The electric arc furnace (EAF) is one of the popular methods of steel production from steel scraps. The plasma arc is used in EAF to generate heat for melting scarp or direct reduced iron (DRI). The liquid metal is drained from the EAF through the tap hole. Nowadays, it is critical to use Automated/robotic tools for opening the tap hole with oxygen lancing. Because many workers have been blinde...

This paper describes how to calculate the different harmonic sequences that should be filtered with a shunt selective active filter, for two control alternatives: load current measurement or line current measurement. These results are then generalized for shunt hybrid selective filters. Passive parameters are chosen considering the resonances with the electric system that appear. Design basis a...

The purpose of this study was to identify and assess dust exposure in Electrical Arc Furnaces for steel manufacturing. The major concern of steel making processes is dust generation and accumulation. The scope of this research paper focuses on different ways to improve current controls and make recommendations. In order to achieve the purpose, various goals were developed to identify the extent...
