自2000年以来,尽管河南省的氧化铝产量以年均23％的速度增长,但是河南省电解铝的年均增幅却超过了50％,而且这一差距还在逐步扩大。去年,河南省的氧化铝产量达到211万吨,进口量达到100万吨,今年的进口量可能要超过150万吨。可是,去年河南省国产氧化铝供应量仅占电解铝需求量的48％,今年这一数据将下降到40％。据预测,今后两年这一数字还有可能进一步下降。
Since 2000, although the output of alumina in Henan Province has increased at an average annual rate of 23%, the average annual growth of electrolytic aluminum in Henan Province has exceeded 50%, and the gap is still widening. Last year, Henan Province’s alumina output reached 2.11 million tons and its import volume reached 1 million tons. This year, the volume of imports may exceed 1.5 million tons. However, last year, Henan Province, the domestic supply of alumina accounted for only 48% of the demand for electrolytic aluminum, this year this figure will drop to 40%. It is predicted that this figure is still likely to decline further in the next two years.
