在振动成型生产阴极炭块过程中 ,直接把TiB2复合材料和炭块基体振动压制成为一体化复合阴极 ,经过焙烧 ,按常规方法在 75kA预焙电解槽上进行砌筑和工业试验 ,两年来试验槽生产稳定 ,炉底干净 ,炉膛规整 ,易于操作维护 ,TiB2 复合层不脱落 ,不起层 ,效果良好。试验槽电流效率提高0 .9% ,直流电耗吨铝降低 1 88kWh,炉底压降也有所降低 ,原铝质量毫无影响。
In the vibration molding of the production of cathode carbon block, the TiB2 composite material and the carbon block matrix directly into a unified composite vibration cathode, after baking, according to the conventional method of 75kA prebaked electrolytic cell masonry and industrial tests, two years of testing Slot production is stable, bottom clean, furnace regular, easy to operate and maintain, TiB2 composite layer does not fall off, can not afford to layer, the effect is good. The test cell current efficiency increased by 0.9%, the DC power consumption of aluminum decreased by 1 88kWh, and the pressure drop at the bottom of the furnace also decreased. The quality of primary aluminum had no effect.
