerging industry, and it is a green and environmental protection industry. Data show that the energy consumption per ton of recycled aluminum production is only equivalent to 3% to 5% of electrolytic aluminum, which can save 3.4 tons of standard coal, save 14 cubic meters of water, and reduce solid waste discharge by 20 tons. Especially under the background of my country's "carbon peak and carbon neutrality", the carbon emission per ton of recycled aluminum is only 0.5 tons, which is about 5.8% of electrolytic aluminum.

"Experience over the years has proved that the aluminum processing industry, which uses recycled aluminum as the main raw material, has more cost advantages, more market competitiveness, and better economic benefits." Li Zhiyang said.

Only this green background of the industry

If the booming aluminum industry in Zhengzhou has a background, it must be "green".

This touch of green is the iterative upgrading and high-quality development of the industry.

In Henan Yirui New Material Technology Co., Ltd., next to the production workshop is a behemoth - a large-scale waste heat recovery system, which recycles and reuses the high-temperature waste gas generated in the smelting process, so that the waste heat and flue gas can be "eaten dry and squeezed clean", "yearly Produce 70,000 tons of steam, save 6,200 tons of standard coal annually, and reduce carbon emissions by more than 18,000 tons."

This touch of green is the gradual improvement and sustainable development of the ecology of the aluminum processing industry chain.

"As big as the equipment parts of the navigation and aviation, as small as a mobile phone card slot, almost all the batches of aluminum can be found in the park." Luo Xiaoxiong, chief engineer of Henan Wanda Aluminum Co., Ltd., said that Wanda Aluminum is less than 100 meters away. The downstream enterprise of Henan Ai Ruihai New Material Co., Ltd., some products of Wanda Aluminum will be further processed here to realize the upgrading of the extended industrial chain of the aluminum processing industry.

This touch of green is the "green water and green mountains" of the business environment and the "confidence index" to enhance the development of enterprises.

"The Yirui new material project is a wholly-owned subsidiary of Mingtai Aluminum, a listed company in our development zone. When we understand the company's needs for new projects, we will connect with the company as soon as possible to understand the company's needs, and report each case on a special topic. The municipal government will give enterprises the greatest preferential policies and fully serve the enterprises.” said Yan Longtao, Deputy Secretary of the Party Working Committee and Deputy Director of the Management Committee of Gongyi City Advanced Manufacturing Development Zone.

The integration of ecology and industry, and the win-win situation of "increasing income" and "increasing greenness" are the secrets to the vigorous development of Zhengzhou's aluminum industry.
