大型铝电解槽的特点是对引起碳素槽底整体性破坏的应力具有明显的敏感性。碳块内衬的薄弱环节是碳缝。焙烧槽底时,由于底糊的收缩和底部碳块的膨胀,碳缝中出现了内应力,导致形成微观裂纹。裂纹的大小决定于槽
The characteristic of large aluminum cells is their obvious sensitivity to the stresses that cause the integrity destruction of the bottom of the carbon tank. The weakest link in the carbon block lining is the carbon seam. Roasting the bottom of the tank, due to the contraction of the bottom paste and the expansion of the bottom carbon block, there is an internal stress in the carbon seam resulting in the formation of micro-cracks. The size of the crack is determined by the groove
