摘　　要：分析阳极裂纹的形态外貌和引起阳极裂纹的应力原因归类,指出除固体材料应力变化、内部缺陷外,生块与焙烧裂纹多与半塑性态下物相转变引起的应力有关。研究并指出了一系列工艺因素对阳极裂纹的影响。The morphology of the cracks of carbon anode blocks is analyzed, of which the corresponding factors are classified accordingly. It is pointed out that the cracks of green and baked carbon anode blocks related with the stress are due to the phase transformation in semi-plastic state as well as due to the stress change of solid material and internal defects. The effects of preparation parameters on the cracks of carbon anode blocks are also addressed.
