1.概况我国的铝工业发展比较缓慢,不能适应国民经济增长的需要。为此,国务院做出了“优先发展铝”的决策。我国目前铝产量约有50万吨,每年尚需进口30万吨。因此,解决需求矛盾以立足发展国内铝工业有利。江苏工业发达,各行业用铝量很大,约为全国的10％,且以每年8.9％的速度递增。但本省铝的自给率仅12％。若实现以铝代钢,小轿车为14∶1,地铁构件为5.6∶1,铝门窗高达24∶1,则缺口将更大。
1. Overview China’s aluminum industry is developing relatively slowly and can not meet the needs of national economic growth. To this end, the State Council made a “priority development of aluminum” policy. At present, there are about 500,000 tons of aluminum in our country and 300,000 tons still need to be imported each year. Therefore, to solve the contradiction between the needs of the domestic aluminum industry based on the development of favorable. Jiangsu developed industry, with a large amount of aluminum industry, about 10% of the country, and the annual rate of 8.9% increase. However, the province’s self-sufficiency rate of aluminum is only 12%. If you achieve the aluminum-steel, the car is 14: 1, the subway component is 5.6: 1, aluminum doors and windows up to 24: 1, the gap will be greater.
