Steelmaking based on direct reduced iron (DRI, and its compacted derivative hot briquetted iron, HBI) is an anticipated important global alternative to current steel production FeOx reduction in blast furnaces due lower specific CO2 emission. The majority of DRI melted refined the electric arc furnace with different process conditions compared melting scrap raw material composition being rather...

In this study, Aluminium nanoparticles were synthesized by arc discharge method applying direct current between aluminium electrodes in liquid medium without the need to vacuum equipment, heat exchangers, furnaces and inert gases. In situ coating process was applied to the nanoparticles. Sample analysis indicates that the particle size was less than 30 nm. In this study, it has been seen that t...

In this research work, deep machine learning-based methods together with a novel data augmentation are developed for predicting flicker, voltage dip, harmonics, and interharmonics originating from highly time-varying electric arc furnace (EAF) currents voltage. The aim the prediction is to counteract both response reaction time delays of active power filters (APFs) specifically designed furnace...

The gradual increase in industrial wastes allowed the utilization of these different areas. Steel slag, one wastes, is formed during reduction molten crude iron to steel basic oxygen furnaces (BOF) or scrap electric arc (EAF) and induction (IF). Removal, storage, disposal slag an important environmental economic problem. offers opportunities be used as alternative material various areas contrib...
