Definitions
- the life of the cathode blocks is limited by a number of influences.
- At least a portion of carbon in the cathode block is converted to graphite.
- a cathode block produced by a method according to the invention has a bulk density of a carbon content of more than 1.68 g / cm 3 , more preferably of more than 1.71 g / cm 3 , in particular of up to 1.75 g / cm 3 .
- the second type of coke may have a greater shrinkage and / or expansion, as described above for the first coke variety.
- the second layer may have a height which is 10 to 50%, in particular 15 to 45%, of the total height of the cathode block.
- a small height of the second layer such as about 20%, may be advantageous because a small amount of more expensive hard ceramic material is needed.
- a high height of the second layer such as 40%, may be advantageous since a layer that possesses hard ceramic material has high wear resistance. The greater the height of this highly wear-resistant material relative to the overall height of the cathode block, the higher the wear resistance of the entire cathode block.
- FIG. 2 shows a schematic representation of the shaping of a cathode block according to the invention as a multi-layer block.
- two types of coke are used, the first of which already have a shrinkage during the heating phase in the carbonization and / or graphitization step.
- the second of the two types of coke has a significantly greater shrinkage (in terms of shrinkage after carbonation, graphitization and cooling relative to the starting volume) than the other type of coke.
