加拿大鋁业公司研究直接炼鋁方法,已有十年以上的历史,平均每年用于研究的費用約为500万美元。該公司阿尔維德鋁厂的直接炼鋁設备于1964年已全部制成。在1965年前几个月,电解还原装置、AlCl生成装置、AlCl分解装置,已分阶段的投入了試驗生产。預計在1965年內,全部設备将在試生产基础上投入正 Alcan has been studying the direct aluminum production method for more than a decade and has spent an average of about $ 5 million per year on research. The company’s Alveide aluminum plant direct aluminum equipment in 1964 has been made. In the first few months of 1965, Electrolytic reduction units, AlCl generation units and AlCl decomposition units were put into trial production in phases. It is estimated that in 1965, all the equipment will be put into operation on the basis of trial production
