自 Hall-Heroult 电解法(简称 H-H 法)问世以来已有近百年的历史。由于冰晶石——氧化铝熔体电解法能耗大,因此一直围绕着节省电能和扩大原料来源的问题,不断地完善H-H 法,并且又相继研究和发展了许多其它的生产方法。本刊编辑部根据国内外科技情报资料对各种炼铝方法进行了广泛调查研究,为进一步摸清今后炼铝研究方向,为确立我国科研战略提供依据。现将几种主要炼铝方法评述如下:
Almost a century has passed since the Hall-Heroult electrolysis (H-H method) came out. As cryolite-alumina melt electrolysis consumes a large amount of energy, it has been focusing on saving electricity and expanding sources of raw materials, continuously refining H-H method, and successively studying and developing many other production methods. Our editorial department based on domestic and international scientific and technological intelligence information on a variety of aluminum smelting methods conducted extensive investigations and studies, in order to further find out the future direction of aluminum smelting, to establish the basis for our scientific research strategy. Now several major aluminum refining methods are as follows:
