Abstract Scope |
Søderberg electrodes are used commonly in submerged arc furnaces for production of ferroalloys and non-ferrous metals. These electrodes, used to supply AC current into the furnace, consists of paste (a mixture of petrol coke and coal tar pitch) that eventually gets baked - a temperature driven process.
With increase in the electrode size and current supplied, safe operation of the electrode requires models that can predict the conditions experienced during operation. Such models, often referred to as 'electrode models', have predominately been developed by Elkem in literature.
In this work, a novel axisymmetric transient Søderberg electrode model is presented. The model is used to simulate an electrode undergoing various slips, variations in electrode current, casing/briquette addition, and other operational scenarios, such as shut down operation. The model is observed to run much faster than real time, thus enabling its potential use in hybrid digital twin type of applications in industries. |
