Using electrode paste is an effective means of augmenting energy in metal production processes, and thus, electrode paste finds application in various industrial procedures such as the production of ferrosilicon, ferromanganese, and ferrochrome.
The electrode paste is mixtured of anthracite, coke or graphite scrap and a binder (coal-tar pitch), and is added into a steel casing on top of the electrode. As the electrode is consumed the electrode and the casing with electrode paste is moved down towards the furnace. The movement of the electrode is called slipping, and the resistive heating from the electrode current and heat from the furnace – heat the new paste. The electrode paste softens as it heats and will fill the whole casing between 50-100°C. The paste is finish baking to a solid carbonaceous body at about 450-500° C. The furnace process and the process temperature will be different for each pro-cess and the temperature gradient in the electrode is believed to change accordingly.
