摘要:
为提高石墨电极的安全性能，采用浸渍法讨论不同活性组分负载的石墨样品在750 ℃环境下的抗氧化性能及影响机制。通过一系列单一活性组分筛选实验和复合活性组分筛选实验讨论活性组分对单位面积质量损失的影响，验证组分优选的可靠性；通过浓度变量实验，得到复合组分浸渍液的优化配比。根据石墨的微观结构和元素组分变化，提出活性组分抗氧化作用机理。结果表明：活性组分与石墨在高温作用下形成的络合物层能够有效延长石墨电极的使用寿命，提高生产安全水平。
Abstract:
In order to improve the safety performance of graphite electrodes,the dipping method was used to discuss the anti-oxidation performance and influence mechanism of graphite samples with different active components load in 750 ℃ environment.The influence of the active components on the mass loss per unit area was discussed through a series of single active component and composite active components screening experiments,and the reliability of component optimization was verified.Through the concentration variable experiments,the optimal ratio of the composite component dipping solution was obtained.According to the microstructure and element composition variation of graphite,the anti-oxidation mechanism of the active component was proposed.The results showed that the complex layer formed by the active components and graphite under the effect of high temperature could prolong the service life of the graphite electrode,and improve the level of production safety.
