当前,我国的铝加工工业已具有相当的规模。全国的铝消费量一年已近百万吨,除掉铸件和电线、电缆外,铝加工材的产量一年也有五十万多吨。当然,生产能力还要大得多,但是,数量不少,水平不高。所谓水平不高,技术装备落后故然是重要的方面,不仅如此,还有品种不全、质量不高、消耗大、劳动生产率低、经济效益不好等等。总而言之,科学研 At present, China’s aluminum processing industry has a considerable scale. Aluminum consumption in the country is nearly one million tons a year. Besides the production of castings, wires and cables, the output of aluminum processing materials is also over 500,000 tons a year. Of course, the production capacity is still much larger, however, a large number, the level is not high. The so-called low level, technical equipment behind is an important aspect, not only that, but also incomplete, low quality, high consumption, low labor productivity, poor economic efficiency and so on. In short, scientific research
