摘　　要：石墨除气转子在冶炼铝的工艺中起到重要作用。本文介绍了一种先采用浸渍复合磷酸盐作基层,然后加以涂层保护的处理工艺,提高其在高温下抗氧化能力。采用涂层保护法能防止铝熔体净化用石墨转子的氧化,有效地延长其使用寿命。通过试验,成功地得出了涂料组成的最佳配方以及涂刷烘干的工艺措施,为这一方法在实际生产中的应用提供了试验数据。The graphite rotator plays an important role in the refined Al technology. A new technology of enhancing the rotator service life was developed based on the complex phosphate impregnation as substrate and coating protection to improve the antioxidation of the graphite rotaor. The coating protection could prevent the graphite rotator for molten Al purification from the oxidation and prolong its service life effectively. The optimum coating constituent and coating drying technology have been determined successfully, which has provided the theoretical and experimental basis for the practical application.
