氧化铝工业发展与电解铝工业发展密切相关。由于铝市场的萧条,对铝需要量的减少,给氧化铝工业的发展带来了不利的因素。特别是铝产量较大的美国,由于高利率政策,建筑业和汽车制造业方面需要量降低,其电解铝设备开工率己下降到66％,比1975年下降了9％。1981年铝锭的生产量与1980年相比降低了2.46％。氧化铝的产量,1981年与1980年相比下降了5.2％。 1980年氧化铝产量最高的国家是澳大利亚,其次
Alumina industry is closely related to the development of electrolytic aluminum industry. Due to the slump in the aluminum market, the reduction of aluminum demand has brought unfavorable factors to the development of the alumina industry. In particular, the United States, which has a large aluminum output, saw its utilization of electrolytic aluminum equipment drop to 66%, down 9% from 1975, due to the high interest rate policy, the lower demand in the construction and automobile manufacturing sectors. In 1981, the production of aluminum ingot was 2.46% lower than in 1980. The production of alumina dropped by 5.2% in 1981 compared to 1980. The country with the highest alumina output in 1980 was Australia, followed by
