After 90 years of development, China's aluminum foil industry has made world-renowned achievements and has become a large global producer and exporter. 2020, China has about 157 aluminum foil enterprises with production of 4050kt, accounting for about 65% of the world; domestic apparent consumption of 2840kt, accounting for 70%; exports of 1210kt, accounting for 30%; production capacity of nearly 6000kt/a, with a capacity Utilization rate of 67.5% (a bit lower, good to reach 85%); 71 foil mills with roll width ≥ 2000mm nationwide, of which 45 were introduced. From 2020 onwards, China's aluminum foil industry sets sail on a new journey, with 11 aluminum foil projects under construction and in operation between July 2019 and March 2021, with a total production capacity of 1013kt/a, which has never been seen in the history of the aluminum foil industry.
In 2020, the total aluminum foil production is 6230kt, but the per capita consumption of aluminum foil varies greatly from country to country, according to the "Global Aluminum Foil Producers Initiative (GLAFRI)": in 2017, the global per capita consumption was 0.7kg; South Korea 1.9kg, North America 1.79kg, China 1.61kg, the It is estimated that by 2028, China's aluminum foil consumption could reach 3500kt, or nearly 2.5kg per capita, which could be at or near the top, and of course grow slowly some more, but thereafter production But after that, the rise of production is mainly determined by the export volume, and Chinese aluminum foil is quite competitive in the international market.
The author divides the development of China's aluminum foil industry into four stages: the period of initial knowledge from 1932 to 1960, the period of initial creation from 1961 to 1980, the period of rapid development from 1981 to 1999, and the period of new sailing from 2000.
1932-1960: The period of first acquaintance of China's aluminum foil industry
At the beginning of the 20th century, China's tobacco industry was booming and the demand for aluminum foil used for cigarette packaging was large, and all the aluminum foil used at that time was imported. In this situation, three aluminum companies from Canada, Switzerland and the United Kingdom used the old equipment eliminated by Swiss Aluminum to build a Chinese national aluminum foil factory in Yangpu District, Shanghai, called Shanghai Steel Fine Factory.
In 1935, the melt casting, plate and strip rolling equipment was put into operation one after another, and the equipment for disc and foil coloring, embossing and laminating was added, and the monthly output was as high as 400 t. By now, Hualu Steel Precision Plant had become a complete aluminum plate, strip and foil The aluminum ingots used were imported from Canada, England, Norway, Switzerland and other countries, and the products were sold in the domestic market. The average monthly output of the plant in 1948 was 290t, of which 150t was foil and 70t each was aluminum sheet (including discs) and strip.
In addition to producing tobacco foil, Hualu Steel Refining Plant also produced paper-laminated aluminum foil (0.009mm thick) for wrapping candies, tea foil (0.014mm thick) for laminating kraft paper, and aluminum foil (0.006mm-0.0075mm thick) for capacitors without laminating paper. After the liberation of Shanghai, the capitalists lost interest in the operation of the enterprise and the output dropped significantly, from 300t~400t to 70t~80t per month, under such circumstances, the Party and the State promptly adopted the policy of "utilization, restriction and transformation" for private industry and commerce, which promoted the recovery of production and market prosperity. Before July 1960, the output of Hualu Steel Refinery was maintained at about 1000t/a, of which only 100t/a of aluminum foil was produced. Shanghai Aluminum Factory", which was subordinate to Shanghai Light Industry Bureau.
The production of the state-run Shanghai Aluminum Factory developed extremely fast, and the production outlook changed dramatically in half a year, with the output of aluminum rolled products increasing exponentially, with an average monthly output increase of 414.4%, an average monthly output increase of 385.4%, and a labor rate increase of 248.2% compared with that before the state-run factory. The production volume of aluminum foil did not expand and remained at 1800t/a.
In 1959, the Liaoning Electronic Aluminum Foil Plant (Dandong Aluminum Foil Plant) was put into operation with a production capacity of 900t/a. This means that in 1960, China's aluminum foil production capacity was 2,700t/a.
1961～1980 The initial period of China's aluminum foil industry
In 1976, the Ministry of Metallurgical Industry approved the construction of a new aluminum foil section at Northeast Light Alloy Company, and in 1980, a four-roller 1200mm foil mill, the first foil mill of its kind in China, with a production capacity of 900t/a, was put into operation from Ashenbach, West Germany. Ltd. built an aluminum foil workshop with a production capacity of 5,000t/a, following the model of Hualu Steel Precision Plant. Due to the lack of experience, none of the 93 sets of equipment in the trial production could be used normally and had to be renovated. In the 20 years from 1961 to 1980, nine aluminum foil plants were built around China based on this workshop, with a total production capacity of about 13.5kt/a.
