| Abstract Scope |
The Electric Arc Furnace (EAF) is widely used in the steelmaking process. Graphite electrodes has played a significant role in EAF steelmaking process to generate very strong arc with high voltage, which provides a huge amount of energy demanded for scrap melting. Generally, the electrodes is bored into the furnace from the top. Meanwhile, several burners around the furnace was injecting fuel and oxygen to provide chemical energy for the scrap melting. In order to investigate the effect of electrode movement to the in-bath scrap temperature and potentially optimize the scrap melting process, numerical simulation of scrap melting by moving electrode in an EAF was conducted. A three-dimensional computational fluid dynamics (CFD) model was developed with electrode movement and heat transfer from the electrode and oxy-fuel combustion to solid scrap. This model will be further developed to include numerical simulation of solid scrap movement and liquid scrap dripping. |
