中国铝箔工业90年回眸(1)

Review of China aluminum foil industry in the past 90 years (1)

中国首个铝箔厂——上海华铝钢精厂1930年开建,1932年投产,已90年了。笔者对铝箔工业90年的发展历程作了简要回顾,将发展历程分为四个阶段:1930年~1958年初创阶段,1959年~1979年缓慢发展时期,1980年~2006年大发展时期(成为世界铝箔第一大国),2007年~2025年是中国成为世界铝箔初级强国时期。2020年中国约有200家铝箔企业,总生产能力约5700 kt/a,产量4100 kt,产能利用率72%。从2022年起中国几乎不需要进口铝箔了。中国铝箔产业的最大特点是以铸轧-冷乳带为主要坯料,可用这种带坯批量轧制0.004 mm厚的超薄箔。本文分为两篇发表。第一篇简要介绍中国铝箱工业发展的历程,主要的铝箔生产企业的情况,引进铝箔轧机情况。

It has been 90 years since the first aluminum foil plant in China,Shanghai Hualv Aluminum Plant,was built in 1930 and put into production in 1932.The development of aluminum foil industry in the past 90 years is reviewed briefly.The development process can be divided into four stages;the initial stage is from 1930 to 1958;the slow development period is from 1959 to 1979 and the rapid development period is from 1980 to 2006,with China being the largest aluminum foil producer in the world.From 2007 to 2025,China has become the primary power of aluminum foil in the world.In 2020,there were about 200 aluminum foil enterprises in China,with a total production capacity of about 5700 kt/a,the output of 4100 kt and the capacity utilization rate of 72%.From 2022 onwards,China will hardly need to import aluminum foil.The biggest feature of China's aluminum foil industry is that the cast-rolled-cold-rolled strip is employed as the main stock to roll ultra-thin 0.004 mm-thick foil in batches.This paper is divided into two publications.The first part briefly introduces the development process of China's aluminum foil industry,the main aluminum foil production enterprises and the situation of introduced aluminum foil rolling mills.
