摘　　要：对炭阳极弹性模量进行研究,可反馈阳极内部结构状态,有助于评价阳极的抗热震行为。本文选用先进的进口检测分析设备,采用静力学法和声频共振法,通过测定铝用炭阳极的静态和动态弹性模量,初步研究阳极弹性模量与其理化性能指标之间的关系。研究表明,阳极弹性模量与阳极物理性能和裂纹状态存在明显相关性。控制炭阳极的弹性模量,可以减轻阳极热脆行为及控制阳极的内部缺陷程度,有助于提高炭阳极在电解槽使用性能,改善电解铝操作环境。To study of carbon anode modulus of elasticity, we can realize the internal structure of carbon anode and help to value the behavior of thermal shock resistance. This paper adopts advanced import detection and analysis equipment. We use static method and audio resonance method to test Young＇ s Modulus. From the test we research the relations between the modulus of elasticity and its＇ physical performance, then it can value the significance in quality control of carbon anode. Through control the modulus of elasticity, it can reduce the heat brittle behavior and control the anode degree of internal defects.It is helpful to improve the using performance of the carbon anode and improve the operating environment of the electrolytic aluminum.
