Silicomanganese (SiMn) is an alloy used in steelmaking to provide both Si and Mn additions at low carbon contents. In South Africa, SiMn is produced in three-phase alternating current (AC) submerged arc furnaces (SAFs) by carbothermic reduction of manganese ores in the form of lump, sinter, and briquettes (Steenkamp and Basson, 2013). In a SAF the electrode tips are submerged in a porous charge...

Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

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...

This study deals with a new approach to tackle the challenges encountered in filters-based reactive power calculation techniques utilized control system of static VAr compensators. In this approach, step and time-varying responses are improved by combination differential filter-based methods. Then, optimum values main parameters low-pass band-stop filters determined considering three criteria: ...
