铝用阳极干料配方粒级优化

为了解决某些企业炭阳极生产所用的干料配方振实密度低、孔隙度较高最终导致炭阳极各种性能指标差等问题,通过确定干料配方水平、因素建立正交试验，将试验结果与现阶段工业应用的干料配方作对比，对干料配方进行优化。结果表明，配方A1、A2、A3振实密度高且符合生产实际，该配方主要适用于因生产实际无法大规模更新设备或者改造料仓的情况，解决了一部分生产问题，该配方可以提高炭阳极振实密度，对炭阳极提升具有明显效果。

Optimization of dry aggregate particle size of anode formula for aluminum

In order to solve the problems of low density and high porosity of dry aggregates used in the production of carbon anodes in some enterprises, which ultimately led to the poor performance indexes of carbon anodes, the orthogonal test was established by determining the level and factors of dry aggregates formulation. As well as, the experimental results were compared with the dry aggregates formulation of the industrial application at the current stage to optimize the dry material formulation. The results showed that the formulations A1, A2, A3 had high tap density and were in line with the actual production situation. This formulation was mainly suitable for the large scale updating of equipment or modification of silos due to the actual production, and solved some production problems. The formulation can increase the mechanical density of the carbon anode and increase the mechanical strength, and had obvious effects on the carbon anode lifting.