The Northwest Aluminum Processing Plant was a large-scale aluminum processing plant built in the 1960s, a relocated enterprise, built according to the "Third Line Construction" plan, with leading equipment and some key personnel drawn from Northeast Light Alloy Co.
In October 1977, the Ministry of Metallurgical Industry decided to build North China Aluminum Processing Plant in Zhuo County, Hebei Province, and broke ground in September 1978. As of December 1980, the first phase of the project was put into operation, forming a sheet and strip production capacity of 5000t/a, rolling 550t of sheet and strip with double-roller continuous cast and rolled strip billets as billets, deep-drawn some products and a small amount of foil, which is a milestone in the development of China's aluminum processing industry.
From 1981 to 1999, the period of rapid and great development of China's aluminum foil industry With the rapid development of reform and opening up, China's aluminum foil industry also entered a period of rapid and great development, introducing a large number of technologies and equipment. in 2004, China exported 75kt of aluminum foil and imported 64.4kt, with a net export of 10.6kt, and China has been a net importer of aluminum foil since 1918. in 2006, the China produced 788kt of aluminum foil, surpassing the 780kt of the U.S., and took the lead. In January 1981, North China Aluminum Processing Plant started to build the second phase of the project and decided to introduce one Φ420/1100×1600mm four-roller irreversible cold rolling mill from Kobe Steel Company of Japan, which is the first cold rolling mill reaching the level in China, and also introduced one Φ260/700×1600mm aluminum foil rough and medium rolling mill and one Φ260/700×1600mm aluminum foil medium and fine The plant was put into operation on December 25, 1982. At the beginning of 1984, the third phase of the project was built and put into operation in 1986. was established.
In February 1981, North China Aluminum Processing Plant sent the cast rolled strip coil produced by the self-reliant continuous casting and rolling line to Japan's Koyama Aluminum Rolling Plant for trial rolling of aluminum foil, and the average yield of the rolled 0.007mm×260mm foil reached 75.8%, the quality of which was almost equal to that of Japanese foil, indicating that China's casting and rolling line could produce qualified aluminum foil strips, laying the foundation for China to become a large and powerful aluminum foil country in the future. The foundation for China to become a big and strong aluminum foil country.
Since the 1980s, especially after the Third Plenary Session of the Eleventh Central Committee of the Party, with the opening up of the country to the outside world and the implementation of the economic policy to the inside, the country has sent a number of engineering and technical personnel and cadres at all levels to study abroad and invited foreign experts to exchange technology, so as to understand and see the development of aluminum processing today and find out the gap with foreign technology. Since then, China's aluminum foil industry has entered a phase of high-speed and continuous construction and production, with all completed projects reaching the international level or international standards, and by December 2010, all two-roller foil mills had been eliminated in accordance with the national structural adjustment policy. 2007 saw China among the primary powerhouses of aluminum foil.
Among about 150 aluminum foil enterprises of existing scale, there are about 11 with double-zero foil production capacity ≥ 100kt/a, they are: Zhongji Composite Materials Co., Zhongwang Group (Yingkou plant and Tianjin plant), Hongqiao Aluminum Co., Ltd (Zouping plant and Weihai plant), Shenhuo Aluminum Co., Ltd (Shangqiu plant and Shanghai plant), Zhenjiang Dingsheng Aluminum Co. Ltd., Shengtong Aluminum Co., Ltd., North China Aluminum Co., Ltd., Chinalco Group (Northeast Light, Northwest Aluminum, Henan Aluminum, Southwest Aluminum, Ruimin), Yunnan Aluminum Company (Huxin, Yongxin, Haoxin, etc.).
The billet rolls used for the production of aluminum foil are double-rolled continuous casting and rolling, ingot hot rolling, and Hazlet continuous casting and rolling, and the main one used in China is casting and rolling. 2020, there are about 900 double-rolled casting and rolling lines in China, and the production capacity of casting and rolling rolls is about 9000kt/a. About 70% of the aluminum foil in China is produced with cast rolls and billets, and 28.7% of the foil is produced with hot rolled billets. This is only in the field of aluminum foil production, which shows that the technology and process of producing aluminum foil in China resides at the level of 1.3% of the usage of HAMLET continuous casting and rolling strip billets, though the usage will rise in the future.
China's aluminum foil industry in 2000 A new period of sailing
China's aluminum foil industry has a special significance in its development journey from the first half of 2019 to March 2021: 1013kt/a of production capacity under construction and in operation. by 2030, China's aluminum foil production capacity may rise to a "ceiling" of 7500kt.
