| Abstract: |
| Cold ramming paste for aluminium electrolysis cells was synthesized with electrical calcinations anthracites, BRS, pitch coke as aggregate and modified pitch, coal tar oil as paste. The effects of particle proportion on performance of cold ramming paste for aluminium electrolysis cells were investigated by means of Dinger-Funk equation and density method. The results show that when particle size distribution coefficient n is 0.45, the performances of cathode paste materials present optimal value, i.e., volume density is 1.583 g/cm3, porosity is 19.2%, resistivity is 63 μΩ?m, and compressive strength is 36.5 MPa. |
