目前我国2万吨/年以下产能的铝电解企业有70家左右,其中最小的产能仅千余吨;地方建设电解铝由于受到资金限制,生产规模都比较小,再加上小型自焙槽电解铝厂具有投资省、建设速度快、工艺流程简单等特点,故那时上马的多数电解铝厂普遍采用的都是60KA侧插自焙阳极电解槽。我国侧插自焙阳极电解槽约有150～170万吨的生产规模,占我国原铝总产能的65％左右。目前我国铝工业面临的主要问题是:一方面,随着国民经济的高速发展,国内铝的需求必然持续增长,而占国内铝产能65％左右的
At present, China has an output of about 20,000 aluminum electrolytic plants with a production capacity of less than 20,000 tons per year, of which the minimum production capacity is only about 1,000 tons. Due to the limited funds and the limited production scale, local electrolytic aluminum production, combined with small self- Aluminum plant with investment in the province, the construction speed, simple process characteristics, so most of the electrolytic aluminum plant was launched at that time are 60KA side inserted self-baking anode electrolyzer. China side self-roasted anode electrolyzer about 150 to 1.7 million tons of production scale, accounting for about 65% of China’s total primary aluminum production capacity. At present, China’s aluminum industry is facing the main problems are: On the one hand, with the rapid development of the national economy, the domestic demand for aluminum is bound to continue to grow, while the domestic aluminum production capacity of about 65%
