Understand how electrode paste and graphite electrodes differ, where each product is used, and which furnace terms matter before comparing grades, dimensions, or specifications.
Why are these electrode systems not interchangeable? Graphite electrodes and self-baking (Söderberg) electrodes are parts of different equipment systems. A graphite electrode is manufactured, baked
Summary of Findings Current does not enter a Söderberg electrode through its material properties alone. It crosses a mechanical interface first — the contact shoes
How should paste consumption be calculated? Calculate electrode paste consumption from a defined-period material balance: opening usable inventory plus received paste, minus closing usable inventory
Summary of Findings Electrode paste block geometry affects packing voids, melt-down time, gas escape paths, and fines generated during handling. A suitable block or briquette
The baking zone sits above the contact shoes. Learn how current, slipping rate, paste properties, and cooling move it and affect electrode behaviour.
Summary of Findings Volatile matter is not an impurity to be minimised. It is the part of the binder phase that evolves as gas during
