<p>An industrial process for the manufacture of carbon electrodes (artefacts) comprises the steps of (a) mixing a high melting pitch with a Softening Point Mettler (SPM) above 150°C with carbonaceous solids at a temperature of 0°C to 120°C above the SPM of the pitch, pressing or compacting by vibration or extrusion without intentional cooling at a temperature close to the mixing temperature, (b) transferring the artefacts to a carbonization furnace without intentional cooling, (c) carbonizing the artefacts, said process does not need to cool the pitch/coke paste after mixing and/or the green electrode after forming, thus, the heat trapped in the green electrode can be conserved and reduces the total energy consumption and residence time in a subsequent carbonisation step.</p> |
