生阳极制备过程主要技术参数分析及优化

Analysis and optimization of main technical parameters in green anode preparation process

对国内某炭素厂生阳极生产过程各环节主要技术参数,从预热、混捏、糊料冷却、成型、工艺配方等方面进行分析,并针对沥青使用量、球磨粉纯度、配方控制、混捏成型参数等提出优化措施并予以实施,使生阳极产品质量得到提升,并跟踪实际使用情况,改进后阳极质量的提升,使得阳极在电解槽的换极周期以及毛耗水平指标得到明显改善。

Main technical parameters during the production process of green anodes in a domestic carbon plant are analyzed from perspectives of preheating,kneading,paste cooling,forming and recipe.Optimization measures are proposed and implemented for the pitch content,ball mill powder purity,recipe control,kneading and forming parameters,so as to improve the quality of prebaked anode products.The actual utilization situation is also tracked.After the improvement of the anode quality,the anode change cycle and gross consumption indicators in the aluminum reduction pot are significantly improved.
