电控电加热技术在镁电解石墨阳极抗氧化处理中的应用

摘要

针对镁电解生产工艺中石墨材料氧化问题,分析研究了阳极石墨常规抗氧化处理方法(高温抗氧化涂镀法、浸渍复合磷酸盐法及一浸二热磷酸浸渍法)及其存在的缺陷,提出了电控电加热技术在镁电解槽阳极抗氧化处理工艺中的应用方案.经实际应用表明,该方案对保证镁电解连续性生产、提高稳定生产和产品指标具有现实意义.%Based on the graphite anode exposition of application in magnesium electrolysis production process,analyze the defect in conventional graphite anode oxidation processing method (high temperature anti-oxidation coating process, compound phosphate impregnation method and a dip hot phosphoric acid impregnated method)and the existence of the pro-posed electric heating technology application in the technics scheme in magnesium electrolytic cell anode oxidation treatment, and obtain the successful implementation to ensure the magnesium electrolysis continuous production.The results show that the application improves the production stability and product index has practical significance.
