日本是世界上消费铝较多的国家。10年前日本的原铝生产量只能满足国内需求的60～70％。1978年以后,日本的电解铝厂相继停产关闭,现在每年需要原铝锭已超过200万吨,其中98％以上靠进口解决。用于炼制铝锭的铝废料的回收利用逐步引起人们的注意,特别是最近几年,再生铝锭的需求逐年增加,1988年再生铝锭产量为953626吨,1989年上半年为500555吨。现在铝需求量的1/3靠再生铝锭来
Japan is the country that consumes more aluminum in the world. 10 years ago Japan’s primary aluminum production can only meet the domestic demand of 60 to 70%. After 1978, the electrolytic aluminum smelters in Japan have been shut down one after another, and now the annual needs of the original aluminum ingot has exceeded 2 million tons, of which over 98% are imported. Recycling of aluminum scrap used for the refining of aluminum ingots has gradually drawn people’s attention. Especially in recent years, the demand for recycled aluminum ingots has increased year by year. The output of regenerated aluminum ingots in 1988 was 953,626 tons, compared with 500555 tons in the first half of 1989. One-third of aluminum demand now comes from recycled aluminum ingots
